fructose

/ˈfrʌkˌtoʊs/

Fructose is a kind of sugar. You consume fructose every time you eat an apple or a bunch of grapes, or when you stir honey into your tea and take a sip.

Fructose is also known as "fruit sugar" because it's present in most types of fruit. Chemically, fructose is a simple or hexose sugar, one with six carbon atoms in it, and it's absorbed directly into your bloodstream when you eat it. It's also one of the very sweetest sugars. The word dates from 1857, from the Latin fructus, or "fruit," and the suffix -ose, used in chemical names of sugars.
