Protein and the human body

Whey proteinThe average human body is made up of 60% water, 17% fat and only 5% carbohydrate.

Protein comprises a similar proportion of the body as fat at 17% and forms essential components of all body tissues structure such as cell membranes and genetic material and plays a major role in metabolic systems in the form of blood hormones, antibodies and enzymes.

All protein in the body has a function and as such there is no storage pool of protein as there is for fat in the form of adipose tissue or carbohydrate in the form of glycogen.

Body protein can be divided into three functional pools which are listed in order of size with muscle mass being the largest:

1) Muscle protein
2) Visceral (abdominal organs) protein
3) Plasma proteins and plasma amino acids
