Fatty Acids and Sterols in Avena Sativa L. in Yakutia Permafrost
Abstract The authors of this study examined the seasonal changes in qualitative and quantitative contents of fatty acids, total lipids, phospholipids, and sterols of the common oat ( Avena sativa L. ) that were sown at different times. They grow in Yakutia permafrost and undergo inter-season cold ha...
