Imаge Descriptiоn The structure cоnsists оf а heterocyclic ring fused with а tetrahydrothiophene ring. Here's a breakdown of its structure: Heterocyclic Ring: At the top of the molecule lies a heterocyclic five-membered ring. The top of the ring is a carbon, double-bonded to an oxygen atom to form a ketone. The next atom in the ring in both directions is a nitrogen, each with one hydrogen attached. Each of the two bottom atoms in the ring is carbon. Tetrahydrothiophene Ring: Fused to the bottom of the heterocyclic ring is a second five-membered ring, a tetrahydrothiophene ring. This ring consists of four carbon atoms, with the lowest point in the pentagon being a sulfur heteroatom. The upper two carbons of the tetrahydrothiophene ring are the same carbons as the lower two carbons of the heterocyclic ring. Valeric Acid Side Chain: Attached to one of the side-carbon atoms of the tetrahydrothiophene ring is a valeric acid side chain, which consists of a pentanoate or a deprotonated pentanoic acid.
