• Description: α-Linolenic acid ethyl ester is an esterified form of α-linolenic acid (Item Nos. 90210 | 21910). It increases cyclin E levels and the activity of Cdk2/cyclin E, ERK, and JNK in hepatic stellate cells when used at a concentration of 50 μM. α-Linolenic acid ethyl ester (25 μg/ml) inhibits the growth of S. mutans, C. albicans, and P. gingivalis by 98, 72, and 92%, respectively, in vitro. It has been found in biodiesel produced from castor oil using ethanol. α-Linolenic acid ethyl ester has been used as a substrate in lipid peroxidation assays for antioxidant activity.
• Uses: An exogenous source of α-linolenic acid. ethyl linolenate is an emollient reportedly used in indoor tanning preparations. It is not very popular as it may pose rancidity problems. It may also be used as an ingredient to enhance the fragrance of a product. Linolenic Acid Ethyl Ester is the ethyl ester derivative of Linolenic Acid (L467650); an essential fatty acid that occurs mostly as the glyceride in most drying oils. Also a nutrient.
