Protein GapFill

Proteins are organic macromolecules built from  adipose tissuepeptidesfatty acidsamino 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  an essentiala high biological valuea completea miso amino acid and has to be provided as a part of a healthy diet.

There are  one hundredninetwoeleven essential amino acids and if they are all present in a molecule of protein, such protein is called a complete protein and has a  high energy valuehigh biological valuelow biological valueincomplete value. If one or more of the amino acids is missing, the protein is considered  an unstablea low biological valuea stablean essential protein.

Proteins are necessary to build  tooth enameladipose tissueunsaturated fatall cells in the body , enzymes and hormones. They can also be used as a  essential minorfreeprimarysecondary source of energy – this means that they are only used as a source of energy if other sources (carbohydrates and fats) are not available.

If a person eats too little protein, they may develop a disease called  kwashiorkorkidney stonesberiberiscurvy. Too much protein can also be harmful for the body, causing harm to the liver and the kidneys.
