What molecules are we?

Lauric acid [1] and myristic acid [2] are saturated fatty acids. Their formal names are dodecanoic acid and tetradecanoic acid, respectively. Both are white solids that are very slightly soluble in water.
Lauric acid esters (principally triglycerides) are found only in vegetable fats, primarily from coconut milk and oil, laurel oil, and palm kernel oil. In contrast, myristic acid triglycerides occur in plants and animals, notably in nutmeg butter, coconut oil, and mammalian milk.
Fatty acids have a bad name because they are strongly associated with high serum cholesterol levels in humans. Lauric and myristic acids are among the worst offenders; therefore, many governmental and health organizations advise that coconut oil and milk, among other high鈥搒aturated fat substances, should be excluded from the diet.
There is, however, a bright side for these acids. May 8 is听, perhaps the one day of the year you may wish to throw caution to the wind and eat your fill of lauric and myristic acids.
