<prompt> Which set of fatty acids is most effective increasing the cholesterol levels?Linoleic and linolenicMyristic and palmiticButyric and stearicOleic and palmitic  <response>: Lauric 12:0, myristic 14:0, and palmitic 16:0 acids raise cholesterol levels and are found primarily in animal fat and dairy products. Palmitic acid, the fatty acid that most effectively raises serum cholesterol levels, is also the major fatty acid found in palm and coconut oils. Stearic acid and fatty acids that have fewer than 10 carbon atoms tend not to raise cholesterol levels. Polyunsaturated fatty acids such as linoleic and linolenic and oleic acid an w-9 monounsaturated fatty acid found as approximately 70 of the total fatty acid in olive oil and 55 in canola oil tend to lower cholesterol levels.
