Carbohydrates as molecules range from the simplest possessing the formula C-HOHx, such as glucose C6H12O6, and exemplified by glucose,  to the more complex disaccharides sucrose and galactose, to large polysaccharides such as cellulose, hyaluronic acids and structurally complex molecules such as chitin. Monosaccharides, those compounds possessing one sugar, are exemplified by glucose, fructose and galactose, while disaccharides such as sucrose, known as table sugar, and lactose are part of everyday diets. 

Our carbohydrates are of the highest quality and are in Technical, ACS Reagent, USP, NF and Food Grades. Ask A Chemist - we can help you find what you need and supply the compounds you're looking for.
