RAPID DETERMINATION OF n-OCTANOIC ACID

C octanoic acid breath test

Although scintigraphy, a non-invasive procedure, is usually considered to be the reference technique for measuring gastric emptying in humans, several drawbacks limit its application in routine practice. Expensive equipment is required and access to a nuclear medicine department, and the use of radioactive isotopes (generally Tc and In) can produce low but significant irradiation. It is diYcult...

The Regulation of Ketogenesis from Octanoic Acid

The regulation of ketogenesis in the rat has been studied both in uiuo and in the isolated perfused liver with octanoic acid as substrate. This fatty acid, which is not utilized directly for triglyceride synthesis, was chosen in order to investigate the events that govern the metabolism of fatty acids subsequent to the (?-oxidation process. Experiments in viuo established that for any given loa...

THE SYNTHESIS , SOME DERIVATIVES , AND THE METABOLISM OF ( Y , r - DIKETO - n - OCTANOIC ACID

Bullfrog ghrelin is modified by n-octanoic acid at its third threonine residue.

We have identified the amphibian ghrelin from the stomach of the bullfrog. We also examined growth hormone (GH)-releasing activity of this novel peptide in both the rat and bullfrog. The three forms of ghrelin identified, each comprised of 27 or 28 amino acids, possessed 29% sequence identity to the mammalian ghrelins. A unique threonine at amino acid position 3 (Thr(3)) in bullfrog ghrelin dif...

rapid and simple determination of plasma amino acid ratio

in recent years considerable interest has been focused on the plasma amino acid patterns as a possible index of protein malnutrition, in children. thus a change in the ratio of non-essential to essential amino acids is considered to be significant in the development of protein malnutrition. the present paper reports a simplified and rapid chromatographic procedure for the determination of this ...
