Amino acids are joined together in proteins by?

Question

A. ionic bonds

B. peptide bonds

C. adhesion

D. electron transfers

E. none of the above

Answer 1

Peptide bonds.

Protein segments are also referred to as polypeptides.

Answer 2

PEPTIDE BONDS

Answer 3

Peptides (from the Greek πεπτίδια, "small digestibles") are short polymers formed from the linking, in a defined order, of α-amino acids. The link between one amino acid residue and the next is known as an amide bond or a peptide bond.

So the answer is B

Answer 4

peptide bonds

The bottom of the one amino acid has a carboxyl group.

         C=O

         !

         OH

The top of the next one has an amino group

         N-H

         !

         H

The OH of the carboxyl group and the H of the amino group bond to form H2O which splits out. The C then bonds with the N.This is a peptide bond.

Answer 5

the answer is B.
