Fig. 7From: An extract from the frass of swallowtail butterfly (Papilio machaon) larvae inhibits HCT116 colon cancer cell proliferation but not other cancer cell typesThe predicted metabolic process for the metabolites derived from host plants. P. machaon larvae eat host plants, and their metabolic enzymes, CYPs, change the structure of compounds included in the host plant tissues. The metabolites from the host plants undergo conversion of their biological activity through the P. machaon larval metabolic processBack to article page
