Structure of Xanthophyll (CAS NO.127-40-2):
IUPAC Name: (1R,4R)-4-[(1E,3E,5E,7E,9E,11E,13E,15E,17E)-18-[(4R)-4-Hydroxy-2,6,6-trimethylcyclohexen-1-yl]-3,7,12,16-tetramethyloctadeca-1,3,5,7,9,11,13,15,17-nonaenyl]-3,5,5-trimethylcyclohex-2-en-1-ol
Product Category of Xanthophyll (CAS NO.127-40-2): Carotenoids;Natural Plant Extract
Lutein (CAS NO.127-40-2) is one of over 600 known naturally occurring carotenoids. Found in green leafy vegetables such as spinach and kale, it is employed by organisms as an antioxidant and for blue light absorption.
Xanthophyll (CAS NO.127-40-2) has primarily been used as a natural colorant due to its orange-red color. And it was traditionally used in chicken feed to provide the yellow color of broiler chicken skin.
