enzymes in digestion
Carbohydrate digestion is a crucial part of the digestive process. Enzymes play an essential role in breaking down the carbohydrates we eat into forms that can be absorbed by the body. Amylase, an enzyme found in saliva and pancreatic juice, initiates the digestion of starches into maltose, a disaccharide.
Once the carbohydrates reach the small intestine, enzymes like maltase, lactase, and sucrase further break down disaccharides into monosaccharides like glucose, fructose, and galactose.
These monosaccharides are then absorbed through the intestinal walls and into the bloodstream, providing energy to cells throughout the body. Without these enzymes, digestion of carbohydrates would not be efficient, leading to malabsorption and nutritional deficiencies.

hydrolysis reaction
The digestion of carbohydrates primarily involves a type of chemical reaction known as hydrolysis. Hydrolysis is a process in which a water molecule is used to break down a compound. In the context of carbohydrate digestion, hydrolysis occurs when water molecules are added to polysaccharides.
This reaction splits these complex carbohydrates into simpler sugar molecules. For instance, the polysaccharide starch is hydrolyzed to produce maltose, which is then further broken down to glucose through the addition of water.
Hydrolysis is an essential reaction in metabolism, enabling the body to convert large, indigestible molecules into smaller, absorbable ones. This reaction ensures that our bodies can efficiently extract energy from the food we consume.

polysaccharides and monosaccharides
Carbohydrates can be classified into two broad categories: polysaccharides and monosaccharides. Polysaccharides are complex carbohydrates made up of long chains of monosaccharide units. Examples include starch, glycogen, and cellulose. These polysaccharides need to be broken down during digestion to be of any use to the body.
Monosaccharides, on the other hand, are the simplest form of carbohydrates. They are single sugar molecules, such as glucose, fructose, and galactose. These are the end-products of carbohydrate digestion and are readily absorbed by the body.
During digestion, enzymes break down polysaccharides through hydrolysis into monosaccharides. For example, the enzyme amylase breaks down starch into maltose, which is then further hydrolyzed to yield glucose. These monosaccharides are vital as they serve as primary fuel sources for cellular processes.
