Common Name

Calendic acid

Description

Calendic acid is isolated from Calendula officinalis (pot marigold) seed oil Calendic acid (sometimes -Calendic acid) is an unsaturated fatty acid, named for the pot marigold (genus Calendula), from which it is obtained. It is chemically similar to the conjugated linoleic acids; laboratory work suggests it may have similar health benefits. Calendic acid is an omega-6 fatty acid. though not usually listed with this group. Calendic acid (8t,10t,12c-18:3) is synthesised in Calendula officinalis from linoleate (9c,12c-18:2) by an unusual 12-oleate desaturase (a FAD 2 variant) that converts the cis-double bond in position 9 to a trans,trans-conjugated double bond system (8t,10t). Calendic acid is an all-trans beta isomer has been described
