“…Only linseed oil, with a U/S 12.7, had a very high oxidation index. The reason was considered to be due to the abundant content of the linolenic acid residual groups that undergo oxidation relatively easily because they have two bisallylic positions in the chain (12). Generally, it is known that the oxidizability of polyunsaturated aliphatic compounds in homogeneous solutions is dependent on the number of bisallylic positions available for oxidation (13).…”
