29518447-6	2018	The acetylation modification mainly occurred at C-2, C-3 and C-6 positions of 1, 4-linked beta-D-galactose, and C-6 position of terminal-linked beta-D-galactose.	beta-D-galactose	90-106	complement C2	Homo sapiens	48-56	
24299779-3	2014	The sulfate groups are located principally on C-2 of beta-d-galactopyranose and 4,6-O-(1"-carboxyethylidene)-beta-d-galactopyranose residues and on C-6 of alpha-galactose residues.	beta-D-galactose	53-75	complement C2	Homo sapiens	46-49	
19621373-3	2009	Baseline separations of all enantiomers were achieved using both beta-D-glucose and beta-D-galactose derivates that have an equatorially oriented hydroxy group at C-2 position.	beta-D-galactose	84-100	complement C2	Homo sapiens	163-166	
11971864-5	2002	The substitution at the C-2 and C-3 position of beta-galactose in these oligosaccharides with alpha-fucose, alpha-GalNAc, alpha-Neu5Ac, or sulfate increased the binding ability for galectin-3, whereas the substitution at the C-4 or C-6 position diminished the affinity.	beta-D-galactose	48-62	complement C2	Homo sapiens	24-27
