Zastupljenost
urediLaurinska kiselina je glavna kiselina u kokosovom ulju i u ulju palmine koštice (koje ne treba mešati sa palminim uljem),[4] i smatra se da ima antimikrobna svojstva.[5][6][7][8] Ona je takođe prisutna u ljudskom mleku (6.2% totalne masnoće), kravljem mleku (2.9%), i kozjem mleku (3.1%).[4]
