Additionally, GPR120 has been implicated to be involved in the ability to taste fats.  It is expressed in taste bud cells (specifically cell type II, which contain other G-protein coupled taste receptors), and its absence leads to reduced preference to two types of fatty acid (linoleic acid and oleic acid), as well as decreased neuronal response to oral fatty acids.
