Zastosowanie

Neoxanthin has been used as a reference standard to determine the phenolic content and antioxidant activity of Phaeodactylum tricornutum extracts by high-performance liquid chromatography (HPLC).

Działania biochem./fizjol.

Neoxanthin is an allenic xanthophyll and one of the major carotenoids found in plants such as spinach and barley leaves. A trace amount of this pigment is also found in olive oil. Neoxanthin exists as two geometric isomers such as trans-neoxanthin and 9′-cis-neoxanthin. It acts as a precursor of abscisic acid. It plays a role in photoprotection by providing general antioxidant activity. Neoxanthin exhibits apoptotic and anti-proliferative effects.

MpBHY codes for a carotene β-ring 3(,3')-hydroxylase responsible for both zeaxanthin and lutein biosynthesis in liverwort. MpCYP97C functions as an ε-ring hydroxylase (zeinoxanthin 3'-hydroxylase) to produce lutein in liverwort. Xanthophylls are oxygenated or hydroxylated carotenes that are most abundant in
