GlyTouCan G93860XO
glytoucan g93860xo
A polysaccharide that is α-<small>D</small>-Man<em>p</em>-(1→3)-[β-<small>D</small>-Man<em>p</em>-(1→6)]-β-<small>D</small>-Man<em>p</em>-(1→4)-β-<small>D</small>-Glc<em>p</em>NAc-(1→4)-β-<small>D</small>-Glc<em>p</em>NAc in which a hydroxy group in one of the terminal mannose moieties has been converted into the corresponding Neu5Ac-(1→?)-?-<small>D</small>-Gal-(1→?)-?-<small>D</small>-GlcNAc-(1→?)- glycoside, while two of the hydroxy groups on the other terminal mannose moiety have each been converted into the corresponding Neu<small><sub>5</sub></small>Ac-(1→?)-?-<small>D</small>-Gal-(1→?)-?-<small>D</small>-GlcNAc-(1→?)- glycoside.    For the structure shown, either one of the R1 atoms and two of the R2 atoms represent Neu5Ac-(1→?)-?-<small>D</small>-Gal-(1→?)-?-<small>D</small>-GlcNAc-(1→?)- groups or vice versa; the remaining R1 and R2 atoms are hydrogens.
