Detailed explanation-2: -Keratan | C28H48N2O32S4-PubChem.

Detailed explanation-3: -Essentially composed of keratin, hair also contains other elements and molecules that contribute to its appearance and behaviour. The overall chemical composition of hair is 45 % carbon, 28 % oxygen, 15 % nitrogen, 7 % hydrogen and 5 % sulphur. The hair shaft is essentially composed of keratin.

Detailed explanation-4: -What is keratin made of? Keratin isn’t a single substance. It consists of many different proteins, including various types of keratins, keratin-associated proteins (KFAPs) and enzymes drawn from animal tissues.
