The name "fructose" was coined in 1857 by William Miller, an English chemist.
Also known as fruit sugar, it is a monosaccharide (C6H12O6). Note that the molecular formula of fructose is the same as glucose, but they are differentiated by the characteristic group, which in the fructose molecule is a ketone group, while in the glucose molecule is an aldehyde.
For this reason, due to the presence of a ketone group in its structure, fructose can be classified as a ketosis.
Fructose can be found in honey and many fruits. It is also called levulose.
It can also be obtained by hydrolysis of a polysaccharide, inulin.
Pure, dehydrated fructose is very sweet, colorless, odorless, solid and crystalline. It is the most water soluble sugar of all.
