Metabolic pathway for biosynthesis of mycobacterial galactan. The pathway can be followed by in vitro reaction using mycobacterial enzyme fractions and UDP-[14C] Galp as a tracer. Glycolipids GL-1 to GL-5 are extracted into CHCl3–CH3OH (2:1), and lipid-linked galactan polymer into more polar solvents.
