In this problem, we're given three different saccharides, a, b, and c.
00:05
We want to know which one of these, if any, is digestible by humans.
00:10
Now, we as humans only have the appropriate enzymes to be able to digest monomers linked by alpha -14 glycosidic linkage.
00:20
We, however, do not possess the appropriate enzymes to be able to digest and break down beta linkage.
00:25
So this problem is really asking us which one of these saccharides exhibits only 1 -4.
00:31
Or alpha glycosidic linkage.
00:34
We therefore know that if any of these saccharides exhibit beta linkage that humans cannot digest it.
00:41
So what distinguishes alpha and beta isomers from one another in this scenario is the relative position of this hydroxy group and when bonded to this monomer, this oxygen, off of this one carbon...
