Editing Sucrose (section)

===Synthesis and biosynthesis of sucrose===
The [[biosynthesis]] of sucrose proceeds via the precursors [[UDP-glucose]] and [[fructose 6-phosphate]], catalyzed by the enzyme [[Sucrose-phosphate synthase|sucrose-6-phosphate synthase]]. The energy for the reaction is gained by the cleavage of [[uridine diphosphate]] (UDP).
Sucrose is formed by plants, [[algae]] and [[cyanobacteria]] but not by other [[organism]]s. Sucrose is the end product of [[photosynthesis]] and is found naturally in many food plants along with the [[monosaccharide]] fructose. In many fruits, such as [[pineapple]] and [[apricot]], sucrose is the main sugar. In others, such as [[grapes]] and [[pear]]s, fructose is the main sugar.

====Chemical synthesis====
After numerous unsuccessful attempts by others, [[Raymond Lemieux]] and George Huber succeeded in synthesizing sucrose from [[acetylated]] glucose and fructose in 1953.<ref name = "Lemieux">{{cite journal|last1 = Lemieux|first1 = R.
