Abstract

The proteins of the human body are in a constant state of flux with some proteins being synthesized and catabolized continually. Dietary proteins and tissue protein breakdown products provide a pool of amino acids which provide the building blocks for formation of new protein for growth and for rebuilding tissue protein. Essential amino acids are those not synthesized by man or not produced sufficiently rapidly enough to support this activity. Therefore, man requires a source of nitrogen and essential amino acids to support growth, protein synthesis and biosynthesis of important nitrogenous metabolites. The differences in value of food proteins are due to variations in amino acid pattern of each protein. Since the body can form only some of the amino acids, nine “essential” ones must be supplied in the diet (Table I) (McLaughlan et al., 1963, Schelling, 1975). Protein normally is not absorbed by the human intestine, but its hydrolysis products peptides and free amino acids are readily absorbed by the small intestine and transported via the portal blood. A diet low in protein or food protein which is deficient in one or more essential amino acids will restrict protein synthesis. Nonessential amino acids are generally metabolized to pyruvate which leads to gluconeogensis. Therefore, in times of great need (starvation) body proteins can provide energy via glucose. The problem here is that the conversion of protein to glucose is only about 50% efficient (Bessman, 1975) so that 100 g of glucose will require 200 g of protein or the equivalent of 1 kg of lean body weight. Most of the essential amino acids are converted to acetyl CoA and their nitrogen as well as that of the amino acids converted to glucose is lost to the body primarily as ammonia.
