Nonessential amino acids
are not necessary to stimulate net muscle protein synthesis in healthy volunteers.
For most livestock species, the minimum protein requirement is determined from the animal's requirement for both the essential amino acids and the nitrogen sources needed for the manufacture of nonessential amino acids
34 amino acids Nonessential amino acids
It advises that soy protein is equal to animal proteins (making it suitable as a sole source of protein), and that whole grains, legumes, vegetables, seeds, and nuts contain both essential and nonessential amino acids
In addition to the need for essential amino acids, the chicken's diet must contain enough protein (nonspecific nitrogen sources) to allow metabolic synthesis of the nonessential amino acids
A549 cells were obtained from Health Science Research Resources Bank (Japan Health Sciences Foundation, Osaka, Japan) and grown in Earle's minimum essential medium with nonessential amino acids
, 10% fetal bovine serum, 100 U/mL penicillin, and 100 [micro]g/mL streptomycin (Gibco BRL, Life Technologies, Inc.
Dietary lysine supplementation resulted in an increase in the plasma concentrations of free lysine, and a decrease in the concentrations of threonine, tyrosine, and some nonessential amino acids
(Henry et al.
The glutamic acid and aspartic acid were dominant in the nonessential amino acids
in both sexes in all seasons, whereas lysine, leucine, and threonine were the dominant among the essential amino acids.
As a result, it is clear that all three-carbon nonessential amino acids
have a sedative function.
