What else can I help you with?
Why does carotenes move more rapidly with the solvent then the xanthophylls?
Carotenes are less polar than xanthophylls, so they have a greater affinity for the nonpolar solvent used in chromatography. This difference in polarity causes the carotenes to move more rapidly through the chromatography column compared to xanthophylls.
Is zeaxanthin the same as violaxanthin?
In a way no because, xanthophylls contain oxygen atoms, while carotenes are purely hydrocarbons with no oxygen. Xanthophylls contain their oxygen either as hydroxyl groups and/or as pairs of hydrogen atoms that are substituted by oxygen atoms acting as a bridge
