Explanation:
Carbohydrates are the organic compounds that contain a carbon, hydrogen and oxygen atoms which are chemically combined together.
Their general formula is [tex](CH_{2}O)_{x}[/tex] where x is any integer.
For example, lactose has chemical formula [tex]C_{12}H_{22}O_{11}[/tex] and it is a carbohydrate.
A carbohydrate can be monosaccharide, disaccharide, oligosaccharide or polysaccharide.
