^a)In the shorthand nomenclature for fatty acids and bases, the number before the colon refers to the carbon chain length and the number after the colon gives the total number of double bonds in the molecule. For long chain bases, d denotes dihydroxy and t denotes trihydroxy. Thus, d18:1 designates sphingosine (1,3-dihydroxy-2-aminooctadecene) and t18:0 phytosphingosine (1,3,4-trihydroxy-2-aminooctadecane). Fatty acids with a 2-hydroxy group are denoted by the prefix h before the abbreviation e.g. h16:0.
