Study Notes

Peptide Bond and Enzymes

The halflife of the peptide bond in peptides and proteins under physiological conditions is unknown, but it's extremely stable, with a half-life of several years.
Enzymes are biological molecules, typically proteins, that speed up chemical reactions in living organisms.
A catalyst is a substance that increases the rate of a chemical reaction without being consumed or altered in the process.
The enzyme trypsin is synthesized in the pancreas and helps break down dietary proteins in the small intestine.
Most enzymes are made of proteins, although some are RNA molecules.
