(Science: biochemistry) A peptide of a small number of component amino acids as opposed to a polypeptide. Exact size range is a matter of opinion but peptides from 3 to about 40 member amino acids might be so described.

Re: Enzymes

... (there are thousands of enzymes!). I mean, that pepsin has nothing to do with saccharides, so its substrate is some polypeptide and product some oligopeptide. On the other hand, amylase (enzyme (everything ending in English with -ase is enzyme; everything ending with -ose is sugar/saccharide;)) ...

bacterial cell walls and digestion by proteases

... to be. Such an escape can be achieved if we make two assumptions: 1. The organisms use a protease which recognizes “usual” L-amino acids. 2. The oligopeptide bridges of peptidoglycan contain only D-amino acids. Then L-peptidase cannot digest D-amino acid bridge. Let’s look at Bacteria cell wall. ...

Polymerize and Depolymerize

For my example i take proteins. You;ll probably know that proteins are polymers of aminoacids. For example consider the oligopeptide Arg-Lys-Cys-Pro-Met then the chain Arg-Lys-Cys-Pro-Met is a polymerized structure. When it is hydrolized, we depolimerize the oligopeptide to: Arg + ...
