[单选题]Synthesis of fatty acids occurs in the cytoplasm, and is catalyzed by fatty acid synthase. In animals, fatty acid synthase is a homodimer, with each chain approximately 250,000 Daltons in size. The two chains are linked head to tail. All of the components of fatty acid synthase, including acyl carrier protein (ACP) and  β-ketoacyl ACP synthase, are contained within the two chains. Reactions occur in the space between the two chains, an arrangement that keeps the reactants in one place. The first round of synthesis produces a 4-carbon unit. From here, two carbons are added until the final product, palmitate is made. How many rounds does it take to make palmitate?Tj3答案窝(daanwo.com)-大学生作业答案及考资分享平台
