Applicability of an enzymatic quantitation of methylmalonic, propionic, and acetic acids in normal and megaloblastic states.
A rapid sensitive spectrophotometric assay for the measurement of methylmalonic and propionic acids in urine is described. The assay is based upon the quantitation of propionic acid using acetyl coenzyme A synthetase isolated from baker's yeast. This enzyme is highly specific for acetate and propionate, and acetate interference is eliminated by conversion to citrate. Methylmalonic acid was assa...
متن کاملThe Utilization of Acetic, Propionic and Butyric Acids by Growing Heifers.
Differing efficiencies of utilization of acetic, propionic and butyric acids in both fasting and fattening sheep have been demonstrated by Blaxter and his colleagues (Armstrong & Blaxter, 1957a, b ; Armstrong, Blaxter & Graham, 1957). In fasting sheep, when the acids were given singly as the sole source of energy, the heat increment with acetic acid (41 yo of the energy of the metabolized acid)...
متن کاملMeasurement of the rates of production of acetic, propionic and butyric acids in the rumen of sheep.
Numerous studies have been made of the quantitative aspects of the production of volatile fatty acids (VFA) in the rumen, and have been reviewed by Rook (1964), Warner (1964) and Annison (1965). Interest in rumen VFA production has recently been intensified because of the findings correlating body-weight increases with the concentration of rumen VFA in lambs on various pastures (Johns, Ulyatt &...
متن کاملThe mechanism of absorption from the rumen as exemplified by the behaviour of acetic, propionic and butyric acids.
Absorption of the lower fatty acids occurs directly from the rumen of sheep, in which organ they are produced as a result of bacterial fermentation. Previous work on this subject, in which the pH of the rumen was not controlled (Barcroft, McAnally & Phillipson, 1944), showed that: (a) The quantity of acid absorbed is substantial. (b) The rate of absorption from the normally filled rumen bears n...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
