How does peptide bond formation really happen? Like biochemically, not just in-a-lab-by? If you were one of those people like me who got frustrated/disappointed when in o-chem they teach you it’s a condensation/dehydration reaction and then say – but that’s not how it really happens in your body, this video is for you!

No new text, but I have lots more about translation here: blog form (also has static figures): ; video:

And sorry for the bad cinematography – I was balancing my phone on a box…

for more information – here are some scientific articles I got info from and a couple websites
