Abstract. The changes of the phospholipid profile in residents living in Subpolar and Arctic regions were explored. Significantly lower levels of lysophosphatidylcholine, phosphatidylcholine, phosphatidic acid and high value of phosphatidylserine were revealed in women from Subpolar region compared to women from Arctic region, and increased levels of cardiolipin and low contents of phosphatidylcholine and monofosfoinozitida were revealed in men. In general, the content of phosphatidylcholine in northerners was 2-4 % of all phospholipids, what is significantly below the physiological standard (40-50 %).
Keywords: phospholipid profile, Subpolar and Arctic region, men, women.
