Period 5 element with most production coming from the Xikuangshan Mine in Hunan. Antimony compounds are prominent additives for chlorine and bromine containing fire retardants found in many commercial and domestic products. The largest application for metallic antimony is as alloying material for lead and tin. It improves the properties of the alloys which are used as in solders, bullets and ball bearings. An emerging application is the use of antimony in microelectronics. Tellurium is a chemical element that has the symbol Te and atomic number 52. A brittle, mildly toxic, rare, silver-white metalloid which looks similar to tin, tellurium is chemically related
Sn-glycerol-1-phosphate dehydrogenase Sn-glycerol-1-phosphate dehydrogenase In enzymology, a "sn"-glycerol-1-phosphate dehydrogenase () is an enzyme that catalyzes the chemical reaction The 3 substrates of this enzyme are sn-glycerol 1-phosphate, NAD, and NADP, whereas its 4 products are glycerone phosphate, NADH, NADPH, and H. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD or NADP as acceptor. The systematic name of this enzyme class is sn-glycerol-1-phosphate:NAD(P) 2-oxidoreductase. This enzyme is also called glycerol-1-phosphate dehydrogenase [NAD(P)]. G-1-P dehydrogenase is responsible for the formation of "sn"-glycerol 1-phosphate, the backbone of the membrane phospholipids of Archaea. The gene
