In intact microsomes, quercetin 3-O-α-(2″-galloyl)rhamnoside (QGR) inhibits glucose-6-phosphatase (G-6-Pase) in a concentration-dependent manner. QGR increased the G-6-Pase Km for glucose-6-phosphate without change in the Vmax. The flavonol did no

Metabolism and distribution of grasses in tropical flooded savannas in Venezuela

Autor: Norma Motta, Ernesto Medina

Publikováno v: Journal of Tropical Ecology. 6:77-89

Flooded savannas in south-west Venezuela consist of seasonal, marshy and flooded grassland communities, the distribution of which depends on soil level. Seasonal grasslands are dominated by tuft-forming, rhizomatous C4-grasses (exemplified byPaspalum

Inhibition of hepatic neoglucogenesis and glucose-6-phosphatase by aqueous extract ofBauhinia megalandra leaves

Autor: Freddy González-Mujica, Aniuska Becerra, Norma Motta

Publikováno v: Phytotherapy Research. 12:291-293

An aqueons extract of Bauhinia megalandra leaves causes a decrease of nearly 50% in the glucose production, from lactate or fructose, of rat liver slices incubated in Krebs-Ringer bicarbonate buffer supplemented with oleate-saturated albumin. In inta
