Cracking Chirality: The Mystery of Mirror Molecules
ฝัง
- เผยแพร่เมื่อ 21 ส.ค. 2024
- "Cracking Chirality" from Chemistry Shorts™ explores how the essential molecules of life, like DNA, RNA, and proteins, acquired their homochiral structures and how magnetic rocks at the bottom of a prebiotic lake, may have set the stage for life as we know it.
In a mirror, our bodies appear symmetrical from the right to the left. But hold one hand on top of the other, rather than palm-to-palm, and you’ll notice that they are not in fact the same; they have a defined right- or left-handedness, or chirality. Look even deeper inside, at the molecular level, and you’ll find that many of the important molecules in our bodies are similarly right or left-handed, and exist in only one form or the other. We call this homochirality.
Chirality is the idea that some molecules come in two mirror-image configurations. Despite having the exact same chemical compositions, their physical structures are different. These left-handed and right-handed molecules can have different properties and functions. Understanding how chiral molecules function differently is essential to chemical synthesis and medicine. But it also holds a curious question about early life: why are the nucleic acids that hold genetic information in all of life right-handed, while the amino acids that they encode left-handed?
In "Cracking Chirality,” two Harvard University scientists, Dimitar Sasselov and Furkan Ozturk, present their exciting new findings: magnetized molecules found at the bottom of lakes on the primordial Earth may be the key to how important biological molecules crystallized and grew, tipping the scales from a 50-50 mixture of molecules to homochiral solutions made up of just one or the other. Their simple experimental setups, growing crystals on tiny magnetized plates, help provide a solution to an essential question about life itself that has plagued scientists for decades.
“Life's polymers from DNA, to RNA, to the proteins, cannot really function if they're a mess of left-handed and right-handed molecules. They have to be clearly homochiral. And you need to do something very special to break that symmetry. It is still a big mystery of how this happened at the origin of life. And our work is trying to answer that question.”
- Dr. Dimitar Sasselov in “Cracking Chirality.”
“Cracking Chirality” is targeted towards high school and college students, and can be used as a starting point for discussions around the chemical origins of life, molecular chirality, electron spin, magnetism, and more.

@@üniversiteliyksadayı Teşekkürler, umarım ileride ben de Furkan Öztürk gibi bu videolarda yer alarak tekrardan "Sizi buralarda görmek güzel" dedirtebilirim :)
Go Furkan! Your work and questions are exciting and inspiring. Even if I heard about chirality from Death Stranding first, which is a shame. Still, I can barely earn my bachelors at your age, so not that surprising lmao
İyi ki varsınız! 🇹🇷 🎉
Türk gençleri için örnek bir cumhuriyet genci👏🏾👏🏾
Siz iyi ki varsınız sizin gibi gençler iyi ki var😊
Sen de iyiki varsın Hocam:)
Muazzam🤍❤️
Helal olsun
Türk gençlerini araştırırken, üretirken görmek bir Türk genci olarak bana çok ilham veriyor bu yüzden size çok teşekkür ederim! Ayrıca belgesel de çok başarılı, tebrikler :)
Kesinlikle bende türk gençlerinin bir turk genci olarak bilim yapmasına ve araştırma yapmasından son derece memnunum ben de aynı şekilde bu kanaldaki olan hesaplamalı evrenle alakalı videoyu izledikten sonra bir bilgisayar bilimi öğrencisi olarak ileride fizik doktorası düşünüyorum ileride çünkü bilgisayar bilimi ve fiziğin birleşimi çok ilgimi çekiyor feynman turing von neumannları okuyunca bu alan çok ilgimi çekti benim de kısaca hikayem öyle:)
We're so glad you liked it!
Go back where you came from. We don't want you here
her türlü yakıyom sigara
It was inspiring for Turkish scientist candidates. Thank you Furkan
We're so glad you liked it!
Love you all ❤
Not only a good scientist he is a good storyteller
We agree! :)
100 years ago, Mustafa Kemal Atatürk, the founder of the Republic of Turkey, showed how much he cared about education by organizing an education congress with teachers despite the war during the War of Independence. Furkan Öztürk has brought pride and honor to Atatürk's humble body with the work he has done today. Thank you, brother Furkan.☺️🙏🏻

@@SFurkanOzturk61 abi başarılarının devamını dilerim. Sana bir soru sormak istiyorum. Benim İngilizcem A1 bile değil öğrenmeye başlamak istiyorum ama nasıl başlayacağımı çözemiyorum. Sence ilk nasıl başlamalıyım?
Şimdiden teşekkür ederim. 😊🙏
Thank you for watching!
All humanity should be proud of you for fulfilling the words of the Great Leader Mustafa Kemal ATATÜRK: "I love the young people who see beyond the horizon, not the horizon." Thank you very much. 🙏🙏
Felsefeci Robert P. Crease'ın 2019'da yazdığı ve Atatürk'ün de dahil edildiği, "Bilim Devrimcileri" adlı kitabını herkese önerelim o zaman. ❤😊
This whole video is excellent, but I must say that the researcher climbing the stairs while spinning at the end was particularly delightful.
Thank you! We like that part too :)
Sevdiği şeylerle uğraşan insanın yüzündeki o mutluluk ,Furkan abide ben bunu görüyorum ve gerçekten bu çok özel yolun açık olsun...
Thank you for watching!
Go back to mongolia
❤❤
The cameraman did a great job, it elevates the story being told. Congratulations.
Our production team is the greatest! Thank you for watching.
Bir Peter Higgs hayranı olduğum doğrudur. Artık Furkan Öztürk hayranlığım da aynı seviyede.
Thank you for watching!
As a YKS student, this video was motivating for me. One day, we can reach the same places and be more successful. Thank you, Furkan Öztürk
You can do it! Thank you for watching.

