The oil contains predominantly medium chain triglycerides, with roughly 92% saturated fatty acids, 6% monounsaturated fatty acids, and 2% polyunsaturated fatty acids. Of the saturated fatty acids, coconut oil is primarily 44.6% lauric acid, 16.8% myristic acid a 8.2% palmitic acid and 8% caprylic acid, although it contains seven different saturated fatty acids in total. Its only monounsaturated fatty acid is oleic acid while its only polyunsaturated fatty acid is linoleic acid. Unrefined coconut oil melts at 24-25°C (76°F) and smokes at 170°C (350°F),while refined coconut oil has a higher smoke point of 232°C (450°F). Among the most stable of all oils, coconut oil is slow to oxidize and thus resistant to rancidity, lasting up to two years due to its high saturated fat content.[citation needed] In order to extend shelf life, it is best stored in solid form (i.e. below 24.5°C [76°F]).
