Sucrose is a disaccharide formed from condensation of glucose and fructose to produce α-D-glucopyranosyl-(1→2)-β-D-fructofuranoside. Sucrose has 8 hydroxyl groups which can be reacted with fatty acid esters to produce sucrose esters.
Fatty acid esters (FAEs) are a type of ester that result from the combination of a fatty acid with an alcohol. When the alcohol component is glycerol, the fatty acid esters produced can be monoglycerides, diglycerides, or triglycerides. Dietary fats are chemically triglycerides.
An example of an ester formation is the substitution reaction between a carboxylic acid (R−C(=O)−OH) and an alcohol (R'OH), forming an ester (R−C(=O)−O−R'), where R and R′ are organyl groups, or H in the case of esters of formic acid. Glycerides, which are fatty acid esters of glycerol, are important esters in biology, being one of ...

Triglycerides, the energy-yielding dietary fats, consist of three fatty acids bonded in the form of esters to a glycerol backbone. Olestra uses sucrose as the backbone in place of glycerol, and it can form esters with up to eight fatty acids. [17] Olestra is a mixture of hexa-, hepta-, and octa-esters of sucrose with various long chain fatty acids.
Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae [2] but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters. In any of these forms, fatty acids are both important dietary ...
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

Sucrose octaacetate is a chemical compound with formula C 28 H 38 O 19 or (C 2 H 3 O 2) 8 (C 12 H 14 O 3), an eight-fold ester of sucrose and acetic acid. Its molecule can be described as that of sucrose C 12 H 22 O 11 with its eight hydroxyl groups HO – replaced by acetate groups H 3 C–CO 2 –. It is a crystalline solid, colorless and ...
