The open-chain structure of a ketotriose has to be drawn and the optical activity also has to be explained. Concept introduction: Monosaccharides are organic molecules that have a general formula of ( C H 2 O ) n , in which the open chain of hydrocarbons that carries alcohol functional groups on all but one carbon. The remaining carbon may carry an aldehyde group (in the case of an aldose) or a ketone group (in the case of ketoses). Ketotriose is a three carbon sugar in which a keto group is present. Optical activity of a molecule is the interaction between molecule and plane-polarized light. Molecule having asymmetric center shows optical activity except mesocompounds ( Mesocompounds have a plane of symmetry in there structure.). Asymmetric center is a stereocenter which arises to hydrocarbons if the carbon is bonded to four different groups.

The enzyme lactate dehydrogenase (LDH) catalyzes the conversion of pyruvate to lactatein skeletal muscle cells using NAD/NADH during anaerobic “balanced” fermentation.Answer the following questions about this reaction. (a) Write out the two reductive half reactions and indicate the E ̊' for each half reaction. Write out the full balanced reaction for the pyruvate to lactate rxn and indicate the ∆E ̊' for the reaction. (b) What is the free energy change under standard state conditions for thisreaction? Which direction is spontaneous?(c) Assume that in skeletal muscle cells the ratio of [NAD+] to [NADH] is 100, and that the[pyruvate] = 0.40 mM and [lactate] = 4.0 mM. What is the free energy change (∆G')for the conversion of pyruvate to lactate? Indicate the direction in which the reactionis spontaneous under these cellular conditions.

Why did the authors worry about the temperature-dependent solubility of the carriers in thebilayer? How did the authors determine whether the effect of freezing the lipid bilayer wasto decrease the solubility of the carriers (nonactin and valinomycin) or whether the effectwas to impair their ability to diffuse through the membrane (decrease their mobility)?

Kranse et. al. measured the temperature dependence of conductance using membranescontaining the phospholipids glyceryl dipalmitate and glyceryl distearate. Describe themodifications in membrane content that you would employ to: (a) shift the temperature of the phase transition (b) make the ion conductance curve for valinomycin andnonactin more like that of gramicidin