Bilim hayatın ta kendisiyken onu anlaşılmaz kılmak, teknik terimlerle herkesten soyutlaştırıp sadece kendi kitlesi içinde var etmek de bir seçenekken yapılan kıymetli işleri daha anlaşılır kılmak için gayet komplike olan şeyleri basitleştirmek ona asıl hizmet eden ve aslında en zor olan şey. Bunu başardınız. Dimitar Sasselov, Chemistry Shorts ve Furkan Öztürk Hepinizi tebrik ederim. 👏🏻 Görseller, müzikler, anlatım şahaneydi. Eminim her kitle kendini bu büyülü dünyayı merak ederken ve anlamlandırabildiğini görüp sevinirken bulacak. Furkan’ın heyecanını ve mutluluğunu paylaşıyoruz. 🇹🇷Gurur duyduk bir kez daha 🤍🥹
Narcissus’un hikayesini yorumlayış biçimine ve bu belgesele bağlayışına bayıldım bu arada 😁
We appreciate your comments! Thank you for watching.
Bizlere ilham olduğun için teşekkürler Furkan abi!
Furkan inspires us too!
Go back to mongolia. Constantinople is greek.
From Turkey, thanks ❤
From NYC - thank you for watching :)
Yorumlarda furkan abinin ne kadar çok insana ilham verdiğini görmek çok güzel

Gurur duyduk ağabey. Senden çok şey öğrendik. Umarım başarıların daim olur ve kafanda canlandırdığın en yüksek potansiyeline ulaşırsın.
Thank you for watching!
As a Turkish chemist, I am beyond proud of Furkan Ozturk👏🏻
Wow Furkan it is fascinating, it is also so understandable. Well done 👏👏
We are so glad you liked it!
Keşke bu tür bilimsel çalışmalar ve projeler daha da yaygınlaşsa.Ülkece gereksiz şahısları takip edip onları fenomen yapmaktansa bu tür bilim insanlarını ileriye taşımayı yeğlerim.Bilmem anlatabildimmi.Furkan Türkiyenin örnek bir insanı olduğun için sana minnettarım.
Benim gibi gençlere esin kaynağı oldun.Biz Türk gençlerinin en çok da benim böyle bir emsale ihtiyacımız vardı.❤
Thank you for watching!
Çok teşekkür ederim. İnsanlık tarihindeki en önemli , necisiniz, nereden geldiniz, nereye gidiyorsunuz üç sorusuna cevap verilebilecek binlerce çalışmalardan birini daha açığa çıkarmanızı tebrik ediyorum.

hey people look out! i can easily foresee that this work will come with a nobel prize soon!
Thank you for watching!
Gurur 😍👏🏻
Thanks for watching!
Amazing production, such a hard concept and you made easier to understand.
Happy to hear that!
Bizim üniversitelerde olmayan şey bir astrofizikcinin moleküller biyolojiye girmesidir, farklı alanlardaki bilgi birikiminin yararlı olabileceği her zaman hesaba katılmalıdır, sadece bu yaklaşıma sahip olmanız, oradaki bilim insanlarının bunu desteklemesi bile takdire değerdir. Örnek almalıyız.
Thank you for watching!
su kotu gunlerde,su kadar gurur verici bir abiye sahip oldugumuz icin o kadar mutluyum ki daha nicelerine insallah🤍
Thank you for watching!
This is groundbreaking. This is such a large piece of the puzzle and yet confirms whats I understand to be true. There’s a medium by way of "scaffolding" rather than specific elements that create what we see. This might also explain the stimuli that the living dervives from its environments such as one would seek a reflection. I mean by way of connecting why we adapt to what we respond to in our environments and the casual link between us the macro and particle influence and orientation, which would be micro
WOW, its amazing!!
Thank you!
You have answered a question that has been eating at me since my freshman year at UC Boulder, over 40 years ago.
Wow! Glad we could help :)
Dear Furkan,
Well, I really do not know what to say! You are a great detail, and endless thank you for enlightening us on the origin of the life in the name of Science. Hoping that the number of enlightened and curious young people like you will increase dramatically day by day. This is a great production, thank you to all the team who contributed on the broadcast. We look forward to seeing you sharing your exciting findings with us.
All the best🤗😇🤩
We are so glad you liked the film!
Awesome knowledgeable video...make many more of such this...
We're on it!
Great production, simplicity for the people who don't have a background on the matter, and detail for science enthusiasts balanced perfectly. Congrats Furkan, I hope this will be just the start on the matter
Thank you for such a thoughtful comment!
I love when these kinds of esoteric, almost mystically obscure facets of reality that seem intractable, as if they were true 'givens', nevertheless succumb to good elemental reasoning and reduction.
How Amazing work. Congratulations from Ankara, Turkey. God bless You.
Thank you very much!
ınanılmaz bir video, ve bir deha. Çok gurur duyuyorum, en büyük hayalim onun gibi biri olmak. Bu video bana çok ilham olucaktır. Emeğinize sağlık.
Such a sophisticated young man , I wish the best for your next academic career.🎉
Thank you for watching!
We are all proud of you Furkan Öztürk ! ❤🇹🇷 thank you for being an example to me and many young people who love science like me. You are a great idol ! thank you to those who prepared this video for doing a great job ⭐
We're really glad you liked the video!
Super - truly conclusive experimental demonstration; a joy to watch. May I mention that a few years ago I had the fortune to see a crescent moon just after sunset with Venus very close in the picture. As the sky darkened to night I noticed the shadowed part of the moon was actually visible(!) because of illumination from sunlight reflected off planet Earth (I learned about Earth-shine). It was a revelation - suddenly I saw the whole night sky in its true 3d perspective.
Thank you for sharing that with us! We're glad you liked the video.
The video was amazing, thank you to everyone who contributed, especially Furkan Öztürk, science is exciting!
Science IS exciting! :) Thanks for watching.
It will not be too long before Furkan Ozturk win the Nobel for his successful discovery on chirality Turkish Americans are very proud of you young man.🇹🇷🇹🇷🇹🇷🇹🇷🇹🇷

