Gramcidins are 15 residue peptides with alternating D and L amino acids, which assemble inside of the hydrophobic interior of the cellular lipid bilayer to form a \u03b2-helix. Active against most Gram-positive bacteria and some Gram-negative organisms, Gramicidin D is used primarily as a topical antibiotic and is also found in Polysporin ophthalmic solution."}]
