Question

Write the accurate solution of the given question

Question- Enoyl CoA hydratase catalyzese a syn addition.

Part 1- Draw the structure of the product expected when crotonl coA (trans) CH₃CH= CHC (o)CoA is incubated with the enzyme in D2O.

Part 2- At ph=7 keq for this reaction is 16, in favor of the hydrated product, hydroxybutryl-CoA (HBC). A synthetic sample of (+-) -HBC was prepared from racemic 3- hydroxybutric.

So If 1 mM of this HBC is added to a buffer solution containing enoyl coA hydratase

i- How much crotonul-coA will be present when the enzymic reaction reaches equilibrium?

ii- How much HBC will be present at aquarium?

I want experts help to draw the structure of the product.
