    So what's released is a NH2-R and COOH-R with the enzyme acting as catalyst, here it is seen that amine and an acid is released, this shows that serine protease releases acids and amines, so is the protease inhibitors targeted to supress the release of excess acids and amines, (in this case of the serine protease) of course there are other proteases but an analogy can be assumed

  • @yashparikh7970

    that was an awesome explanation. tysm. sir in 2 nd stem how come the carbon had double bond even after forming tetrahedral confirmation with oh here instead of nh in first step where it was a single bond.

      +yash parikh Hello Yash, thx for your kind comment. As I am only the CZcams manager at Lecturio Medical Education Videos, this detailed question is a bit to difficult for me to answer. But did you know that we also have an elearning plattform for medical education where you can watch even more free lectures and ask questions to the professors. Try for free at www.lecturio.com/medical-courses Thanks again!

  • @dlajapal
    @dlajapal Před 7 lety +1

    Hi! I followed this to a T, thank you so much for explaining it in such depth. I do however have one question. Around 9:10, right when the NH2R gets released, and the remaining portion of the peptide covalently bonds to Serine, there seems to be a missing CH2 on the serine side-chain. I could be wrong, but that's the only part I am not following. Thank you again!

    • @lecturiomedical
