Monosaccharides may be defined as the carbohydrates that cannot be hydrolyzed into the simpler units. Disaccharides are the carbohydrate that can be hydrolyzed into two sugars.
The dehydration means the removal of water molecule and used in the synthesis of the disaccharides. Hydrolysis means the breakdown of disaccharides into simple monosaccharides sugar. The water molecule is used up in this reaction. The triglyceride formation involves the dehydration synthesis the glycerol and fatty acids are linked together. Three molecules of water are released in this reaction. The hydrolysis reaction occurs in the formation of triglycerides.
