WebHCl activates pepsinogen to convert it to pepsin... pepsin breaks peptide bonds (it is an endopeptidase which cleaves AAs from within the chain). HCl DOES NOT do anything to the PEPTIDE bonds, you need the enzyme pepsin to do this, but HCl does disrupt tertiary structure (changes the pH so that charged AAs change) pepsin disrupts secondary and … Web5 jun. 2024 · Pepsin is originally secreted into the stomach as a proenzyme - an inactive precursor to an enzyme - called pepsinogen. When food is ingested, both pepsinogen and hydrochloric acid are released into the stomach. Returning to our primary structure, pepsinogen possesses 44 additional amino-acids compared with the active enzyme.
