detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Transaminase activity in human blood.
Enzymatic transamination consists of the enzyme catalyzed reversible transfer of the alpha amino nitrogen of an amino acid to an alpha-keto acid with the synthesis of a second amino acid and a second alpha-keto acid. Enzymes catalyzing different transamination reactions are found widely distributed in animal tissues and have been shown to change in activity in some tissues during disease (1-3)....
متن کاملTransaminase Activity in Neurospora crassa
It is now believed that the amino groups of isoleucine and valine are accepted by their respective carbon chains during biosynthesis via a transamination. Most of the evidence for this hypothesis has been derived from experiments on isoleucineless and valineless mutants of Escherichia coli and Neurospora crassu (l-4). It is not positively established whether this transamination step can be medi...
متن کاملTransaminase activity after codeine administration.
THE quantitative and serial changes that occur in serum glutamic-oxaloacetic transaminase (SGOT) activity during the course of a myocardial infarction are well recognized. Changes in SGOT activity have been observed in other diseases such as hepatitis and pancreatitis (Wroblewski and LaDue, '955; Chinsky, Shmagranoff and Sherry, 1956) and after the administration of drugs such as chlorpromazine...
متن کاملInhibition of tyrosine transaminase activity by norepinephrine.
The neurotransmitter, norepinephrine, and structurally related primary catecholamines inhibited rat hepatic tyrosine transaminase activity (L-tyrosine:2-oxoglutarate aminotransferase, EC 2.6.1.5) in vitro. The inhibition was competitive with pyridoxal 5’-phosphate cofactor and an “apparent” I& of 4.0 x 10-e M was determined. (The “apparent” K,,, was 6.6 X 10-T M.) Those amines which were associ...
