components, namely the mineral crystals and the organic matrix, can be discerned. The organic matrix of bone consists primarily of a fibrous protein, collagen, and lesser amounts of other noncollagenous proteins (discussed later). In tooth, collagen is also the major organic constituent of dentin and cementum, but there is no collagen in enamel. Collagen is the same protein that gives flexibility to ligaments and ten-
Proteins. Proteins are organic compounds that contain the element nitrogen as well as carbon, hydrogen, and oxygen. Proteins are the most diverse group of biologically important substances and are often considered to be the central compound necessary for life.here are obviously many types of proteins, but they are all made from amino acids bonded together by the dehydration synthesis. By continually adding amino acids, called peptides, two amino acids join together to form dipeptides; as more peptides join together, they form polypeptides.
