Chemical element of metals. Cu comes from Cuprum, Fe comes from Ferrum, Ag from Argentum. The symbols were not followed by a period (full stop) as with abbreviations. Later chemical elements were also assigned unique chemical symbols, based on the name of the element, but not necessarily in English. For example, sodium has the chemical symbol 'Na' after the Latin "natrium". The same applies to "W" (wolfram) for tungsten, "Fe" (ferrum) for iron, "Hg" (hydrargyrum) for mercury, "Sn" (stannum) for tin, "K" (kalium) for potassium, "Au" (aurum) for gold, "Ag" (argentum) for silver, "Pb" (plumbum) for lead, "Cu" (cuprum) for copper, and
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
