What is Citral?

Citral is different from other terpenoids in that it is actually a pair of isomers connected by a double bond; geranial (citral A) and neral (citral B). Often citral will be referred to as one of its two isomers–more commonly geranial–or as lemonal. Citral is found naturally in varying citrus such as lemon, orange, and lime. This terpenoid is also found in lemongrass and lemon balm. Citral is credited with giving specific citrus and grass their lemony scent.
