MIT study explains why dinosaur collagen survived for millions of years. Collagen, a protein prevalent in bones and connective tissue, has been discovered in dinosaur fossils as old as 195 million ...

A peptide bond is an amide type of covalent chemical bond linking two consecutive alpha-amino acids from C1 (carbon number one) of one alpha-amino acid and N2 (nitrogen number two) of another, along a ...

This interaction involves the sharing of electrons between neighboring peptide bonds, which keeps water molecules from ...

This generally occurs through protease-mediated hydrolysis of peptide bonds, but can also occur through non-enzymatic methods such as by action of mineral acids and heat. Ge, Zhou, Fu et al.

Proteases are enzymes that catalyse hydrolysis of the peptide and isopeptide bonds that join amino acids within proteins (known as proteolysis). Proteases can also remove protein post ...
