Which of the following best describes the molecular structure of ovalbumin?
A group of six carbon atoms joined in a ring.
A chain of amino acids folded and twisted into a molecule.
A set of three fatty acids attached to a molecule of a glycerol.
A sequence of nitrogenous bases attached to a sugar phosphate backbone.
Answer:
Option (2).
Explanation:
Ovalbumin is the protein present n the egg white and constitutes more than 55% of the egg's protein. The ovalbumin acts as the main storage protein of the eggs.
Proteins are the polymers of the amino acids. As ovalbumin is protein, it must contains the chains of the amino acids linked together through peptide bond. The chains of amino acids folds, twist in a proper manner and attains the particular 3D shape of the protein.
Thus, the answer is option (2).
