Question

Explain, in terms of dehydration synthesis and hydrolysis reactions, how disaccharides and monosaccharides can be interconverted and how triglycerides can be formed and broken down.

Answer 1

Answer:

Disaccharides are formed from monosaccharides by dehydration synthesis. A water molecule is formed when two monosaccharides are covalently bonded together. Monosaccharides are formed from disaccharides by hydrolysis. A water molecule is used to form two monosaccharides from a disaccharide.

Explanation:

When triglycerides are formed dehydration synthesis occurs because the covalent bonds between the glycerol and fatty acids releases 3 water molecules. When triglycerides are broken down hydrolysis occurs because 3 water molecules are used to form glycerol and 3 fatty acids.

Answer 2

Answer:

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.
