2Polysaccharides Flashcards
Amylopectin and glycogen(sugar in liver) are polymers of:
Polymers of glucose
They have branch points that are the (alpha 1➡️6) branch points where a sugar will have another linkage to glucose (alpha 1➡️4) and second one via (alpha 1➡️6). By branching we can compact glucose into a much smaller space.
Glc(alpha 1➡️4)x repeating
Amylose is formed of many of these glucose bonds.
Simple form of starch.
Alpha 1➡️4 bonds are easily broken by enzyme amylase.
A variation of amylose is cellulose
It is a string of glucoses and is linked by (Beta 1➡️4). Humans do not possess the enzymes to break down this kind of link….like plant fiber.
Starch and glycogen are both polymers of:
Alpha-D- glucose
From the abbreviated name of the compound Gal(beta1➡️4) Glc we know that:
C-4 of glucose is joining to C-1 of galactose by glycosidic bond
When the linear form of glucose cyclizes, the product is an:
Hemiacetal
