Answer 1

Answer:

Monosaccharide: single sugar molecule, glucose

Disaccharide: formed from two monosaccharide units, table sugar Polysaccharide: three or more sugar molecules, starch

Explanation:

Monosaccharides are simple carbohydrates as they do not undergo hydrolysis and contain a single sugar molecule (C₆H₁₂O₆). Monosaccharides are important sources of energy for the functioning of the human body.

The main monosaccharides are: Glucose (found in fruits and honey), galactose (found in milk), fructose (also found in honey and fruits) and ribose (composes the structure of DNA - ribonucleic acid).

Disaccharides have two monosaccharide units and are the most important oligosaccharides (formed by the union of 2 to 10 monosaccharides). Disaccharides are water soluble and are part of our daily diet, such as table sugar.

The main disaccharides are: Sucrose (composed of glucose + fructose), Lactose (composed of glucose + lactose) and Maltose (composed of glucose + glucose)

Polysaccharides, in turn, are composed of a large number of monosaccharide molecules (some have more than 10), with glucose being the monosaccharide most present in the formation of polysaccharides.

The best known polysaccharides are: Starch (present in various plant species, used as an energy source for our body), glycogen (acts as an energy reserve, being synthesized in humans in the liver and muscles) and cellulose (present mainly in the cell wall of vegetables, it is not digested by the human organism but is of great importance for bowel function).

Answer 2

Answer:

Carbohydrates are also called as saccharides and they are classified as Monosaccharides, oligosaccharides and polysaccharides.

Explanation:

Mono-saccharides - Carry only single sugar molecule. Example: Glucose, fructose and ribose.

Oligo-saccharides - contain 2-10 sugar molecules. If a saccharide is made up of 2 sugar molecules then its called disaccharide. If it contains 3 sugar molecules then its called trisaccharide. Example of disaccharides: Sucrose which is the table sugar is made of glucose + fructose. Lactose is the milk sugar which is made up of galactose and glucose.

Polysaccharides - these contain more than 10 sugar units. Example: starch, glycogen, cellulose.
