Abstract

Using a thin layer chromatography the content and composition of krill lipids was examined in different sex and maturity stages. The content of lipids decreased in the following sequence: immature males — females with eggs — juvenile specimens — spent females — mature males. In females the differences concerned mainly phospholipids and waxes, in males — triacylglicerols; this fact proves the different utilisation of lipids for reproduction in both sexes.

Abstract

A composition of lipids of some Antarctic Crustacea (Euphausia superba. E. triacantha. Thysanoessa macrura and Mysidacea gen. sp. indet.) caught in the Admiralty Bay (South Shetlands) was compared. Lipids of E. superba differed in low content of waxes that evidences for different management of lipids than in other examined Crustacea.

Abstract

The photo-oxidability of lipids taken from 32 samples of krill from different dates of catch has been examined for photooxidation. Relations were indicated between the rate of accumulation of peroxides in the process of lipids, exposure and content of lipids in krill, its iodine value and amount number of carotenoids.

Abstract

The amount and composition of lipids m some Antarctic animals were studied. The material consisted of crustaceans (Euphausia superba, Paramoera sp., Orchomene sp.), tunicates (Salpa thompsoni) and vertebrates (Notothenia rossi marmorata and Hydrurga leptonyx). The author's data are discussed on the background of available literature information.

Abstract

Carotenoid composition of both penguin faeces and the lichen Caloplaca regalis has been analyzed by thin layer chromatography. Carotenoids in both samples are almost identical to those found in the krill, the main food of the penguins, including β-carotene, which is not found in other Theloschistaceae species.
