Iridodial is an
iridoid
Iridoids are a type of monoterpenoids in the general form of cyclopentanopyran, found in a wide variety of plants and some animals. They are biosynthetically derived from 8-oxogeranial. Iridoids are typically found in plants as glycosides, mos ...
. It is produced from
8-oxogeranial by the enzyme
iridoid synthase (IS). Iridodial is one of the substrates for the enzyme
iridoid oxidase (IO) which produces
7-deoxyloganetic acid.
Although it may not be known at this time whether the compound proper iridodial is actually present in natural plant species or not, the use of analogous ion iridodial cation is mentioned in several papers on iridoid biosyntheses in plant species.
