Amino acids all have a similar structure. They contain a central carbon with a carboxylic acid group, amino group, hydrogen and an R group which specifies the name of the amino acid. There are eleven non-essential and nine essential amino acids. Non-essential amino acids are produced at a sufficient rate by the body to meet its needs. Essential amino acids must be consumed in proper amounts to meet homeostatic needs. A complete protein contains all essential amino acids.
A peptide bond is formed by a condensation reaction between the carboxylic acid group of one amino acid and the amino group of another. There are peptides, polypeptides, and proteins. For proteins to be broken down and absorbed the enzymes must recognize these peptide bonds and create an environment to be absorbed. For this reason, free form amino acids are usually not absorbed very well or at all. Proteins perform many actions within the body including enzymatic, hormonal, transport, as well as structure, function, and regulation of tissues and organs. Not all proteins are enzymes, but all enzymes are proteins. So, one can see the vital roles protein plays in the body.
Appropriate protein intake is necessary for a client to succeed in a weight loss or gain nutrition program. Promoting lean body mass requires a positive nitrogen balance and enough consumed energy to lay down muscle. Weight loss while maintaining lean body mass also requires adequate protein. The appropriate protein level is energetically favorable for weight loss because it requires energy to remove the amino group during the process of deamination. Deamination takes place within the urea cycle and therefore increases urine production leading to a dehydration effect on the body. Bodybuilders and figure contestants consume the highest percentages of protein for these effects. Appropriate protein intake is important to reach desired goals and improve overall health.
