Explain your choice. Draw the structure of guanosine. Number the carbon atoms in the monosaccharide. Classify theÃ‚Â? compound as a ribonucleoside or a deoxyribonucleoside. What is the difference between a vasodilator and a bronchodilator? Give an example of a drug that fits each category. Sample questions asked in general, organic, and biological chemistry: A commercial mouthwash contains 4.3 g of ethanol and 0.021 g of antiseptic in each 30.-mL portion. Calculate the weight/volume percent concentration of each component. (a) In what way(s) is the conversion of pyruvate to acetyl CoA similar to the conversion of pyruvate to ethanol? (b) In what way(s) are the two processes different? Draw the structures for the four sodium salts of the carboxylic acids in Problem 17.63, formed by treating each of these carboxylic acids with NaOH. Give the IUPAC name for each sodium salt. Sample questions asked in general, organic, and biological chemistry: Draw Lewis structures for CCl 4 and C 2 Cl 4 . Give the molecular shape around each carbon atom. Explain why the carbon atoms in the two molecules have different shapes. Draw the structure of a dinucleotide formed by joining the 3'-OH group of dTMP to the 5'-phosphate in dGMP. A mammogram is an X-ray of the breast. Why does an X-ray technician leave the room or go behind a shield when a mammogram is performed on a patient? Sample questions asked in general, organic, and biological chemistry: A sample of nitrogen gas contains 5.0 mol in a volume of 3.5 L. Calculate the new volume of the container if the pressure and temperature are kept constant but the number of moles of nitrogen is changed to each of the following values:(a) 2.5 mol;(b) 3.65 mol;(c) 21.5 mol. Wilson?s disease is an inherited defect in copper metabolism in which copper accumulates in tissues, causing neurological problems and liver disease. The disease can be treated with compounds that bind to copper and thus remove it from the tissues, (a) How many protons and electrons are found in a neutral copper atom? (b) How many electrons and protons are found in the Cu + cation? (c) How many electrons and protons are found in the Cu 2+ cation? (d) Zinc acetate inhibits copper absorption and so it is used to treat Wilson?s disease. What is the structure of zinc acetate? Using the balanced equation for fermentation written in Sample Problem 5.12, answer the following questions. a. How many grams of ethanol are formed from 0.55 mol of glucose? b. How many grams of CO 2 are formed from 0.25 mol of glucose? c. How many grams of glucose are needed to form 1.0 mol of ethanol? Consider the following four types of compounds:  fatty acids;  soaps;  waxes;  triacylglycerols. For each type of compound: (a) give the general structure; (b) draw the structure of a specific example; (c) label the compound as water soluble or water insoluble; (d) label the compound as soluble or insoluble in the organic solvent hexane [CH 3 (CH 2 ) 4 CH3].
