Master Amino Acid Pattern / MAP (Product ProShape), as a dietary proteins substitute, has a 99% NNU / Net Nitrogen Utilization.
This means that 99% of MAP´s constituent amino acids followed the anabolic pathway, thus acting as precursor
of body´s protein synthesis (building blocks).
By comparison, dietary proteins only provide between 16 to 48% NNU. To illustrate: hen egg protein,
considered, so far, the dietary protein with the highest in biological value, provides only a 48% NNU, which
still is 51% less than that provided by MAP; soy bean, casein as protein source provide approximately a 17% NNU.
This fact evidences that MAP is more nutritious than dietary proteins.
1% of MAP´s constituent amino acids followed the catabolic pathway, thus releasing only 1%
of nitrogen catabolites and energy. This fact evidences that MAP is safer
than dietary proteins, does not impair the renal and hepatic function, and
provides the lowest amount of energy in comparison to any dietary protein.
To illustrate: when a dietary protein is digested, it releases its
constituent amino acids into the small intestine, where they
are absorbed. Then, those amino acids can follow either the
anabolic pathway or the catabolic pathway (Fig. I).
Figure I. Dietary Protein Metabolism
When dietary amino acids follow the anabolic pathway,
they act as precursors for the body's protein synthesis,
thus becoming the body's constituent proteins.
Throughout the anabolic pathway, amino acids do not
release any nitrogen catabolites or energy (Fig. II).
Figure II. The Protein Metabolism Anabolic Pathway
On the other hand, when dietary amino acids follow the
catabolic pathway, they act only as a source of
energy and not as precursors of body's proteins synthesis.
Throughout the catabolic pathway, amino acids do release
nitrogen catabolites and energy (Fig. III).
