Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Hydrogen bonds link amino acids together.
A
TRUE
B
FALSE
Explanation: 

Detailed explanation-1: -Secondary structure The most common types of secondary structures are the helix and the pleated sheet. Both structures are held in shape by hydrogen bonds, which form between the carbonyl O of one amino acid and the amino H of another.

Detailed explanation-2: -The amino group of one amino acid interacts with the carboxyl group of another amino acid and releases a water molecule as two amino acids are covalently bound by a peptide bond.

Detailed explanation-3: -A hydrogen bond is mainly formed between a donor atoms such as an amine, which acts as a ligand, or a lewis base and acceptor atom like carboxylic acid. The larger the number of amino acids in a given protein molecule, the greater is the probability of the formation of hydrogen bonds.
