Question

Please help me answer these 4 questions! Thankyou!

Select the initial precursor that would form from hexanoyl-CoA serving as the primer and three moles of malony-COA used as the extender. Unlike a typical fatty acid biosynthesis, there are no reduction steps and no dehydration steps. FAS Enter Your Answer: @ A В In various ducks special fatty acids are produced to make special water resistant esters. One such acid is the compound, 2,4,6-trimethylnonanoic acid. Use this compound for problems 24 2.4,6-trimethyinonanoic ackd The biosynthetic pathway for 2,4,6-trimethylnonanoic acid is thought to be similar to the normal FAS fatty acid synthase pathway discussed in class, but a different primer compound is used and a different compound is used as the extenders on 2 Which of the above compounds is used as the primer compound in the biosynthesis?

Answer 1

1. A ( it is a polyketide, comprised of 12 C) which is formed by the reaction of hexanoyl coA and malonyl coA.
