BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins, carbohydrates and lipids are made from three basic molecules: carbon, hydrogen and oxygen. However, all proteins contain an element not found in carbohydrates and lipids is nitrogen. Nitrogen which is present in all amino acids (the building blocks that make up the protein chains).

Detailed explanation-2: -In amino acids Nitrogen is the Major element that is present. Amino acids are compounds containing carbon, hydrogen, oxygen, and nitrogen. Whereas carbohydrates are compounds containing CHO, which includes carbon, hydrogen and oxygen.

Detailed explanation-3: -There are three amino acids that have basic side chains at neutral pH. These are arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base.

Detailed explanation-4: -Proteins are made of smaller molecules called amino acids. Each amino acid is made of different atoms, but they all contain nitrogen (N).

Detailed explanation-5: -Amino acids differ from each other with respect to their side chains, which are referred to as R groups. The R group for each of the amino acids will differ in structure, electrical charge, and polarity.
