BIOMOLECULES AND ENZYMES

Detailed explanation-1: -So, the correct answer is ‘Albumin’.

Detailed explanation-2: -Fibrous protein is the protein in which the polypeptide chain runs parallel and the two chains are held together by the disulphide bonds and hydrogen bonds. And these proteins are not soluble in water. Some examples of fibrous protein are myosin (present in muscle) and keratin (present in wool, silk, etc.)

Detailed explanation-3: -Out of the three kinds of proteins, it is the only one that is insoluble in water. This is because water is a polar solvent and only polar solutes can be dissolved in it. Fibrous proteins are always covered in non-polar amino acids, thus making them non-polar solutes.

Detailed explanation-4: -Fibrous proteins are usually static molecules and play important structural roles in the anatomy and physiology of vertebrates, providing external protection, support, shape, and form. They are water insoluble and are typically built upon a single, repetitive structure assembled into cables or threads.

Detailed explanation-5: -Collagen is an insoluble fibrous protein of chief importance for proper structure of bones, tendons, skin, among other tissues, and organs.
