Lactose, All you need to know ! !😵

Facts known to us           :

• Lactose is a disaccharide that yields D-glucose and D-galactose on hydrolysis.
• Lactose is one-sixth times sweeter than sucrose

Facts we need to know   :

It is designated as 4-ortho-β-D-galactopyranosyl-D-glucopyranose.

 α-lactose: Ordinary commercial lactose is α-lactose monohydrate.

•  It is prepared by concentrating an aqueouslactose solution to super saturation and allow for crystallization to take place at a modern rate below 93.5 0C. 

 β-lactose: This is the other isomeric form lactose. 

• It exhibits a specific rotation of +35.00on anhydrous weight basis. Above 93.50C crystallization or drying of lactose solutions yields β anhydrate.
