What is the covalent bond of proteins?

Answer 1

A special form of an amide bond called a peptide bond.

Disulfide bond is also a covalent bond found in proteins, but it is only binds 2 sulfur containing amino acids.

Answer 2

Proteins are made up of amino acids linked together by covalent bonds called peptide bonds. These bonds form between the carboxyl group of one amino acid and the amino group of another amino acid, resulting in a linear chain of amino acids called a polypeptide chain.

Answer 3

peptide bonds and disulfide bonds(disulfide bond found only between sulfur containing amino acids eg:cystine)

Answer 4

It is Peptide bond. Peptide bond is a type of covalent bond that forms between the carboxyl group of one amino acid and the amino group of another amino acid molecule.

Answer 5

Bonds in proteins can be molecular and ionic which results in proteins having up to four structures - primary, secondary, tertiary and quaternary
