Abstract
Eight sugars have been isolated from preparations of mycoside C, a mixture of glycolipids produced by strains of Mycobacterium avium. The sugars of mycoside C were identified as glucose, arabinose, rhamnose, 3-O-methylrhamnose, 2,3- and 3,4-di-O-methylrhamnose, 6-deoxytalose and 3-O-methyl-6-deoxytalose. One purified component of the glycolipid mixture contained only 6-deoxytalose, 3-O-methyl-6-deoxytalose, 3,4-di-O-methylrhamnose and a small amount of 3-O-methylrhamnose. The "K" lipopolysaccharide antigen of Pseudomonasi pseudomallei also contains 6-deoxytalose.
