According to the ideal protein concept, amino acid profile is expressed relative to lysine content, because lysine is usually the first limiting amino acid and exclusively used for body protein synthesis.
A number of methods have been applied for the determination of amino acids in soil samples.

However, the team thinks its unlikely amino acids could have survived the conditions that created the meteorite, which endured higher temperatures more than 2,000 degrees Fahrenheit (over 1,100 Celsius) over a much longer period.
An artificial amino acid can provide an extra "chemical handle" on an otherwise normal molecule, says Ho Sung Cho, chief technology officer of the California biotech company Ambrx (founded in part by Schultz, who is a stockholder).
Leucine, isoleucine and valine, known as branched-chain amino acids (BCAAs), account for a fraction of the 20 amino acids from which proteins are made, but appear to have anti-ageing properties.
If in certain cases a particular amino acid is required, the production of other amino acids being produced at the same time ceases trough a complex regulatory control (Clarie, 1998).
38) Like serine and tyrosine, threonine is recognized as a proteinogenic (protein building) amino acid, (39) and is recognized for its role in the formation of collagen and elastin.
Amino acid content of microbial protein, as well as that of animal tissue and bovine milk, is shown in Table 7-1.
It has been generally accepted that there is a wide diversity in amino acid sequences and sources of antimicrobial peptides," says study co-investigator Michael Yeaman, a professor of medicine at the David Geffen School of Medicine at UCLA.
Composition based sequencing is a method for the mass spectrometrical determination of the amino acid sequence of unknown peptides, which are not necessarily listed in protein or other databases.
