Lauric acid (dodekanoinska kiselina) je zasićena masna kiselina sa 12-ugljenika dugim lancom. Ona je beo prah sa slabim mirisom na Pimenta racemosa ili sapun.

Zastupljenost[uredi - уреди]

Laurinska kiselina je glavna kiselina u kokosovom ulju i u ulju palmine koštice (koje ne treba mešati sa palminim uljem),[6] i smatra se da ima antimikrobna svojstva.[7][8][9][10] Ona je takođe prisutna u ljudskom mleku (6.2% totalne masnoće), kravljem mleku (2.9%), i kozjem mleku (3.1%).[6]
