- Four stereoisomers exist for 3-penten-2-ol. (a) Explain how these four stereoisomers arise. (b) Draw the stereoisomer having the E configuration about the carbon-carbon double bond and the R configuration at the chiral center.arrow_forwardPGF 2a is a prostaglandin, a group of compounds that are responsible for inflammation (Section 19.6). (a) How many tetrahedral stereogenic centers does PGF 2a contain? (b) How many double bonds can exist as cis and trans isomers? (c) Considering both double bonds and tetrahedral stereogenic centers, what is the maximum number of stereoisomers that can exist for PGF20?

- a-Linolenic acid ((9Z,12Z,15Z)-octadeca-9,12,15-trienoic acid; ALA)) is a poly-unsaturated, w-3 fatty acid with 18 carbons found in many food sources. Since humans cannot synthesize fats with double bonds past carbon #9, it is "essential" and must be obtained from the diet. Hope you like salmon! If a serving of salmon contains 500.0 mg of ALA and all of it is completely oxidized via B-oxidation and the TCA, how many grams of water at room temperature can be brought to a boil using that energy? (Specific heat of water: 4.184 J/mol; heat of vaporization of water: 40.65 kJ/mol; molar mass of ATP: 507.2 g/mol; DG° of ATP hydrolysis = -30.3 kJ/mol)arrow_forward(a) Draw the products of molecular formula C3H4Cl2, including stereoisomers, formed when chlorocyclopropane is heated with Cl2. (b)Assuming that compounds that have different physical properties are separable, how many fractions would be present if the mixture of products were distilled using an efficient fractional distillation? (c) How many fractions would be optically active?arrow_forwardEleostearic acid, C18H30O2, is a rare fatty acid found in the tung oil used for finishing furniture. On ozonolysis followed by treatment with zinc, eleostearic acid furnishes one part pentanal, two parts glyoxal (OHC-CHO), and one part 9-oxononanoic acid [OHC(CH2)7CO2H].
