Methymycin also derives from the condensation of propionate units whereas carbomycin derives from acetate condensation.

Some of the steps shown have not been fully elucidated. 7. -AA side chain characteristic of cephalosporin C. -AA moiety has the D- configuration in penicillin N and the L- configuration in isopenicillin N. 7 Biogenetic origin of cephalosporins. 8 Structure of penicillin N. 4 Gramicidin S The biosynthesis of this antibiotic is better known than that of the tyrocidins which it resembles, since it has been synthesised in a cell-free system which enables biosynthetic analysis of the steps to be made with relative ease.
