Biochem/physiol Actions

19-Methyleicosanoic acid (19-MEA) is related to 18-methyleicosanoic acid (18-MEA), a fatty acid found covalently associated with fur and hair. 19-Methyleicosanoic acid may be used in comparative studies with 18-MEA and other methyleicosanoic acids that affect hair and fur fiber structure. 19-MEA may be studied for use as a component of hair treatment medications and formulations.
