where is a reducing end in this image?I initially thought it'd be on the middle oxygen connecting the lactose molecules since it's the only reducing sugar, but that was incorrect for some reason. 6CH OHНОННкоркОН НHзН ОННОНLactose (B form)B-D-galactopyranosyl-(1→4)-B-D-glucopyranoseGal( B1→4)Gic6CH OHHOCH,Н15ННВК н ноOH HНОCH₂OHНОНОН НSucroseB-D-fructofuranosyl a-D-glucopyranosideFru(2B+a1)Glc = Glc(a1+2B)Fru6CH_OHН15ННOHHOCH,OH HHOН32H ОНHОНTrehalosea-D-glucopyranosyl a-D-glucopyranosideGlc(a1 +1a)Glc6CH OHOH HOH H2OHН

1 2 Glycogenin is a homodimer of 37 kDa subunits. (Homodimer means identical subunits of type a that form a dimer of type a2). Glycogenin has a chain of a(1,4)-linked units of glucose attached to the sidechain of a tyrosine residue. The chain of a(1,4)-linked glucose units is a primer for the initiation of glycogen synthesis by glycogen synthase. Assume the dimer is stable and not in equilibrium with monomer subunits. Which of the answers below are plausible pathways for attaching or building the primer chain of glucose units? The branching enzyme attaches a chain of 7 glucose units to the tyrosine sidechain of glycogenin. 0 0 0 0 000 The transferase attaches 3 units of a(1,4)-linked glucose to the tyrosine sidechain of glycogenin. Glycogen synthase then extends the chain using UDP-Glc. 0 One glycogenin dimer builds the a(1,4)-llinked glucose chain on a subunit of another glycogenin dimer. -D-O Each subunit builds the a(1,4)-Ilinked glucose chain on the other subunit of the same dimer.…
