difference between karatin and carotin
Answers
Answer:
Keratin (/ˈkɛrətɪn/[1][2]) is one of a family of fibrous structural proteins known as scleroproteins. α-Keratin is a type of keratin found in vertebrates. It is the key structural material making up hair, nails, feathers, horns, claws, hooves, calluses, and the outer layer of skin among vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals.[3][4] The only other biological matter known to approximate the toughness of keratinized tissue is chitin.[5][6][7] Keratin comes in two types, the primitive, softer forms found in all vertebrates and harder, derived forms found only among sauropsids (reptiles and birds). Keratin resists digestion, which is why cats regurgitate hairballs.
Spider silk is classified as keratin, although production of the protein may have evolved independently of the process in vertebrates
Explanation:
Carotene is responsible for the orange colour of carrots and the colours of many other fruits and vegetables and even some animals.
Lesser Flamingos in the Ngorongoro Crater, Tanzania. The pink colour of wild flamingos is due to astaxanthin (a carotenoid) they absorb from their diet of brine shrimp. If fed a carotene-free diet they become white.
