Phytomonic acid is a saturated fatty acid found mainly in a gram-negative bacteria, L. arabinosus, but also in protozoa and in the seed oil of B. coccineus (Connaraceae). Its cyclopropane ring structure has some properties of a double bond, and it may serve to regulate cell membrane fluidity.

Phytomonic acid is a long-chain fatty acid containing a cyclopropane ring produced by Lactobacillus reuteri. Lactobacilli that normally produce Lactobacillic acid also have the ability to resist TNF-α[1].
