BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Examples of fibrous proteins are -keratin, the major component of hair and nails, and collagen, the major protein component of tendons, skin, bones, and teeth.

Detailed explanation-2: -Keratin, collagen, and elastin belong to an important category of proteins within the human body, known as fibrous proteins or scleroproteins, which adopt filamentous, elongated conformations in contrast with typical globular proteins [1, 2].

Detailed explanation-3: -Fibrous proteins consist of many superfamilies including keratin, collagen, elastin, and fibrin. Collagen is the most abundant of these proteins which exists in vertebrate connective tissue including tendon, cartilage, and bone.

Detailed explanation-4: -Collagen is the most abundant protein in animals. This fibrous, structural protein comprises a right-handed bundle of three parallel, left-handed polyproline II-type helices.

Detailed explanation-5: -Keratin is a fibrous protein which can be classified into two groups: soft keratin and hard keratin. It forms the bulk of cytoplasmic epithelia and epidermal structures. Keratin is abundant in animal hair, nails, wool, horns, and other features [8].
