The attachment position of the sulfate groups to the glucuronic acid units and amino sugars is still undetermined. It is possible that these compounds are involved in maintaining the integrity ... WebbFormula and Molecular Weights. The formula weight of a substance is the sum of the atomic weights of each atom in its chemical formula. For example, water (H 2 O) has a formula weight of: 2 × (1.0079 amu) + 1 × (15.9994 amu) = 18.01528 amu. If a substance exists as discrete molecules (as with atoms that are chemically bonded together) then ...
