In enzymology, an alpha,alpha-trehalose-phosphate synthase (UDP-forming) (EC 2.4.1.15) is an enzyme that catalyzes the chemical reaction UDP-glucose + D-glucose 6-phosphate ⇌ {\displaystyle \rightleftharpoons } UDP + alpha,alpha-trehalose 6-phosphate
The University of Vic - Central University of Catalonia (UVic-UCC), is a Catalan university with premises in Vic, Manresa and Granollers.It is a privately managed institution, under public supervision through its proprietor, the Balmes University Foundation, whose chair is the Mayor of Vic. UVic-UCC is a higher education and research centre.
L-Ribulose 5-phosphate 4-epimerase catalyzes the epimerization of L-ribulose 5-phosphate to D-xylulose 5-phosphate by retro-aldol cleavage and subsequent aldol reaction.The proposed mechanism involves the abstraction of the proton from the hydroxyl group on C-4, followed by cleavage of the bond between C-3 and C-4 to give a metal-stabilized acetone enediolate and a glycolaldehyde phosphate ...
Protactinium-231 arises naturally from the decay of natural uranium-235, and artificially in nuclear reactors by the reaction 232 Th + n → 231 Th + 2n and the subsequent beta decay of 231 Th. It was once thought to be able to support a nuclear chain reaction, which could in principle be used to build nuclear weapons ; the physicist Walter ...
Its decay product, 231 Pa, gradually precipitates to the bottom, so that its concentration first increases with depth and then stays nearly constant. 231 Pa decays to 227 Ac; however, the concentration of the latter isotope does not follow the 231 Pa depth profile, but instead increases toward the sea bottom.
Paul Charles Zamecnik (November 22, 1912 – October 27, 2009) was an American scientist who played a central role in the early history of molecular biology.He was a professor of medicine at Harvard Medical School and a senior scientist at Massachusetts General Hospital.
Virgin Australia crew members were allegedly sexually assaulted and robbed in one of Fiji's nightclub areas on New Year's Day, the island country's Deputy Prime Minister Viliame Gavoka announced.
Trehalose is a nonreducing sugar formed from two glucose units joined by a 1–1 alpha bond, giving it the name α-D-gluco pyranosyl-(1→1)-α-D-gluco pyranoside. The bonding makes trehalose very resistant to acid hydrolysis , and therefore is stable in solution at high temperatures, even under acidic conditions.
