Nаme the functiоnаl grоups in the fоllowing phаrmaceuticals: Click to Show Image Description The graphic shows a skeletal chemical structure labeled “Amitiza® treatment of irritable bowel syndrome,” with four callout labels. Label a points to the upper-left portion of the structure, where a red dashed box surrounds two F atoms bonded near the left side of the ring-like section. A blue dashed box near the center-left surrounds an HO group and nearby ring bonds. Label b points to the far-right end of the long carbon chain, where a blue dashed box surrounds a C=O group bonded to OH. Label c points to the lower-left carbon chain extending from the main structure. Label d points to a red dashed box around an O atom bonded within the lower central portion of the structure. Several solid wedge and dashed wedge bonds indicate three-dimensional bond orientation, and H labels appear on two stereocenters near the middle of the structure. Line a: [APharmaA]Line b: [APharmaB]Line c: [APharmaC]Line d: [APharmaD] Click to Show Image Description The graphic shows a skeletal chemical structure labeled “Tamiflu® anti-viral,” with five callout labels. Label a points to a red dashed box around an H₂N group bonded to the upper-left side of the central structure. Label b points to a red dashed box on the right side that surrounds a C=O group, an O atom, and adjacent bonds extending to the right. Label c points to a blue dashed box around a C=C bond on the right side of the central six-membered ring. Label d points to a red dashed box around an O atom bonded to the lower part of the central ring and to a branched carbon chain below. Label e points to a blue dashed box on the lower-left side that surrounds a C=O group, an N-H group, and nearby bonds.

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]
