SUBSTANCE? COMPOSITION Glucose Starch Saturated Fats Fats Keratin Hemoglobin Deoxyribose DNA RNA

Answer 1

1.Glucose-

*C6H12O6

*Energy is required for normal functioning of body.Brain, neurons and developing red blood cells can use only glucose for energy.

2.Sucrose-

*It is made of 50% glucose and 50% fructose.   

*Sucrose provides your body with the energy required to perform physical amd mental functions.

3.Starch-

*(C6H10O5)n

*Starch is the main way plant cells store energy in the form of glucose.

4.Glycogen-

*C24H42O21

*It functions as secondary long term energy storage with primary energy stores being fats held in adipose tissue.

5.Cellulose-

*(C6H10O5)n

*It is major component of tough cell walls that surround plant cells and makes plant stems, leaves, branches so strong.

6.Saturated fats-

*It is made of long chain of carbon atoms.

*It is found in meat, dairy products, butter and coconut oil.It plays key role in immune health.

7.Unsaturated fats-

*It is monounsaturated if it has one double bond and it is polyunsaturated if it has more than one double bond.

*It is found in plant foods and vegetable oils.Eating moderate amounts can benefit your health.

8.Keratin-

*It is a family of fibrous structural protein.

*It protects epithelial cells from damage or stress.

9.Hemoglobin-

*It is a quaternary structure comes from its four subunits in roughly a tetrahedral arrangement.

*It carries oxygen from respiratory organs to rest of the body.

10.Deoxyribose-

*C5H10O4

*It is the main building block of DNA and is found in every nucleotide

that makes up long chain of genetic information.

11.DNA-

*It is made up of molecules called nucleotides.Each nucleotide contains a phosphate group, sugar group and nitrogen base.

*It is found in mitochondria and chloroplast and it carries genetic instructions used in growth ,development, functioning and reproduction.

12.RNA-

*Each nucleotide in RNA contains ribose sugar with carbon numbered 1' through 5'.It lacks thyamine and has uracil instead of it.

*It stores and transmits genetic information that is vital for the manufacture of protein.It is found in cytoplasm.
