What is protein catabolism?
Protein catabolism is the breaking down of proteins in the body. More specifically, protein catabolism is the breaking down of proteins into various amino acid constituents, and some other simple, insignificant compounds. Proteins are broken down in order to make certain amino acids available for polymerisation (formation of different proteins). RNA (ribonucleic acid) and ribosomes are also utilized. Alternatively, amino acids which result from protein catabolism are immediately able to be used to manufacture new aminos – or various other compounds via the actions of the Krebs Cycle.
