Correct Answer - Option 2 : Carbohydrate
The correct answer is Carbohydrate.
-
Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms.
- Carbohydrates are naturally occurring sugars, starches and fibre in food. All carbohydrates are made up of sugar molecules. Sugar molecules linked together form starches and fibre. In the body, starches and sugars are broken down in the digestive system to glucose.
- Proteins usually are almost neutral molecules; that is, they have neither acidic nor basic properties. This means that the acidic carboxyl (―COO−) groups of aspartic and glutamic acid are about equal in number to the amino acids with basic side chains.
- During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood. Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.
So, Carbohydrate bio-molecule does not contain acid.
