The three most common disaccharides (sucrose, maltose, and lactose) all contain at least one glucose monomer (sucrose=glucose+fructose, maltose=glucose+glucose, lactose=glucose+galactose), and the vast majority of other disaccharides also contain at least one glucose. the only outliers to this that I have found are xylobiose (xylose+xylose), rutinulose (rhamnose+fructose), melibulose (galactose+fructose), lactulose (galactose+fructose), and mannobiose (mannose+mannose), and these all seem to be relatively niche/uncommon. glucose is also one of the only monosaccharides I can find that binds with itself to form a disaccharide, and I have not found any examples of a fructose+fructose or galactose+galactose disaccharide. What property of glucose makes it so that glucose found in (and is so integral to) so many disaccharides instead of a different monosaccharide, such as fructose or galactose, and why is it able to commonly form a bond with itself, unlike fructose or galactose?  (link to wikipedia article containing list of disaccharides with the monosaccharides they are composed of: https://en.wikipedia.org/wiki/Disaccharide)
