Collagen and albumin are:
Correct answer: A. Simple proteins
- A. Simple proteins
- B. Derived proteins
- C. Polyamides
- D. Polysaccharides
Explanation
A is correct as collagen and albumin are simple proteins,upon hydrolysis they produce amino acids only.B is incorrect as derived proteins are derived from simple proteins.C is incorrect as polyamide consists of repeating polymer units linked together through amide bonds.Collagen and Albumin have hydrogen bonds.D is incorrect as polysaccharide is a carbohydrate,whilst albumin and collagen are proteins.

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.
