. Provide an explanation for the fact that a-D-mannose is more stable than B-D-mannose, whereas the opposite is true for glucose.

Aside from asymmetric hydrogenation (Section 29.4), various more strategies for the production of optically active amino acids are currently accessible. How may a process like the Strecker synthesis be modified to produce chiral amino acids?

None

Lipid bilayers comprising high concentrations of gangliosides are very rare. Which of the following explanation is/are true? . Please note, there could be more than one answer. Gangliosides are not used as energy storage molecules. The hydrophobic tails on gangliosides form a conical shape rather than a cylindrical shape making close packing difficult. □ Gangliosides contain large headgroups making close packing difficult Gangliosides contain trans fatty acids resulting in a bent hydrophobic tail making close packing difficult Gangliosides contain several sugar molecules that can only localize to the cytosol preventing bilayer formation
