Even though sucrose biosynthesis is an integral part of starch metabolism, sucrose often
is not the predominant sugar that accumulates in fruits. Sucrose is further converted into
glucose and fructose by the action of invertase, which is characteristic to many ripe fruits.
Or, by the actions of sucrose synthase and UDP-glucose pyrophosphorylase, glucose-1-
phosphate can be regenerated from sucrose. As well, sugar alcohols such as sorbitol and
mannitol are major transport and storage components in apple and olive, respectively.
