Studies on Sugar-Amino Acid Compound. III

Synthesis and structural studies of peptides containing a mannose-derived furanoid sugar amino acid.

A mannose-derived furanoid sugar amino acid (Maa) induced helical turns in peptides having repeat units of Maa(Bn(2))-Phe-Leu, which aggregated into head-to-tail duplexes in the longer oligomers.

Studies on Amino Acid Metabolism. Iii. Plasma Glycine Concentration and Hippuric Acid Formation following the Ingestion of Benzoate.

The conjugation of benzoic acid with glycine, resulting in the formation of hippuric acid, takes place in liver (1) and kidney (2). The urinary output of this conjugate after the administration of benzoate is used to measure this aspect of hepatic function (3). Theoretically, decreased hippuric acid formation may be due to hepatic and/or renal disease or to an inadequate supply of glycine. In t...

Serological Studies on Sugar

Solutions of all of the C. P. sucrose reagents of American manufacture that were tested gave reactions with Type II antipneumococcus serum. The capacity of that antiserum to react with sucrose solutions was removed by absorption with the homologous pneumococci or with Leuconostoc mesenteroides. The serological reactivity was due not to sucrose itself but to accompanying substances that could be...

Amino Acid Composion and Sugar Analysis of MCJ Lectin

Momardica charantia L.var. Jhalri (MCJ) is the member of lectins from the family Cucurbitaceae. For further characterization MCJ lectin was analyzed for amino acid identification and sugar analysis by paper chromatography in the present paper. The technique reported the presence of total 18 amino acids with large content of Serine and Glutamic acid. The same technique revealed the presence of g...
