Question

28. A link between amino acid molecules in a polypeptide chain by condensation reactin is
called
(a) peptide bond
(b) polypeptide linkage
(c) diol linkage
(d) amine linkage​

Answer 1

Answer:

The amino acid units are linked by peptide bonds (sometimes called peptide links).

Answer 2

Answer:

Let's carry out this same condensation reaction but using two amino acids. Under these conditions, the bond linking them is called a peptide bond, and this product is called a dipeptide. Longer chains, known as polypeptides, may contain 50 to 300 amino acid residues. The peptide bond is the strongest bond in a protein.
