An example of a fatty alcohol. Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils. The precise chain length varies with the source.
As a derivative of methanol, triphenylmethanol is expected to have a pK a in the range of 16-19. Typical of alcohols, resonance offers no stabilization of the conjugate base due to being bonded to a saturated carbon atom. Stabilization of the anion by solvation forces is largely ineffective due to the steric influence of the three phenyl groups.

1-Tetradecanol, or commonly myristyl alcohol (from Myristica fragrans – the nutmeg plant), is a straight-chain saturated fatty alcohol, with the molecular formula CH 3 (CH 2) 12 CH 2 OH. It is a white waxy solid that is practically insoluble in water, soluble in diethyl ether , and slightly soluble in ethanol .
Generally, the epidermal lipid matrix is composed of an equimolar mixture of ceramides (about 50% by weight), cholesterol (25%), and free fatty acids (15%). [39] Saturated fatty acids 16 and 18 carbons in length are the dominant types in the epidermis, [39] [40] while unsaturated fatty acids and saturated fatty acids of various other lengths ...
Melting point: 75 °C (167 °F; ... (lignoceryl alcohol) is a fatty alcohol containing 24 carbon atoms, usually derived from the fatty acid lignoceric acid.
The fatty acids from each source are chemically identical. [7] The Vegan Society, which discourages eating animal-based foods, flags E471 as potentially animal based. [8] The World Health Organization’s (WHO) report on the toxicological evaluation of mono- and diglycerides states that, “Food fats are in the main triglycerides. However, many ...
Tridecylic acid, or tridecanoic acid, is the organic compound with the formula CH 3 (CH 2) 11 CO 2 H. It is a 13-carbon saturated fatty acid. It is a white solid. A laboratory preparation involves permanganate oxidation of 1-tetradecene (CH 3 (CH 2) 12 CH=CH 2). [8]
