The formation of pyranose and furanose forms of sugar generates a new asymmetric carbon, giving rise to α- and β‑forms. If the resulting anomeric alcohol group is above the plane of the sugar, the structure is known as

a. the D‑enantiomer.
b. the epimeric stereoisomer.
c. the β‑anomer.
d. the α‑anomer.
e. the L‑enantiomer.

Explain how the integumentary system plays a crucial role in the ability to maintain homeoestasis

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
