3.2.1 Structure of Carbohydrates
The name carbohydrate owes its origin to the fact that most substances of this class have empirical formulas suggesting they are carbon ”hydrates” in which the ratio of carbon to hydrogen to oxygen atoms is 1:2:1.
For example, the empirical formula is of D-glucose is C6H12O6. This also can be written as (CH2O)6 or C6(H2O)6. Many carbohydrates conform to the empirical formula (CH2O)n while others do not show this ratio. |
