WebNotice that the structure of this carrier group (called phosphopantetheine) is identical to the region of coenzyme A (structure shown earlier in this section) near the thiol group. Once attached to the ACP, the two-carbon acetyl group condenses with another acyl group (which is also attached to its own ACP), and the fatty acid chain begins to grow. WebAcetal: A functional group in which carbon is attached by single bonds to two ether oxygen and two carbons (or hydrogens). A thioacetal has two sulfur atoms in place of an acetal's …
WebMay 14, 2024 · During each turn, a 2-carbon acetyl group combines with oxaloacetate and two carbon atoms are removed during the cycle as CO2. Oxaloacetate is regenerated at the end of the cycle, while four pairs of hydrogen atoms are removed from four of the Krebs cycle intermediate metabolites by enzymatic dehydrogenation.
