If any amino acids contain greater number of NH2, it is:
Correct answer: D. Basic
- A. Acidic
- B. Neutral
- C. Amphoteric
- D. Basic
Explanation
Amino acids with a greater number of NH2 groups (amine groups) are more basic because the amine groups can accept protons (H+ ions) and act as a base. The presence of more NH2 groups increases the basicity of the amino acid, as it can accept more protons.

About Classification of Proteins
Proteins are classified by composition as simple, conjugated and derived proteins, and by shape as fibrous or globular proteins. The topic relates these classes to examples such as albumin, keratin, collagen, haemoglobin and casein, while distinguishing structural proteins from proteins with transport, catalytic or regulatory roles.
