    Dang how did I just find your channel! I'm self-studying the MCAT and the biochem is so discouraging since I have not taken the course. I was just talking to a friend yesterday how I wished I had some help/guidance on the subject. A teacher who can not only teach the content but also enable the students to absorb the knowledge and make connections and make sense of all the chemical reactions happing in the head as we learn. And YOU ARE IT!! Thank you Thank you Thank you!!

I even went to a special cram school for my big exam and what the biochemistry teacher said I just couldn’t understand! It was so frustrating and now everything is coming clear as I go through your videos! Thank you medicosis!! Ilysm ❤

    Why does fully protonated amino is + charged, while the fully protonated carboxyl is not

    • @Vodnuth
      @Vodnuth 2 ปีที่แล้ว +3

      Good question, because oxygen atoms prefer 2 bonds the deprotonated form of COOH has a negative charge associated indicating that one of the oxygens has electrons it wants to share. Whereas when the C-N2 is protonated the N atom has 4 bonds and nitrogen prefers to form 3 bonds, so the postive charge indicates that it is sharing more electrons than it usually likes to. Hope this helps.

    I do not see why you included this one as #40 in the General Chemistry playlist. It assumes that the prior three Titration videos have been seen for it to make sense. All the while Acids and bases have not been covered as yet. Acids and Bases are covered in #55, so the cart has gone before the horse. Given all that - it is still an awesome presentation.
