So we want to identify for the disaccharides in a and b.
00:09
C, of course, is a trisaccharide, so it wouldn't apply in this question.
00:14
Whether they're digestible, and if not, in what form would they be digestible? so just look at b and c, first of all.
00:23
Notice that the linkage from the ring on the left, that bond to the oxygen points downward.
00:33
And those bonds are hydrolyzable.
00:36
Now, in c, the linkage between the second and third rings, that oxygen points up relative to the second ring.
00:47
And so that's a beta linkage, and that is not hydrolyzable...
