Studies in Protein Metabolism
There is no doubt that animals can synthesize certain amino acids, the ultimate source of the nitrogen being that of the food protein. This process probably occurs under normal conditions, as the average composition of food proteins is never the same as that of the body proteins into which they have to be converted. According to the generally accepted theory, amino acid synthesis in the animal ...
متن کاملStudies on myocardial metabolism of protein and amino acids by the use of C14-labelled substrates.
(1) In order to study the relationship between the energy metabolism via TCA cycle and amino acid metabolism as well as protein synthesis, C14-labelled substrates were used for tracer experiment . (2) Considerable C14O2 formation was noted from carbohydrates such as acetate-1-C14, pyruvate-1-C14, and pyruvate-3-C14, while a smaller amount of C14O2 was produced from amino acids such as glycine1-...
متن کاملPlasma Protein Metabolism—electrophoretic Studies
The findings on electrophoretic analysis of plasma proteins during many weeks of low protein feeding in dogs accord in general with those of chemical analysis as concerns the alterations in plasma albumin and globulin concentrations. Long continued restriction of dietary protein results in decreased albumin levels while plasma globulin concentrations remain essentially normal. The degree of dep...
متن کاملStudies on Calciferol Metabolism
The administration of cholecalciferol (vitamin D3) (CC) to rachitic chicks results in the production of two major polar metabolites, 25-hydroxycholecalciferol (25-OH-CC) and 1,25-dihydroxycholecalciferol (1,25-diOH-CC), and a number of other minor metabolites. Eighteen hours after a physiological dose (0.65 mnoles) of radioactive cholecalciferol, 80% of the radioactivity in the target intestine...
متن کاملStudies on Testosterone Metabolism
Testosterone glucuronide (unlabeled and labeled) was synthesized and injected into three normal men, one pregnant woman, and one child. In addition to testosterone glucuronide itself, several urinary metabolites were isolated. Only 5&androstane steroids were obtained. More 5/!Landrostane-3or, 17/3-diol than Sfl-androsterone was found. Meanwhile, a testosterone tracer gave Sa-metabolites, and mo...
