2. 3 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? 4 C. Is this a lipid, carbohydrate, protein or nucleic acid? Do not leave any "R" groups in the structure that you draw. 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. Using the structures you drew in questions 2 & 3, for each of the organic functional groups listed below,…

Draw a schematic of the chemical structure of the Leu-Tyr-Met-Lys tetrapeptide, with the correct ionization at neutral pH (pH 7). Also, give an estimate the pl of this tetrapeptide (you are given that the pKa of any acidic R group is 4, the pKa of any basic R group is 11.5, and the pKa of the α-COOH is 2, and the a-NH3 is 9.5). Provide rationale!

Titration of alanine by a strong base, for example NaOH, reveals two pk's. Which is the titration reaction occurring at pK1 (pK1 = %3D 2.34)? O-NH2 + COH →-NH + H2O O-COOH + OH →-CO + H20 -COOH + -NH2 → -COO" + -NH2+ -CoO +-NH2* → -COOH +-NH2 O -NH3* + OH →-NH2 + H2O
