Fractionation and properties of glutamic oxalacetic transaminase.
Because of the general nature of the transamination reaction (1, 2), a study of the kinetics and mechanism of reaction seemed of interest. Preliminary studies of this nature have already appeared (3-5). However, these studies were carried out with crude extracts or resolved enzyme systems. In order to conduct a critical kinetic study as well as a study of the mechanism of reaction, large amount...
متن کاملAutomated Determination of Serum Glutamic Oxalacetic and Glutamic Pyruvic Transaminase.
The determination of serum glutamic oxalacetic and glutamic pyruvic transaminase has been simplified by the use of automated analysis. The flow diagrams, concentration of reagents, and calculation of the color unit in terms of the Karmen unit are shown for 2,4-dinitrophenylhydrazine and 6-benzamido-4-methoxy-m -toluidine diazonium chloride as the reacting dyes. Advantages of both methods are co...
متن کاملMicro determination of glutamic-oxalacetic transaminase in blood serum.
ARGE INCREASES in glutamic-oxalacetic transaminase (GOT) activity in blood serum have been reported for patients suffering from heart or liver tissue damage. The determination of this enzyme as described by Karmen (1) and modified by Steinberg, Baldwin, and Ostrow (2) couples the transaminase reaction with the malic dehydrogenase reaction wherein the disappearance of added reduced diphosphopyri...
متن کاملSerum glutamic oxalacetic transaminase levels in diphtheritic myocarditis.
DIPHTHERITIC MYOCARDITIS BY E. CHESLER From the Johannesburg Fever Hospital, Johannesburg Received July 29, 1957 Serum glutamic oxalacetic transaminase (S.G.O.T.) is normally present in human serum, skeletal muscle, brain, liver, kidney, testis, and lung. Its highest concentration, however, is in cardiac muscle. Elevated S.G.O.T. levels occur with active dissolution of the tissues containing th...
متن کاملChanges in plasma volatile fatty acids in response to weaning and feed intake in young calves.
Effects of weaning age on plasma VFA were examined using 16 Holstein heifer calves. Animals entered the study at 6 +/- 3.5 d of age and were fed 1.8 kg milk twice daily to 28 (early weaning) or 56 d (late weaning) and a commercial pelleted calf starter from 0 (early) or 28 (late) d. Blood was sampled once weekly for 14 wk. Total blood concentrations of VFA, acetate, propionate, and butyrate wer...
