摘要

Carotenoids are fat-soluble pigments synthesised by photosynthetic organisms (Brush, 1990). Conversely, animals are incapable of synthesizing carotenoids de novo, and they must obtain them through their diet. However, some animal species are able to make some alterations to the basic chemical structure, converting ingested carotenoids into more oxidized and differently coloured forms (Schiedt, 1998).
