Protein
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 enzyme 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 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. Visit
