From Simple English Wikipedia, the free encyclopedia
The color of anegg yolk is from xanthophyll pigments.
Xanthophylls are types ofyellowpigments that can be seen in natural objects. They are found in theleaves of most greenplants. They are difficult to see in a healthy leaf, becausechlorophyll pigments make the leaf green. Unlike chlorophyll, however, xanthophylls do not needlight for production. Therefore, leaves will only show the yellow pigments if the leaf does not get enough light (etiolation).[1]
The name comes from the Greek words for "yellow" (xanthos,ξανθός),[2] and "leaf" (phyllon,φύλλον).[3]
