from the a(1,4) terminal chains of glycogen
brnaching enzyme removes a 7 residue grafment from chaisn of at least ___ residues
11 (needs 4 left over)
branching enzymes converts from the a(1,4) terminal chains of glycogen to a ___ chain of glycogen
a(1-6) glycogen chain
this introduces a branch, so now have 3 branches instead of 2
Glycogen polymers may contain up to___ Glu units each
Glycogen polymers contribute up to ___ of the rotal mass of 10% of th eottal mass of the liver
When Glu is needed, Phosphorylase breaks the glycosidic bond at the end of a Glycogen chain by addition of
a phosphate to give G1P
how long can glucose be removed from glycogen?
until terminal glucose on the chain is within 4 residues of a branch point where steric hinderance prevents further digestion by Phosphorylase
• Debranching enzyme transfers a ____ from the stub to the C4 hydroxyl at the end of another branch
two functions of debranching enzyme?
1. transfers a trisaccharide froms tub of c4 gtdroxyl at the end of another branch
2. also cleaves the reamin a,16 glu by hydrolysis
difference betw Phsophoglucomutase in conversion of G1P to G6P and Phosphoglycerate Mutase in conversion of 3PG to 2PG?
Ser-P intermediate instead of His-P in Phsophylycomutase
cost of temproailry storing glu in glycogen in muscle/liver
from g6p -> glycogen -> g6p
