Whаt mаjоr clаss оf biоmolecule is in each of these pharmaceuticals or consumer products? If a lipid, specify the subclass. Click to Show Image Description The structure is labeled “levodopa” and shows a six-carbon benzene ring with two HO groups bonded to adjacent carbons on the left side of the ring. A carbon chain extends from the right side of the ring to a carbon shown with a solid wedge bond to NH₂ and a single bond to a carbonyl carbon. The carbonyl carbon is double bonded to O and single bonded to OH. [classA] Click to Show Image Description The structure is labeled “Nasonex” and shows a multi-ring skeletal chemical structure with fused rings in the center and lower left. An HO group is bonded to the upper-left part of the fused-ring system. Cl appears on a lower central ring carbon and again at the end of a short side chain on the upper right. The structure also includes two C=O groups, one on the lower-left ring and one in the upper-right side group, plus a five-membered oxygen-containing ring attached near the top. Solid wedge and dashed wedge bonds indicate three-dimensional bond orientation. [ClassB] Click to Show Image Description The structure is labeled “δ-cadinene - oil of juniper” and shows two fused six-carbon rings sharing a central bond. A C=C bond appears on the upper-left side of the left ring. Solid wedge bonds extend to one-carbon branches on the lower-left ring carbon and the upper ring junction. Another solid wedge extends from the lower ring junction to a branched carbon group with two one-carbon ends. [ClassC] Click to Show Image Description The structure is labeled “Didanosine (phosphate) treatment of HIV.” A five-membered ring containing one O atom is connected on the left to a phosphate group and on the right to a fused two-ring structure containing several N atoms. The phosphate group shows P double bonded to O, single bonded to two OH groups, and single bonded through O to the five-membered ring. The fused ring system includes a C=O group at the upper right and an N-H group at the lower right. Solid wedge bonds indicate three-dimensional bond orientation at two points on the five-membered ring. [ClassD]
