A
Mirror images
6
Q
Pyranose
A
a 6 carbon cyclic sugar yields to alpha and beta
7

Anomer
A
refer to alpha and beta formations
Alpha - Down
Beta - Up
9
Q
anomeric carbon
A
Carbon when cyclization occurred
10
Q
non reducing end
A
Side of the ring where it is unable to be reduced further because a reduction already occurred.
