The uptake of D-araboascorbic acid (D-isoascorbic acid) by guinea-pig tissues.
I. Guinea-pigs on a low, controlled intake of ascorbic acid (0.3 mg/Ioo g body-weight) were given daily an oral supplement of L-ascorbic acid (AA) or of D-isoascorbic acid (isoAA) (both 1.5 mg/Ioo g body-weight). The AA was deposited in the tissues, the isoAA was not. 2. Intramuscularly administered isoAA was deposited in the tissues but not to the same extent as equivalent amounts of intramusc...
متن کاملQuantitative Separation of Radioactive Sterols and Bile Acids in Human Faeces.
A method is described for the quantitative separation of radioactive bile acids and neutral sterols in human faeces on a potassium hydroxide-treated silicic acid column. Results obtained with faecal extracts containing metabolites derived from radioactive cholesterol, cholic acid, and chenodeoxycholic acid show that the efficiency of extraction is at least 96% and that mutual contamination betw...
متن کاملQuantitative assay of conjugated and free bile acids as heptafluorobutyrate derivatives by gas-liquid chromatography.
Quantitative analyses of individual bile acids in biological samples are limited by the lengthy multistep preparations necessary. Using heptafluorobutyric acid anhydride in pyridine as derivatizing agent, we reduced several steps to one. Bile acids and their glycine and taurine conjugates form stable heptafluorobutyrate derivatives, climinating the need for deconjugation and preparation of meth...
متن کاملAn enantioselective fluorescence sensing assay for quantitative analysis of chiral carboxylic acids and amino acid derivatives.
A chiral 1,8-diacridylnaphthalene-derived fluorosensor exhibiting a C(2)-symmetric cleft designed for stereoselective interactions with hydrogen bond donors has been used for the determination of both concentration and enantiomeric composition of carboxylic acids and amino acid derivatives.