Holy cow I'm so glad I stumbled upon this channel. Just subscribed. I could literally watch footage on this kind of stuff every day! The quality is our of this world. It's always been a dream of mine to even get a job helping a researcher, laboratory, or field work studies. I really hope to see this field of study advance because it can greatly improve our understanding of the world around us. It's amazing
Thank you for subscribing and watching!
Merhaba Furkan hocam. Ben Ceylin.Sizi kendime çok benzetiyorum. Olaylara ve dünya ya farklı bakış açılarıyla bakıp yeni şeyler keşfediyoruz. Bence bilim insanlarının ortak noktası bu. Olaylara ve dünyaya farklı bakış açılarıyla bakıp aslında gerçekte var olan fakat kimsenin farkına varmadığı şeyleri ortaya çıkarıyoruz.O yüzden sizi bu keşfinizden dolayı tebrik ediyorum. Başarılarınızın devamını diliyorum.Gelecek yılarda sizinle çalışmak dileğiyle…
Thank you for watching!
Beautiful production. It, and the eloquent testimony of the scientists, gives a strong impression of the wonder of this mystery.
Thank you!
This is one of the most beautiful videos I’ve ever seen about chirality
Thank you!
Marvelous, Brilliant.
Thank you!
I loved end of the documentary.Everyone says that there are no emotions in science but science began with curiosity.And you feel safe when you reach and know something about science .As a Turkish person, I'm honored and thank you for this amazing documentary.
Well said!
Milli gururlarımızdan biri, Tebrikler Furkan!

Thank you for watching!
Hayatımda izlediğim en güzel belgesellerden biriydi.
Thank you for watching!
Really thanks for sharing this incredible background of the scientists...more away from the so interesting research in Origin of life-prebiotic chemistry- Chirality...I felt so connect with Sasselov, since he himself said he would never had thought to be studying chemistry since he had ever hated it...I'm in almosttttt a same situation with a difference...I love Chemistry, also Astronomy and Biology and I've been feeling pressure just for having to choose one to start a scientific carrer if I want to get closer to one of my dreams ...study in a field that link these beautiful areas can be possible while doing it just following what I like, without prejudices or "ideals" of what I should do/follow... ❤
Dr. Sasselov is so inspiring! We're glad you liked the video.
Hey if you are thinking about adding Turkish subtitles to the video and aren't already working on that, could i translate the video to Turkish and send the translation to you? I wanna help with the video voluntarily. Loved the video btw. Thank you Furkan for making us proud!
Thank you for the offer! We're looking into this already now. :)
I proposed this study to a ludite in my alma mater back in 2013. They were not interested and I have to say what a loss. Congrats to this team for advancing science. Aminoacid chirality was one of the big questions I had back in 1994 and then again in late 2012. Thank you for your contributions!!!
Thank you for watching!
We are here as the students of Furkan 🇹🇷
We're so glad to have you here!

Sanatla ilgilenen ve muhtemelen ömür boyu da sanatla ilgilenecek biri olarak bilimin verdiği ilham çok büyük. Bilim insanlarının içindeki o evreni keşfetme arzusu, gözlerindeki ışıltı o kadar umut ve ilham verici ki! Gezegenimiz ve evren hakkında daha çok şey biliyor olmamızı bu gözlerdeki ışıltıya ve keşfetme arzusuna borçluyuz. Furkan’ın ve ekibinin yaptığı araştırmanın önemini daha iyi kavradım, çok açıklayıcı bir video olmuş. Teşekkürler!
