Proteins

Proteins are molecules made up of amino acids that are essential to all living things. They are the building blocks of cells and are involved in many biological processes such as metabolism, cell signalling and genetic regulation. Proteins have wide-ranging functions, including acting as enzymes, hormones, antibodies, structural components and many more. Proteins are also essential for muscle growth and repair, as well as immune system function. Thus, proteins are essential for normal growth and development, both for humans and other organisms.
