Question 3 Some globular proteins are water soluble, while all fibrous/membrane proteins are water insoluble. Which of the following statements BEST explains the reason for these differences? A Fibrous proteins have a large number of hydrogen bonds between the amino acids in the polypeptide chains that stabilize their structures, preventing solubility in water. The globular proteins that are water-soluble do not have as many hydrogen bonds between the amino acids in their peptide chains, allowing water solubility. B Fibrous proteins are configured in a way that exposes the polar side chains of the amino acids on the surface of the protein, preventing solubility in water. The globular proteins that are water soluble have nonpolar side chains on the surface of the protein, allowing water solubility. C Some globular proteins are configured in a way that exposes the polar groups of the amino acids on the surface of the protein, allowing water solubility. Fibrous proteins have nonpolar side chains on the surface of the protein, preventing water solubility. D Some globular proteins are composed of more than one polypeptide chain that weakly interacts with one another, allowing water solubility. Fibrous proteins are composed of only one polypeptide chain that tightly folds, preventing water solubility.

Globular proteins are spherical proteins which are water soluble and forms colloid in water.

The best statement which will explain the reason for difference in globular protein and fibrous proteins is statement C.

C. Some globular proteins are configured in a way that exposes the polar groups of the amino acids in the surface of the protein, allowing water solubility.

Fibrous proteins have non polar side chains on the surface of the proteins, preventing water solubility.

Globular proteins are water soluble. Fibrous proteins are not soluble in water.

Amino acids chain prevents folding up so that the chain is not broken and it remains in elongated form. The correct answer is C.

Answer: A Fibrous proteins have a large number of hydrogen bonds between the amino acids in the polypeptide chains that stabilize their structures, preventing solubility in water. The globular proteins that are water-soluble do not have as many hydrogen bonds between the amino acids in their peptide chains, allowing water solubility. Explanation: Globular proteins are generally more water-soluble than fibrous proteins because they have fewer hydrogen bonds between the amino acids in their polypeptide chains, allowing them to be more flexible and hydrated. Fibrous proteins, on the other hand, are more rigid because of the large number of hydrogen bonds between the amino acids, leading to less solubility in water.
