On the nonexistence of trivalent carbon

WebMalic enzyme (ME) from chicken liver (EC 1.1.1.40) is an enzyme that catalyzes the decarboxylation of malate into pyruvate and CO 2 and the reverse reaction that introduces CO 2 as a carboxy-group to pyruvate to form malate via oxaloacetate in the presence of natural co-enzyme NADP + /NADPH. http://www.chem.ucla.edu/harding/IGOC/M/monovalent.html
