BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Myosin, collagen and keratin are all examples of structural proteins. Myosin is the major constituent of muscles, collagen is majorly present in connective tissue, and keratin is an integral part of hair and outer layers of skin.

Detailed explanation-2: -Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.

Detailed explanation-3: -Examples of structural proteins can be keratin, collagen, and elastin. Keratins are found in hair, quills, feathers, horns, and beaks. Collagens and elastin are found in connective tissues such as tendons and ligaments. Collagen is recognized as the most abundant mammalian protein.

Detailed explanation-4: -Structural proteins such as collagen, fibronectin and laminin are utilized in cell culture applications as attachment factors.
