[Variation in the composition of fatty acids of zeaxanthin and astaxanthin monoesters in the ovary and hepatopancreas of Penaeus schmitti during ovogenesis].
The carotenoid esters of the shrimp, Penaeus schmitti, were investigated by thin layer chromatography and absorption spectrophotometry. Astaxanthin monoester and zeaxanthin monoester were identified in hepatopancreas and ovaries during the sexual development. The nature of fatty acids derived from these natural esters has been determined quantitatively by gas chromatography of their methyl esters. The variations of linkage between fatty acids and carotenoids during ovogenesis are measured. The role of zeaxanthin monoester in carotenoids transfer from hepatopancreas to ovaries during this sexual development, and relations between lipid and carotenoid metabolism are discussed.
