List 3 complex carbohydrates (1pt x 3)

1. Plant-derived digestible carbohydrate

2. Plant-derived indigestible carbohydrate

3. Animal-derived carbohydrat

1. Starch

2. Cellulose (vegetable fibers)

3. Glycogen

Explanation:

Carbohydrates: They are bio-organic molecules synthesized by plants. these molecules are mainly made up of carbon, hydrogen and oxygen and consists of 1 to many sugar unit.

Sugar unit: C₆H₁₂O₆

on the basis of their unit and structural complexity there are three types of carbohydrates

1. Sugars:

These carbohydrates are composed of 1 to 2 units of glucose and these sugars have simple in structure and digestible and easily absorbed in blood.

2. Oligosaccharides:

These carbohydrates are composed of 3 to 9 units of glucose and these are the simplest polysaccharides are simple in structure and easily can be hydrolysed and digestible upon hydrolyzation easily absorbed in blood.

3. Polysaccarides:

These carbohydrates are composed of more than 9 units of glucose and these are complex in structures. These polysaccharides are of long chain and high wight and some of these can be hydrolysed and digestible upon hydrolyzation, but some can not be broken into simple sugar by hydrolyzation and can not be digested.

Now we have to explain about Complex Carbohydrates

1. Plant-derived digestible carbohydrate:

Plant synthesize carbohydrates and they stored in the form of oligosaccharides and polysaccarides that are of long chain and complex structure. Among these complex carbohydrates starch are digestible.

2. Plant-derived indigestible carbohydrate

Plant synthesize carbohydrates and they stored in the form of oligosaccharides and polysaccarides that are of long chain and complex structure. Among these complex carbohydrates cellulose (vegetable fibers) are insoluble and can not be digestive.

3. Animal-derived carbohydrate

Animals store the simple sugar in the form of glycogen. These glycogen are long chains of glucose and can be re-used by the body in need of energy
