Answer question 4 please!!!!

2. (10 pts) With the help of the internet and your textbook, A. hand-draw the chemical structures of dipalmitoyl phosphatidyl choline, DPPC (also known as lecithin, although lecithin is a more general name and can refer to other chemical structures). B. Where is DPPC found in a cell? C. Is this a lipid, carbohydrate, protein or nucleic acid? Do not leave any " R " groups in the structure that you draw. 3. (10 pts) With the help of the internet and your textbook, hand-draw the chemical structures of the following: A. ibuprofen (What trademarked product is this used in?) B. amoxicillin (What type of agent is this?) C. diltiazem (What condition is this used to treat?) D. L-aspartyl-L-phenylalanine methyl ester (What is this chemical's trade name?) E. atorvastatin (What trademarked product is this used in?) Draw each of these structures by hand. Do not leave any " R " groups in the structure that you draw. 4. (10 pts) Using the structures you drew in questions 2 \& 3, for each of the organic functional groups listed below, which of these 6 chemicals have these bonds? (For example, alkanes, which have Carbon-carbon single bonds, as in CH2CH2, are found in: ABCDEF; all 6 have at least one section that is alkyl) (1) ester (2) amide (or peptide) (3) ether (4) amine (5) alkene (6) aromatic/benzyl (7) alcohol (8) ketone (9) aldehyde (10) thiol or mercaptan (11) phosphoryl (12) carboxylic acid (13) quaternary ammonium If any of these functional groups do not appear in the chemical structures of the 6 chemicals, draw an example chemical to illustrate this (these) functional groups.
