Unformatted text preview: 1) (12p) Convert the following measurements to the indicated units. Your answer must be in scientific fl/ B) (41)) Mark chiral carbons with asterisks C) (4p) How many stereoisomers can exist for this ' V C) (4p) How many stereoisomers can exist for this I monosaecharide 25: 3 2- Li 0 ' I D) (9p) Specifically name the three possible 3) (10p) Given the reaction and starting concentrations ofA=5O and B=25 nM and a -2.3 Arnino acids arc joined together by @condensation reactions joining an amine group to a carboxyl group on the preceding monomer xl B) hydrolysis reactions joining a carboxyl group to an amine group on the preceding monomer C) condensation reactions joining a phosphate group to a hydroxyl group on the preceding monomer XD) hydrolysis reactions joining a phosphate group to a hydroxyl group on the preceding monomer E) condensation reactions joining a hydroxyl group to a phosphate group on the preceding monomer WF) none ofthe above i t Visible light can not break the covalent bonds that are critical to life but can break bonds in other molecules. The most important feature that detennines whether visible light can break a bond is A) whether the molecule is water soluble B) whether the visible light out by the atmosphere C) ifthe atoms involved in the bond are large or small atoms C;this question is bogus. Visible light can not break covalent bonds The difference between triglycerides and sterols is that i A) Triglycerides are hydrophilic while sterols are hydrophobic ,BJ Triglycerides are used to form membranes while sterols are used as hormones @Triglycerides are hydrophobic while sterols are hydrophilic D) Triglycerides are storage molecules while sterols are used to form membranes and hormones E) none ofthe above The ability of carbon to form bonds with oxygen and nitrogen provide a property to the carbon polymer that is distinct from carbon polymers bonded with hydrogen. The polymers containing N and O provide for: A) stronger covalent bonds B) hydrophilic polymers @hydrophobic polymers...
