Proteins are organic macromolecules built from  adipose tissuepeptidesamino acidsfatty acids, bound together into long chains.There are about 20 different amino acids which can combine to make a molecule of protein. Some of the amino acids can be built by the body from scratch – for this reason they are called 'dispensable'. If an amino acid cannot be built by the body from scratch, it is called  a completea misoan essentiala high biological value amino acid and has to be provided as a part of a healthy diet.

There are  elevennineone hundredtwo essential amino acids and if they are all present in a molecule of protein, such protein is called a complete protein and has a  low biological valuehigh biological valueincomplete valuehigh energy value. If one or more of the amino acids is missing, the protein is considered  a low biological valuean essentialan unstablea stable protein.
