.png)
Biomolecules: Biomolecules are organic macromolecules which are produced by living organisms, essential for life. Carbon and hydrogen are basic units of biomolecules. They are classified into following categories: Carbohydrates Lipids proteins Carbohydrates: Chemically, carbohydrates are polyhydroxy aldehydes or ketones. The general formula is C n ( H 2 O ) n. The word carbohydrate means hydrated carbon. They are composed of carbon, hydrogen and oxygen as the same ratio in water. Classification of carbohydrates: Carbohydrates are classified into three groups. Monosaccharides Oligosaccharides polysaccharides Monosaccharides: These are simple and sweet sugar. These are easily soluble in water. Chemically, they are polyhydroxy aldehydes or ketones. With aldehyde group these sugar are called aldo-sugar and with ketone group is called keto-sugar . They are called trioses, tetroses, pentoses, hexoses and...
