From: Dynamics of sterol synthesis during development of Leishmania spp. parasites to their virulent form
Representative gas chromatography spectra (GC) of total sterols of Leishmania infantum virulent and avirulent strains cultured in complete HOMEM or serum-free medium (SFM). Shaded peaks were identified as sterols with relative retention time to cholesterol as marked. 1.000-Cholesterol; 1.030-Zymosterol; 1.069-Ergosterol – I; 1.078-Ergosta-7,22-dien-3β-ol – I; 1.086-Ergostatetraenol; 1.115-Ergosterol – II; 1.131-Ergosta-7,22-dien-3β-ol – II; 1.157-Lanosterol; and 1.229-Stigmasta-7,24(28)-dien-3β-ol. a Stationary promastigotes of virulent strain cultured in HOMEM. b Stationary promastigotes of avirulent L5 strain cultured in HOMEM. c Stationary promastigotes of virulent strain cultured in SFM. The GC spectra of metacyclic promastigotes had been previously published [8]
