Excretion of l-malic acid in the chicken

open access: yesAmerican Journal of Physiology-Legacy Content, 1960
The mechanism of excretion of malic acid has been studied during infusion of sodium salts of l-malic acid, succinic acid and malonic acid in the chicken. Infusion of preformed l-malate results in its filtration and reabsorption in the nephron; no renal tubular secretion is seen under these circumstances. However, when succinate is infused in the renal

Preservation of lipids with malic acid

Journal of the American Oil Chemists' Society, 1970
AbstractThis paper deals with an evaluation of malic acid in a number of different lipids of animal and vegetable origin under comparable conditions. An Active Oxygen Method was used, with citric acid as the standard of comparison. In most cases, the performance of the acids was determined in the presence and absence of added iron salts and ...

Comparative study of carboxylic acid adsorption on calcite: l-malic acid, d-malic acid and succinic acid

Carbonates and Evaporites, 2018
Succinic acid and l-malic acid are known to affect calcite dissolution/crystallization due to their tendency to adsorb on calcite’s surface. Taking into account the structural similarity among succinic acid, l-malic acid, and d-malic acid, a comparative study of their adsorption behavior on calcite was investigated for clarifying their adsorption ...

D-Malic acid production from DL-malic acid by microbial assimilation of L-malic acd: Screening of microrganism

Biotechnology Techniques, 1993
Several microorganisms including Pseudomonas fluorescens, Ps. putida, Bacillus megaterium, Acinetobacter Iwofii, Klebsiella oxytoca, K. pneumoniae, Serratia rubidaea and Bulleromyces albus were selected for the ability to assimilate specifically L-malic acid. D-Malic acid with high optical purity (>90%) was obtained from the culture broth.

Structures of l-lactic acid chloralide, d-malic acid chloralide and l-malic acid chloralide

Journal of Molecular Structure, 1997
Abstract The crystal and molecular structures of l -lactic acid chloralide and l -malic acid chloralide have been determined by X-ray diffraction methods. l -lactic acid chloralide crystallises in the monoclinic space group, p2 1 , a =7.650 (3), b =5.856 (2), c =9.808 (4) ′, β =99.64 (3)°, Z =2.
