Fructose (/ ˈ f r ʌ k t oʊ s,-oʊ z /), or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose.It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed by the gut directly into the blood of the portal vein during digestion.
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Fructose can be converted into 2,5-dimethylfuran in a catalytic biomass-to-liquid process. The conversion of fructose to DMF proceeds via hydroxymethylfurfural. [3] [4] Fructose is obtainable from glucose, a building block in cellulose. [5] [6]
High-fructose corn syrup (HFCS), also known as glucose–fructose, isoglucose and glucose–fructose syrup, [1] [2] is a sweetener made from corn starch. As in the production of conventional corn syrup , the starch is broken down into glucose by enzymes.
Dense inverted sugar syrup (Trimoline) Inverted sugar syrup is a syrup mixture of the monosaccharides glucose and fructose, made by splitting disaccharide sucrose.This mixture's optical rotation is opposite to that of the original sugar, which is why it is called an invert sugar.
Fructose 1,6-bisphosphate, known in older publications as Harden-Young ester, is fructose sugar phosphorylated on carbons 1 and 6 (i.e., is a fructosephosphate). The β-D-form of this compound is common in cells. [1] Upon entering the cell, most glucose and fructose is converted to fructose 1,6-bisphosphate. [2] [3]
Hydroxymethylfurfural (HMF), also known as 5-(hydroxymethyl)furfural, is an organic compound formed by the dehydration of reducing sugars. [4] [5] It is a white low-melting solid (although commercial samples are often yellow) which is highly soluble in both water and organic solvents.
The synthesis of levulinic acid from hexoses (glucose, fructose) or starch in dilute hydrochloric acid or sulfuric acid. [4] [9] [10] [11] In addition to formic acid further, partly insoluble, by-products are produced. These are deeply colored and their complete removal is a challenge for most technologies.
