Measurement of rates of cholesterol synthesis using tritiated water.
Rates of sterol synthesis in various tissues commonly are assessed by assaying levels of 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase on isolated microsomes or by measuring the rates of incorporation of various 14C-labeled substrates or [3H]water into cholesterol by whole cell preparations in vitro or by the tissues of the whole animal in vivo. While measurement of activities of HMG-CoA r...
متن کاملPhotosynthate transport using tritiated water.
The exchange of HTO with aerial portions of the soybean was studied under a variety of conditions. When fed to a lone leaf or leaflet in a saturated air atmosphere (all other leaves and the growing point having been excised), the HTO profile virtually ceases at a distance of 2 cm from the feeding chamber in the photosynthetic plant, but is greater and more extensive in the unilluminated plant. ...
متن کاملMeasurement of cholesterol biosynthesis in vivo with tritiated water.
The determination of the rate of cholesterogenesis has usually involved either the measurement of the incorporation of a radiolabelled substrate, such as acetate, or the assay of the enzyme /I-hydroxy-p-methylglutaryl-CoA reductase (EC 1.1.1.34), commonly believed to be rate-limiting. However, the use of acetate is of doubtful physiological relevance, and the size and rate of turnover of the fr...
متن کاملMeasurement of Protein Degradation in Leaves of Zea mays Using [H]Acetic Anhydride and Tritiated Water.
The rate of protein degradation in Zea mays leaves has been estimated by using tritiated water and [(3)H]acetic anhydride as the labeling agents. Both methods circumvent many of the problems usually associated with measuring protein degradation in plants. The half-life of ribulose-1,5-bisphosphate carboxylase protein in second leaves of 13-day-old seedlings under continuous light was found to b...
متن کاملBody water estimation in the newborn using tritiated water.
Of all the substances used for the estimation in vivo of total body water content, the most attractive are the isotopes of hydrogen, since they enter into all the metabolic processes involving water and have no selective secretion or storage. Deuterium was the first substance used for body water estimation in vivo (Hevesy and Hofer, 1934) and is preferable to tritium because it is not radioacti...
