Receptors for common SCFA and their related interaction.

Receptors	Interaction	References
GPR41/FFAR3	It has more affinity with propionate and least with acetate.	Koh et al. (2016)
GPR43/FFAR2	It has more affinity with propionate and acetate and least affinity with butyrate.	Mandaliya and Seshadri (2019)
GPR109A/HCAR2	Butyrate has attraction with GPR109A or HCAR2.	Dalile et al. (2019)

SCFA = short chain fatty acids; GPR = G protein-coupled receptor; FFAR = free fatty acid receptor; HCAR2 = hydroxycarboxylic acid receptor 2.
