Question

1. the bond that joins amino acids in a protein chain is called a:

(1 point) *

a) hydrogen bond
b) ionic bond
c) peptide bond
d) disulfide bridge

Explanation:

A peptide bond is formed between the carboxyl group of one amino acid and the amino group of another amino acid, linking them together in a protein chain. Hydrogen bonds are weaker bonds that contribute to protein structure (e.g., in secondary structure like alpha - helices and beta - sheets). Ionic bonds are electrostatic attractions between charged groups. Disulfide bridges are covalent bonds between cysteine residues that help stabilize the tertiary structure of proteins.

Answer:

C. Peptide bond
