BIOMOLECULES AND ENZYMES

Detailed explanation-1: -To form polypeptides and proteins, amino acids are joined together by peptide bonds, in which the amino or NH2 of one amino acid bonds to the carboxyl (acid) or COOH group of another amino acid.

Detailed explanation-2: -Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Detailed explanation-3: -These molecules are called amino acids because they all share two functional groups in common: an amine group (-NH2) and a carboxylic acid group (-COOH). With the exception of proline, they all have the same backbone: NH2-CH-COOH.

Detailed explanation-4: -A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule; thereby, releasing a molecule of H2O.
