amide, any member of either of two classes of nitrogen-containing compounds related to ammonia and amines. The covalent amides are neutral or very weakly acidic substances formed by replacement of the hydroxyl group (OH) of an acid by an amino group (NR2, in which R may represent a hydroge...
Theoretical study on the reaction mechanism for the hydrolysis of esters and amides under acidic conditions The mechanisms underlying the hydrolysis of methyl acetate and acetamide under acidic conditions were investigated using the MP2/6-311+G(d,p)//MP2/6-31+G(d... K Hori,Y Ikenaga,K Arat...
ZrO2 was demonstrated to be applicable to the hydrolysis of amide bonds: dipeptides with acidic or basic side chain into amino acids; small organic amides into both amines and carboxylic acids with their equivalent amounts; and nylon 6 into 蔚-caprolactam and 蔚-aminocaproic acid.Catalysis Science...
and the large number of functional groups that can undergo hydrolysis. Hydrolysis generally occurs via an acid- or base-catalyzed mechanism but can also occur under neutral conditions where water can act as abase. The carbonyl function of esters,lactones,amides,lactams,carbamates, andimidesare susce...
In the basis pH region, furosemide hydrolysis is extremely slow. Using the Arrhenius parameters obtained from the studies, furosemide would have a half-life of 178 min under physiological conditions in the stomach of pH 1.0 and temperature of 37.degree. C....
to form a ‘wood solution’ at 329-367oC at short reaction times (0.7-2 s). The ‘wood solution’ can be rapidly (ca. 15 s) hydrolyzed to sugars/sugar oligomers under homogeneous conditions. The patent is the latest development in Professor Fang’s 23-year effort in the study of bioma...
Presents a method for selective hydrolysis of amides in the presence of esters with copper ion/gloxal in aqueous medium. Selective hydrolysis of carboxylic esters in the presence of less reactive amide group under controlled alkaline or acidic conditions; Underutilization of amides due to non...
Under a Creative Commons license open accessHighlights Abstract Calcium binding to peptides formed by hydrolysis of whey proteins during digestion is important for calcium uptake in the intestines and affects the antioxidant function of the peptides. For the two dipeptides, Gly-Tyr and Tyr-Gly, pot...
