Question

Cellulose belongs to a group of molecules called

Answer 1

Answer:

Carbohydrates

Explanation:

Cellulose is the most abundant carbohydrate in nature.

Carbohydrate literally means hydrated carbons. Carbohydrates are found in all organisms. Carbohydrates are also called "saccharides" (which is derived from greek word "sackharon"meaning sugar)

Carbohydrates are composed of carbon, hydrogen and oxygen. Their general formula is Cx (H20)y

where x is a whole number ranging from three to many thousands

and y maybe same or different whole number.

For example, Glucose is a carbohydrate and its chemical formula is C6H12O6 ( x=6, y=6).

Chemically, carbohydrates are defined as polyhydroxy aldehydes or ketones or complex substances which upon hydrolysis yield polyhydroxy aldehyde or ketone subunits.

Carbohydrates are further divided as:

1. Monosaccharides
2. Oligosaccharides
3. Polysaccharides

MONOSACCHARIDES:

• They are simple sugars.
• Easily soluble in water
• Cannot by hydrolyzed into simpler subunits.

EXAMPLES: Glucose, fructose

DISACCHARIDES:

• They are composed of 2 monosaccharide sub-units liked together by glycosidic bonds.

EXAMPLES: Lactose

OLIGOSACCHARIDES:

• Less soluble in water
• They consist of small number (usually 3-10) of monosaccharide subunits.

EXAMPLES: raffinose

POLYSACCHARIDES:

• They are the most complex sugars.
• They are composed of large number of monosaccharide sub-units.
• They are usually branched
• They are usually tasteless.
• They are sparingly soluble or insoluble in water.

EXAMPLES: Cellulose, starch, glycogen (animal starch)
