Fig. 8From: Tracing the biosynthetic origin of limonoids and their functional groups through stable isotope labeling and inhibition in neem tree (Azadirachta indica) cell suspensionTracing the flow of 13C carbon from [1-13C] /[1,6-13C] Glc through primary metabolic pathway for the formation of functional groups present in limonoids. (a) tiglate group present in azadirachtin and salannin is traced through isoleucine biosynthetic pathways. (b) isovalerate group present in salannolacetate is traced through leucine biosynthetic pathwayBack to article page
