Dude. I have a job interview for a CTA spot in a peptide synthesis lab tomorrow, and I was looking for a relatively simple explanation on the Strecker synth. Great video!
Hey professor, not sure if you've been requested this or already done it, but can you do some content explaining general relativity, black holes, gravity and singularity? Thanks boss.
Hey Dave nice video! I was wondering, at 4:06, you mention the formation of a chiral salt, however the compound illustrated has no charges shown ? I get that the final compound will be ionised in biological pH but not the chiral salt you mention. Thanks in advance !
If you look at the mechanism discussed earlier, with the ammonia, you can see that not the imine, but the protonated imine is nucleophilically attacked by the cyanide. In this example the imine is prepared beforehand, thus during the reaction it is first protonated and forms the chiral imminium phosphate adduct (salt) with the catalyst which directs the stereo selectivity. Though I haven't checked the original publication, the authors may propose a different mechanism.
Many more than 20, actually. There are 20 proteinogenic amino acids (amino acids that compose proteins), but far many more non-proteinogenic amino acids.
I like your funny words, Chemistry Man
I love your hilarious statement, Comment dude
have an exam tomorrow, and ı was stuck with this. You saved me professor Dave. THANK YOU

Pls Tell me it went well
I feel like this was made just to piss james tour off

Check my modern physics and astronomy playlists!
@@ProfessorDaveExplains sure, thanks! 😊
Ayyy nice new upload

when is the debunking of "water" video coming out?
next month some time
The haircut looks great. By the way, how did they prepare the pure enantiomer of the acid catalyst?
Professor Dave, when can we expect engineering playlist? the topics were too brief in Classical Physics
I am planning an extension to the CP playlist for more rigorous E&M content and am also just starting to plan engineering, so probably next year!
@@ProfessorDaveExplains just curious do u plan to debate anytime soon
@@ProfessorDaveExplains cool ! thx
So is this how they make amino acids for supplements like BCAAs?
I did not get the notification for this video
Weird
When are you gonna do Bush Jr
Professor plz help us to get atleast 150 marks in chemistry for competitive exam (NEET UG).....
@Ranker's Journey oh then his video's are not useful for neet a???
I don't want to be the guy, but the amino acids in the first few slides are the wrong isomer
How many types of amino acids are there?
20

Carbon acid
Hi prof. I'd like to subscribe to your channel but that profile picture of yours doesn't allow me.
just click the subscribe button
wow

Can you speak khmer?
no, not even a little bit
I do however speak some German and also a tiny little bit of French
