Simple carbohydrate. Sucrose is hydrolyzed to glucose and fructose by dilute acids and by invertase, a yeast enzyme. Upon hydrolysis the optical rotation falls and is negative when the hydrolysis is complete. The mixture of glucose and fructose is known as "Invert sugar".
Sucrose can be used to prepare density gradients for cell organelle separation. Sucrose is a main component of culture media. It can also be used in various enzymatic assays.
Soluble in water (1 g/0.5 ml at 25°C; 1 g/0.2 ml boiling water), ethanol (1 g/170 ml) or methanol (1 g/100 ml); moderately soluble in glycerol or pyridine.
