3α,4β,3α-Galactotetraose is a class of biochemical reagents used in glycobiology research. Glycobiology studies the structure, synthesis, biology, and evolution of sugars. It involves carbohydrate chemistry, enzymology of glycan formation and degradation, protein-glycan recognition, and the role of glycans in biological systems. This field is closely related to basic research, biomedicine, and biotechnology[1].

ChEBI: Alpha-D-Galp-(1->3)-beta-D-Galp-(1->4)-alpha-D-Galp-(1->3)-D-Galp is a galactotetraose comprised of four D-galactose residues connected sequentially by alpha(1->3), beta(1->4) and alpha(1->3) linkages.
