The stereochemistry of palmitoyl-ACP Delta(4) desaturase-mediated dehydrogenation has been examined by tracking the fate of deuterium atoms located on stereospecifically monodeuterated substrates-(4S)- and (4R)-[4-(2)H(1)]-palmitoyl-ACP and (5S)- and (5R)-[5-(2)H(1)]-palmitoyl-ACP. It was found that the introduction of the (Z)-double bond between C-4 and C-5 of a palmitoyl substrate occurs with pro-R

3-Hydroxy fattyacids have attracted the interest of researchers, since some of them may interact with free fattyacid receptors more effectively than their non-hydroxylated counterparts and their determination in plasma provides diagnostic information regarding mitochondrial deficiency. We present here the development of a convenient and general methodology for the asymmetric synthesis of 3-hydroxy
