Synthesis of amino acids and amines using an organic boron derivativesAmines and amino acids are prepared by reacting an amine, a carbonyl derivative, and an organoboron compound under mild conditions.ペタシスニコス エイ.
Derivatives of amines and amino acidsDerivatives of amines and amino acidsNovel compounds of the formula ##STR1## wherein A is methylene, ethylene or ethylidene; R.sub.1 is --C.tbd.CH or --CH═CH.sub.2 ; R. sub.2 is hydrogen or COR wherein R is hydroxy, a straight or bra...
The critically acclaimed laboratory standard, Methods in Enzymology, is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. The series contains much material ...
The importance of amino acids and biogenic amines is widely recognised in various fields, particularly in the fields of food science and nutrition. This mini-review contains a summary of my main research field that centres on aspects of Food Quality and
A great variability among samples was observed in terms of their content in free amino acids. The main biogenic amine was putrescine, followed by tyramine and histamine; however, the concentrations were below those considered as toxic in alcoholic beverages. Strong negative correlations (P...

Ammonia and amines (including amino acids) were shown tocatalyze the formation of sugars from formaldehyde andglycolaldehyde, and the subsequent conversion of sugars tocarbonyl-containing products under the conditions studied (pH5.5 and 50°C). Sterically unhindered primary amineswere better catalysts th...
Amino Acids and the Multiplication of Bacteriophage In a study of the influence of various substrates on virus reproduction and cell growth, it has been found that a number of amino acids and related compounds support both phage multiplication and cell growth, while others do neither. Thr... S...
