Application


  • Isolation of methyl gamma linolenate from Spirulina platensis using flash chromatography and its apoptosis inducing effect.: This study explores the extraction and potential anticancer effects of methyl gamma-linolenate from Spirulina platensis by using it as a standard for identification, suggesting its use in developing natural anticancer compounds (Jubie et al., 2015).

Biochem/physiol Actions

Methyl γ-linolenate (C18:6,9,12) differs from methyl α-linolenate (C18:9,12,15) in the positions of the double bonds. Methyl γ-linolenate may be used in nutritional studies regarding weight regain and as a possible tumor suppression agent.
