Thioacetolysis
In organosulfur chemistry, thioacetals are the sulfur (thio-) analogues of acetals (R−CH(−OR)2). There are two classes: the less-common monothioacetals, with the formula R−CH(−OR')−SR", and the dithioacetals, with the formula R−CH(−SR')2 (symmetric dithioacetals) or R−CH(−SR')−SR" (asymmetric dithioacetals). Web3-Oxoacyl-CoA thiolase occurs in 3 forms: 2 mitochondrial enzymes, 1 specific for acetoacetyl-CoA and 1 specific for 3-oxoacyl-CoA derivatives of higher chain length and 1 …
