How many stereoisomers of citral are possible?
Abstract. Purpose: Citral is composed of a random mixture of two geometric stereoisomers geranial (trans-citral) and neral (cis-citral) yet few studies have directly compared their in vivo antitumor properties.
What is the difference between Geranial and neral?
Geranial and neral both have a lemon scent, however, neral has a milder, and sweeter lemon odor. These compounds are used individually or together depending upon the desired scent or flavor since they are used in perfumes, candy and even soft drinks.
What is the relationship between Geranial and neral?

Is Geranial and neral more stable?
The trans form, geranial, has greater conjugation and more stable conformation, whereas the cis isomer, neral, has a less effective conjugation structure, and when reacting with other substances there is greater steric hindrance.
Does citral contain vitamin C?
It contains sulfur compounds (allicin, alliin, allyl sulfides), terpenes (linalool, α-phellandrene, citral, geraniol), and high levels of phosphorous, calcium, iron, selenium, germanium, vitamins like riboflavin, thiamine, nicotinic acid, and vitamin C.
