Abstract
Naturally occurring n-tridecanoic acid was first isolated from coconut oil (Jantzen & Witgert, 1939; Nobori, 1942), while the branched-chain C,, acid ((+ )-10-methyldodecanoic acid) was first found in -degras (Weitkamp, 1945) and later in mutton fat (Hansen, Shorland & Cooke, 1954 b). In the present paper the occurrence in animal fats of n-tridecanoic and 1 1-methyldodecanoic acids is established for the first time. (+)-10-Methyldodecanoic acid has also been isolated. In Part 6 of this series Shorland, Gerson & Hansen (1955) reported the isolation of (+)-12methyltetradecanoic, 13-methyltetradecanoic and n-pentadecanoic acids by the combined processes of ester fractionation and low-temperature crystallization. The C13 acids were isolated from the same sample of butterfat by the use of similar procedures.
