Some Properties of , Carotenoidsvertheless it should be pointed out that simple characterizations such as “stable” or “labile” have lost much of their meaning in the class of multiconjugated systems. Because the degree of the double bond character is subject to considerable variation along the chain, the extent of liability of a gmyriad 发表于 2025-3-22 01:51:21
