These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm trees (species Elaeis guineensis ), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate.
Ascorbyl palmitate is an ester formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C. In addition to its use as a source of vitamin C , it is also used as an antioxidant food additive ( E number E304).
The apexes of the anion plot are sulfate, chloride and carbonate plus hydrogen carbonate anions. The two ternary plots are then projected onto a diamond. [ 3 ] The diamond is a matrix transformation of a graph of the anions ( sulfate + chloride / total anions) and cations ( sodium + potassium /total cations).
Retinyl palmitate, or vitamin A palmitate, is the ester of retinol and palmitic acid, with formula C 36 H 60 O 2. It is the most abundant form of vitamin A storage in animals. [2] An alternate spelling, retinol palmitate, which violates the -yl organic chemical naming convention for esters, is also frequently seen. [citation needed]

[citation needed] Polar solvents, such as acetonitrile, THF, and water, tend to bind to electrophilic centers, in which cases, the use of a non-coordinating anion is pointless. Salts of the anion B[3,5-(CF 3) 2 C 6 H 3] − 4 were first reported by Kobayashi and co-workers. For that reason, it is sometimes referred to as Kobayashi's anion. [7]

Anesthetics compete with palmitate in ordered lipids and this release gives rise to a component of membrane-mediated anesthesia. For example the anesthesia channel TREK-1 is activated by anesthetic displacement from GM1 lipids. [16] The palmitoylation site is specific for palmitate over prenylation.
