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. [1] [2] Some commercially important fatty alcohols are lauryl, stearyl, and oleyl ...

Thus carbon α is C-2, carbon β is C-3, and so forth. Although fatty acids can be of diverse lengths, in this second convention the last carbon in the chain is always labelled as ω , which is the last letter in the Greek alphabet. A third numbering convention counts the carbons from that end, using the labels "ω", "ω−1", "ω−2".
The carbon chains in plant alkanes are usually odd-numbered, between 27 and 33 carbon atoms in length, [40] and are made by the plants by decarboxylation of even-numbered fatty acids. The exact composition of the layer of wax is not only species-dependent but also changes with the season and such environmental factors as lighting conditions ...
The carbons of the chain are conventionally numbered from 1 to n, starting from the end which is closest to the carbonyl. If the carbonyl is at the very beginning of the chain (carbon 1), the monosaccharide is said to be an aldose, otherwise it is a ketose. These names can be combined with the chain length prefix, as in aldohexose or ...
Crotonic acid has 4 carbons, is included in croton oil, and is a trans-2-mono-unsaturated fatty acid.C 3 H 5 CO 2 H, IUPAC organization name (E)-but-2-enoic acid, trans-but-2-enoic acid, numerical representation 4:1, n-1, molecular weight 86.09, melting point 72–74 °C, boiling point 180–181 °C, specific gravity 1.027.
CPs are subdivided according to their carbon chain length into short-chain CPs (SCCPs, C 10–13), medium-chain CPs (MCCPs, C 14–17) and long-chain CPs (LCCPs, C >17). Depending on chain length and chlorine content, CPs are colorless or yellowish liquids or solids. [1]
