The brush border bound hydrolase linked with sucrase is

Hydrolysis of sucrose (optical rotation +66.5deg) will produce one molecule of glucose (+52.5deg) and one molecule of fructose (-92deg). Therefore the products will change the dextrorotation to levorotation, or the plane of rotation is inveed. Equimolecular mixture of glucose and fructose thus formed is called inve sugar. The enzyme producing hydrolysis of sucrose is called sucrase or invease. Honey contains inve sugar. Inve sugar is sweeter than sucrose.Ref: DM Vasudevan, page no: 68
