Question

What kind of bond is a peptide bond of proteins?

Answer 1

Polypeptides and proteins are chains of amino acids held together by peptide bonds, as is the backbone of PNA.

Answer 2

A peptide bond (amide bond) is a covalent chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, thereby releasing a molecule of water (H2O)...(from wikipedia)

Answer 3

polypeptide bonds

Answer 4

the building blocks of protein are amino acids. Amino acids have two terminals, one has amino group (NH2) and other has COOH group i.e carboxyl group. Proteins are formed by joining several of the amino acids together. this joining between these two ends occurs with release of molecule of H2O

NH2-A-CO---OH +H---NH-A-COOH -----> NH2-A-CO-NH-A-COOH +H2O

Answer 5

also peptide bond is a covalent bond with a partial double bond character.
