Four types of amino acid related compounds were examined on their plant growth-regulating activity. These compounds were N-acylamino acids (N-acyl), N-alkylamino acids (N-alkyl), amino acid higher alkyl esters (ester) and amino acid higher alkyl amides (amide). Every compound, when the ...

Studies on the peptides, free amino acids and certain related compounds isolated from ox bone The acid-soluble nitrogenous components of ox bone were fractionated by gel filtration and ion-exchange chromatography. The overall amino acid composition and the relative proportions of free and peptide-boun...
The meaning of AMINO ACID is an amphoteric organic acid containing the amino group NH2; especially : any of the various amino acids having the amino group in the alpha position that are the chief components of proteins and are synthesized by living cells
aThe analysis of free amino acid and volatile compounds were conducted to understand the changes in taste and flavor of five samples which were solid fermented. 对游离氨基酸的分析和挥发性化合物进行了解在是被发酵的固体五个样品上的口味和味道的变化。 [translate] ...
Amino acidsarenatural compoundscomposed of amine (–NH2) andcarboxylic acid(–COOH) functional groups, linked to the same carbon atom (Figure 1.1). Different amino acids have a different and specific side chain linked to this exact carbon. There are more than 500 amino acids identified, some ...
After the removal of amino groups, the carbon skeletons of amino acids undergo oxidation to compounds that can enter the citric acid cycle for oxidation to CO2 and H20. The reactions of these pathways require several cofactors, including tetrahydrofolate and S-adenosylmethionine in one-carbon transf...
