	Gal	Galactose
	GalNAc	2-N-acetylgalactosamine
	Man	Mannose
	Fuc	Fucose

Glycan derivatization reactions	Permethylation	Conversion of all OH to O-methyl and NH to N- methyl³¹
Tandem MS terms	Backbone cleavage	Dissociation of a glycosidic bond
	Cross-ring cleavage	Dissociation across a monosaccharide ring
	Scar	A non-methylated site revealed by tandem MS dissociaton of a glycosidic bond in a permethylated glycan
