Abstract
The composition and content of fatty acids of the sand lizard (Lacerta agilis) and its potential food objects in the shore and steppe biotopes were studied. For the first time, it was established that the content of long-chain omega-3 polyunsaturated fatty acids, primarily eicosapentaenoic acid (EPA), significantly increases in the tissues of lizards from a shore biotope during the period of emergence of amphibious insects from the nearby saline Lake Shira. Among all the food sources of lizards, the highest EPA content was found in chironomid imago. The content of docosahexaenoic acid (DHA) in the muscles of the lizards was also high, although this acid was not detected in the invertebrates that the lizards consumed. In this regard, it was assumed that the sand lizard is able to biosynthesize DHA from biochemical precursors contained in food.
期刊介绍：
Doklady Biochemistry and Biophysics is a journal consisting of English translations of articles published in Russian in biochemistry and biophysics sections of the Russian-language journal Doklady Akademii Nauk. The journal''s goal is to publish the most significant new research in biochemistry and biophysics carried out in Russia today or in collaboration with Russian authors. The journal accepts only articles in the Russian language that are submitted or recommended by acting Russian or foreign members of the Russian Academy of Sciences. The journal does not accept direct submissions in English.
