Answer:

A is the correct

Answer 2

Answer

The fibrous proteins do not have coiled peptide chains.

Explanation

They are insoluble in water. The nonpolar groups of amino acids protrude at the surface of the fibrous protein making its surface hydrophobic. So, fibrous proteins are insoluble in water.

Fibrous protein is a type of protein. Proteins have a high molecular weight. So, fibrous protein has a high molecular weight.

The Peptide chains in the fibrous proteins are elongated and run nearly parallel to a fixed axis. So, they are not coiled like structures.

Being elongated structures, the fibrous proteins have an axial ratio of more than 10.
