How many of the following statements are correct (I) Polysaccharides are present in an acid insoluble pool. (II) Protein is a homopolymer. (III) In a polypeptide chain, the last amino acid called the N-terminal amino acid. (IV) The tertiary structure is absolutely necessary for the many biological activities of proteins.

Options

  1. A4
  2. B3
  3. C2
  4. D1

Correct answer

C. 2

Step-by-step solution

Proteins are heteropolymer, they can never be homopolymer as they are made up of 20 different types of amino acid. In a polypeptide first amino acid is N - terminal end and the last amino acid is the C - terminal end.
