The cell wall is an important structural feature found in plant cells, bacteria, and fungi. It is made primarily of cellulose (a polysaccharide) in plants, which provides rigidity and strength, helping the cell maintain its shape and resist external pressure.

Deoxyribose is the sugar component of DNA, providing structural support to the DNA molecule. It is a five-carbon sugar that forms the backbone of the DNA strand, linking together with phosphate groups to form the DNA structure.

DNA (Deoxyribonucleic Acid) is the molecule that carries genetic information in all living organisms. It is composed of nucleotides, which include the sugar deoxyribose. The structure of DNA enables it to store and transmit genetic instructions.

Amylose is a form of starch, a polysaccharide found in plants. It serves as the primary form of energy storage in plants, especially in tubers and seeds. Amylose is made up of long chains of glucose molecules and can be broken down into glucose when the plant needs energy.

Dextran is a polysaccharide found in some bacteria and yeast. It also serves as a storage form of energy, much like glycogen, but it is found in microorganisms.

Glycogen is a polysaccharide that acts as a form of energy storage in animals, especially in the liver and muscles. It is made up of many glucose units and can be broken down into glucose when the body needs energy.

Lactose is another disaccharide found in milk, made of glucose and galactose. After digestion, lactose is broken down into glucose, which provides energy, especially in infants and young mammals.

Sucrose, a disaccharide made of glucose and fructose, is a common sugar found in many foods like fruits and table sugar. When consumed, it is broken down into glucose, providing an energy source for the body.

Glucose is a monosaccharide (simple sugar) that serves as one of the primary energy sources for our cells. It is absorbed into the bloodstream and used quickly for energy.
