Mode of Action: The product acts in three ways: Glutamine is an essential energy source for most mammalian cells in culture due to its amino acid carbon skeleton. Penicillin inhibits bacterial cell wall synthesis. Streptomycin inhibits prokaryote protein synthesis by preventing the transition from initiation complex to chain-elongating ribosome, causing miscoding.
