alpha-D-Galp-(1->4)-beta-D-Galp-(1->4)-beta-D-Glcp-yl group
alpha-d-galp-(1->4)-beta-d-galp-(1->4)-beta-d-glcp-yl group
A trisaccharide β-<small>D</small>-glucosyl group obtained by removal of the hydroxy group from the hemiacetal function of α-<small>D</small>-galactosyl-(1→4)-β-<small>D</small>-galactosyl-(1→4)-β-<small>D</small>-glucose. Part of, and the proposed epitope from, α-<small>D</small>-galactosyl-(1→4)-β-<small>D</small>-galactosyl-(1→4)-β-<small>D</small>-glucosyl-(1↔1)-ceramide (globoside G<small><sub>b3</sub></small>Cer; globotriosylceramide; CTH).
