The Chemistry of Biology: Proteins. 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.
Proteins are molecules made of amino acids. They are coded for by our genes and form the basis of living tissues. They also play a central role in biological processes.For example, proteins catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell.ideo: Role of proteins in human development. Each protein has a specific role in our body. However, scientists have discovered that some proteins perform more than 1 role. For example, Dr Julia Horsfield leads the Chromosome Structure and Development Group at the University of Otago.
