Palmitic acid (hexadecanoic acid in IUPAC nomenclature) is a fatty acid with a 16-carbon chain. It is the most common saturated fatty acid found in animals, plants and microorganisms. [ 9 ] [ 10 ] Its chemical formula is CH 3 (CH 2 ) 14 COOH , and its C:D ratio (the total number of carbon atoms to the number of carbon-carbon double bonds) is 16:0.
Palm oil has an especially high concentration of saturated fat, specifically the 16-carbon saturated fatty acid, palmitic acid, to which it gives its name. Monounsaturated oleic acid is also a major constituent of palm oil. Unrefined palm oil is a significant source of tocotrienol, part of the vitamin E family. [140] [141]
Palmitoleic acid is found in trace amounts in most foods except for sardine oil, which contains 15% of this acid as a component of triglycerides. [1]Other dietary sources of palmitoleic acid include breast milk, [3] a variety of animal fats, vegetable oils, and marine oils.

A 2022 review of cohort studies found that the risk of type 2 diabetes was not associated with dietary intake of total saturated fats, palmitic acid, and stearic acid. Dietary lauric acid and myristic acid , present in plant oils and also in dairy fat, were associated with reduced risk of diabetes.
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
Dairy products are one of the primary sources of dietary omega−7 fatty acids. However, the production of omega−7 fatty acids in cows is heavily diet-dependent. [7] Specifically, a reduction in the proportion of herbage consumed by a cow is correlated with a significant decrease in the omega−7 fatty acid content of the cow's milk. Rumenic ...
Palm kernel oil, palm oil, and coconut oil are three of the few highly saturated vegetable fats; these oils give the name to the 16-carbon saturated fatty acid palmitic acid that they contain. Palm kernel oil, which is semi-solid at room temperature , is more saturated than palm oil and comparable to coconut oil.
