Here, we adopt the shorthand notation recommended by Liebisch et al. Briefly, fatty acyl chains are described by the total number of carbons, as indicated before the colon, and the total number of double bonds, as indicated after the colon. When present, the methyl branch functional group is abbreviated as "Me". Identified positions of methyl branching are shown within parenthesis after the integer indicating the number of double bonds. For example, 13-methlytetradecanoic acid, commonly referred to as isopentadecylic acid (iso 15:0), can be represented as FA 14:0(13Me). Similarly, 12-methlytetradecanoic acid, commonly referred to as anteisopentadecylic acid (anteiso 15:0), can be represented as FA 14:0(12Me).
