The Amino Acids in Proteins are Joined Together by _____

Question

The amino acids in proteins are joined together by _____ bonds.
A)peptide
B)hydrogen
C)ionic
D)acetyl
E)oxygen

Accepted Answer

Amino acids in proteins are joined together by peptide bonds between the carboxyl group (COOH) of one amino acid and the amino group (NH2) of another amino acid. Hydrogen, ionic, and oxygen bonds may also be present in proteins, but they do not join the amino acids together in the primary structure. Acetyl bonds are not involved in protein synthesis.
