WebThese are the two important differences that you will observe in the TH-NMR of the product compared to the starting materials. methyl linoleate & methyl a-linoleate have bis-allylic protons. The ratio of integrals of methoxy protons to the bis-allylic protons in FAMEs, gives a strong indication of the identity of the oil Oil Canola Olive ... WebAug 9, 2016 · PUFAs are highly susceptible to oxidative damage due to the presence of bis-allylic protons that are vulnerable to hydrogen atom abstraction (Fig. 2D). Hydrogen abstraction produces alkyl radicals that react readily with molecular oxygen to produce peroxyl radicals, which subsequently react with other PUFAs to propagate a chain …
