Further work indicated that alkaline hydrolysates also contained greater amounts of glycine. These results suggested that, under the conditions commonly employed for the hydrolysis of proteins with alkali, glycine and 伪-amino- n -butyric acid are formed by decomposition of other amino-acids.

Alkaline hydrothermal systems have received considerable attention as candidates for the origin and evolution of life on the primitive Earth. Nevertheless, sufficient information has not yet been obtained for the thermodynamic properties of amino acids, which are necessary components for life, at high te...
Alkaline hydrolysis of of 5,6-dihydro-4H-1,3-oxazines is a convenient method via which to obtain the corresponding 1,3-amino alcohols or their N-acyl derivatives <1996CC1629>. The yields are usually excellent, as in the transformation of 2,4,4-trimethyl-5,6-dihydro-4H-1,3-oxazine 130...
Alkaline Hydrolysis of Optically Active p-Nitrophenyl a-Methoxyphenylacetate and p-Nitrophenyl Esters of N-Benzyloxycarbonyl a-Amino Acids in Aqueous N, N-... The hydrolysis of d- and l-p-nitrophenyl a-methoxyphenylacetate and p-nitrophenyl esters of N-benzyloxycarbonyl a-amino acid catalyzed by ...
Hydrolysis of methamidophos readily occurs in neutral or alkaline conditions, with half-lives of 660, 5 and 3 days at pH 4, 7 and 9, respectively. 甲胺磷的水解易发生在中性或碱性条件下,在pH值分别为4、7和9的溶液中,半衰期分别为660天、5天和3天。 UN-2 The FDA should therefore require...
IMPROVED PROCESSES FOR THE ISOLATION OF 4-AMINO-3-CHLORO-6-(4-CHLORO-2-FLUORO-3-METHOXYPHENYL)PYRIDINE-2-CARBOXYLIC ACID carboxylic acids are conveniently prepared by the alkaline hydrolysis of either the corresponding esters or the corresponding protected N-acetylated esters. The... MVM Emonds,RC...
The hydrolysis of maleimide has been investigated in the pH range 8.5–14. Polarographic limiting currents were well-defined, so that the bulk concentration of reactant during reduction could be clearly followed as a function of time. Logarithmic analysis of derived data indicated an arrest in the...
Alkaline phosphatases are a family of enzymes which catalyze the hydrolysis of phosphate esters, releasing inorganic phosphate, at alkaline pH levels. In addition to their production in the liver, alkaline phosphatase isoenzymes are formed in the bone, intestine, and placenta. Serum alkaline phosphatas...

Amino acids can also be released by hydrolysis of HCN oligomers that form by the self-condensation of hydrogen cyanide in aqueous solution [23]. Such reactions do not require alkaline conditions. Purines are formed from HCN via two routes. One route is via the HCN oligomers that also forms ...
