Bioside is a member of the class of compounds known as steroidal saponins. Steroidal saponins are saponins in which the aglycone moiety is a steroid. The steroidal aglycone is usually a spirostane, furostane, spirosolane, solanidane, or curcubitacin derivative. Bioside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Bioside can be found in horseradish, which makes bioside a potential biomarker for the consumption of this food product. The joining of simple sugars into a double sugar happens by a condensation reaction, which involves the elimination of a water molecule from the functional groups only. Breaking apart a double sugar into its two simple sugars is accomplished by hydrolysis with the help of a type of enzyme called a disaccharidase. As building the larger sugar ejects a water molecule, breaking it down consumes a water molecule. These reactions are vital in metabolism. Each disaccharide is broken down with the help of a corresponding disaccharidase (sucrase, lactase, and maltase) .
