Amino acids are the building blocks of proteins, including keratin. Similar to how each human has their own string of deoxyribonucleic acid, each protein has a distinct order of amino acids (DNA). Keratin is typically present in epithelial cells, however it can also be found in interior organs and glands. Other animals' hair, nails, and hooves are mostly made up of keratins, a distinct family of fibrous structural proteins.
