groups, -COOH. The alpha-amino acids RCH(NH2)COOH (where R is either hydrogen or an organic group) are the component molecules of proteins; some can be synthesized in the body (nonessential amino acids) and others cannot and are thus essential components of the diet (essential amino acids...
Inprotein: The amino acid composition of proteins …consist of long chains of α-amino (alpha amino) acids. The general structure of α-amino acids is shown in . The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group (―NH2); the α-carbon ...
-Amino acids are prepared by catalytically hydrolyzing a hydantoin compound of the formula, ##STR1## wherein R.sub.1 and R.sub.2 are individually hydrogen or an unsubstituted or substituted alkyl, cycloalkyl, alkenyl, aryl or aralkyl group, in the presence of imidazole or a derivative ...
Serum levels of alpha aminoacid nitrogen and free aminoacids were studied in forty-two newborns, their mothers and in ten non-pregnant healthy women. The alpha aminoacid nitrogen was raised in the cord and maternal sera as compared with the value in the sera of non-pregnant women. The highe...

This invention relates to new compositions of matter for use in treating wrinkling of the human skin. The compositions comprise, as an essential ingredient therein, at least one N-acylate, by butyric acid, of an alpha-amino acid or a salt of said acylate with an inorganic, organic or biolog...
General Method for Reaction with α-Aminoacids In a 100 mL round bottom flask, 0.2 g (0.69 mmol) of 3-isopropoxy-1-(2-methyl-4,5-dinitroimidazol-1-yl)propan-2-ol (2), 2.07 mmol of α-aminoacid and 10 mL of 75% ethanol was mixed. The mixture was heated to reflux in a water...
