and L-alanine levels in the oysters also decreased by factors of 0.59 and 0.46 relative to the control oysters at day 2.
and alanine also had relatively high CVs.
Amino analysis of cyanobacterial cultures showed that most of amino acids are present in all three strains but glycine, alanine, valine, proline, asparagine, aspartic acid
, glutamic acid and lysine were present in appreciable amounts.

For instance, the three amino acids with the highest concentrations in the different types of organic amendments were glutamic acid (5.55-6.90 mg/g), aspartic acid
(4.56-9.14 mg/g), and glycine (3.37-6.59 mg/g).
The variation found in the interassay of more than 10%, but not exceeding 15%, was observed for ornithine, alanine, valine, and aspartic acid
and was acceptable  considering that methods with pipetting, such as the one used for amino acid analysis, usually yield CVs between 10% and 15% [20, 33].
Generally, aspartic endopeptidases depend on its aspartic acid
residues for their catalytic activity .
T4 contained higher aspartic acid
(Asp), threonine (Thr), alanine (Ala), leucine (Leu), isoleucine (Ile), and phenylalanine (Phe) concentrations than the other samples (p<0.05), which can have a negative impact on the sensory quality, as high concentrations of Met, Leu, and Ile may increase the bitter taste of dry fermented sausages .
The glutamic acid was the most abundant in all meals, followed by lysine, leucine, glycine and aspartic acid
DAP in water at room temperature also phosphorylated the amino acids glycine, aspartic acid
and glutamic acid, and then helped link these molecules into short peptide chains (peptides are smaller versions of proteins).
For example, the mice exposed to nicotine, especially the males, had lower concentrations of glycine, serine, and aspartic acid
, which could weaken the addictive effect of nicotine.
(10) This effect may have been due in part to the aspartate component of the supplement, since administration of aspartic acid
(2% in drinking water) has been shown to decrease morphine dependence in rats.
