Carbohydrates – Monosaccharides, Disaccharides, Polysaccharides

February 24, 2020June 21, 2019 by Sagar Aryal

Carbohydrates definition Carbohydrates are molecules that contain carbon, hydrogen, and oxygen. There are twice as many hydrogen atoms as carbon or oxygen atoms. The general formula for a carbohydrate can be written as Cx(H2O)y. They act as the source of energy (e.g. glucose), as a store of energy (e.g. starch and glycogen) and as structural units (e.g. cellulose in plants …

February 24, 2020August 5, 2018 by Sagar Aryal

What are carbohydrates? The carbohydrates are a group of naturally occurring carbonyl compounds (aldehydes or ketones) that also contain several hydroxyl groups. It may also include their derivatives which produce such compounds on hydrolysis. They are the most abundant organic molecules in nature and also referred to as “saccharides”. The carbohydrates which are soluble in water and sweet in taste …
