Dipeptide analysis in human urine

Journal of Chromatography B: Biomedical Sciences and Applications, 1986
Fractions of dipeptides, obtained from human urine by a combination of cation-exchange chromatography, ligand-exchange chromatography and reversed-phase chromatography, were transformed into their N-heptafluorobutyryl methyl ester derivatives and then subjected to capillary gas chromatography.

Putreanine excretion in human urine

Biochimica et Biophysica Acta (BBA) - General Subjects, 1970
Abstract 1. 1. Putreanine, N -(4-aminobutyl)-3-aminopropionic acid, was detected in human urine. 2. 2. The concentration of urinary putreanine was determined using an automatic amino acid analyser. No significant differences or changes were observed between the sexes or during development and aging. 3. 3.

Conjugated Oxosteroids in Human Urine

Nature, 1964
IT has long been known that oxosteroids are excreted in human urine in conjugated form chiefly as sulphates or glucuronidates. In order to test the hypothesis that the choice of either sulphate or glucuronidate in different individuals may be wholly or partially determined by genetical factors it was necessary to devise a simple and rapid method for ...

Human Growth Hormone in Urine

The Journal of Clinical Endocrinology & Metabolism, 1971
ABSTRACT Total immunoreactive human growth hormone (IR-HGH) was measured in one or more 24 hr urine samples collected from five normal, three acromegalic, and six hypopituitary (five before and one after treatment with HGH) patients. After concentration by polyionic membrane ultrafiltration, mean levels of total IR-HGH were 79, 35, and 254 ng per 24 hr

IMMUNOASSAY OF INSULIN IN HUMAN URINE

Acta Endocrinologica, 1966
ABSTRACT The use of a sensitive immunological system has made it possible to demonstrate insulin in the urine of non diabetic and diabetic subjects with a high degree of reliability and without any preceding concentration of the urine. The 24-hour excretion in non diabetics as well as in diabetics was found to be of the same magnitude ...

The Detection of Psilocin in Human Urine

Journal of Forensic Sciences, 2001
Abstract Pharmacokinetic studies of psilocybin in humans have shown the rapid dephosphorylation of psilocybin to psilocin with further conversion to 4-hydroxy-tryptophole (4HT) and 4-hydroxyindole-3-acetic acid (4HIAA) in plasma. Our study shows that psilocin also undergoes conjugation and can be found in the urine as the psilocin ...

Determination of ophidine in human urine

Journal of Chromatography B: Biomedical Sciences and Applications, 1982
Ophidine (beta-alanyl-3-methylhistidine) was first detected in the urine of two patients and later in two members of the laboratory staff loaded with whale meat, by column chromatography, high-voltage paper electrophoresis and two-dimensional paper chromatography. The ophidine peak was detected between homocarnosine and dimethylarginine using a lithium

Tryptophane Metabolites in Human Urine

Nature, 1953
I HAVE already reported1 that some human urine specimens made strongly alkaline yield distillates presenting spectroscopic and polarographic properties of o-aminoacetophenone. This was interpreted as indicating the presence of kynurenine in human urine, since (1) o-aminoacetophenone is not present in untreated urine, and (2) no substance other than ...
