# What might the name "carbohydrate" might indicate about the chemical composition of sugars?

See the explanation.

#### Explanation:

The ratio of hydrogen to oxygen in carbohydrates is 2:1, the same as water. So it's as if the carbon atoms are combined with water. For monosaccharides the general formula is $\text{CH"_2"O}$.

Monosaccharides

$\text{C"_6"H"_12"O"_6}$ (glucose, fructose, galactose)

$\text{C"_5"H"_10"O"_5}$ (ribose)

Disaccharides

$\text{C"_12"H"_22"O"_11}$ (sucrose, maltose, lactose)

Polysaccharides

("C"_6"H"_10"O"_5")"_n" (starch and cellulose)

$\text{C"_24"H"_42"O"_21}$ (glycogen)
