Phenolic lipid

Phenolic lipids are a class of natural products composed of long aliphatic chains and phenolic rings.[1] Phenolic lipids occur in plants, fungi and bacteria.

Bilobol, an alkylresorcinol found in Ginkgo biloba

Types

Biological activity

Due to their strong amphiphilic character, the phenolic lipids can incorporate into erythrocytes and liposomal membranes. The ability of these compounds to inhibit bacterial, fungal, protozoan and parasite growth seems to depend on their interaction with proteins and/or on their membrane-disturbing properties.[2]

Biological role

The phenolic lipid synthesis by type III polyketide synthases is essential for cyst formation in Azotobacter vinelandii.[3]

gollark: ```scheme(define actually-forgiving-grudge (lambda (x y) (let* ( (defection-count (length (filter (lambda (m) (= m 1)) x))) (lookback (+ 1 (inexact->exact (floor (expt 1.8 defection-count))))) (result (if (member '(1 0) (take lookback (zip x y))) 1 0)) ) result)))```I think this detects betrayals properly now.
gollark: Wow, BEE the memq function?
gollark: We are investigating MANY things.
gollark: This is quite complex, but here you go.
