BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -The alpha carbon (-carbon or C) is what connects the amino group to the acid carboxyl group, giving amino acids their name. The alpha carbon also serves as the point of attachment for the sidechains of 19 out of 20 amino acids used in protein building.

Detailed explanation-3: -Peptide bond: A covalent bond joining the -amino group of one amino acid to the carboxyl group of another with the loss of a water molecule.

Detailed explanation-4: -Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the carbon. Each of the 20 amino acids has a specific side chain, known as an R group, that is also attached to the carbon.
