BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Collagen, keratin, elastin, silk, and fibrin are examples of fibrous proteins.

Detailed explanation-2: -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-3: -Collagen is an abundant fibrous protein in vertebrate animals being found in tendons, cartilage and bone, and it has a unique structure. Elastin is an important component of tissues, such as ligaments and skin, and is highly elastic.

Detailed explanation-4: -Examples of fibrous proteins are keratins, collagens, myosins, and elastins. Hair and the outer layer of skin are composed of keratin. Connective tissues contain collagen. Myosins are muscle proteins and are capable of contraction and extension.

Detailed explanation-5: -Fibrous proteins are long chains. They are made up of repeated amino acid sequences that form long polypeptide chains. These chains twist together to form fibrous proteins. Fibrous proteins are water insoluble.
