Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about The β-carotene-oxygen copolymer: Its relationship to apocarotenoids and β-carotene function. Author is Mogg, Trevor J.; Burton, Graham W..
β-Carotene spontaneously copolymerizes with mol. oxygen to form a β-carotene-oxygen copolymer compound (“”copolymer””) as the main product, together with small amounts of many apocarotenoids. Both the addition and scission products are interpreted as being formed during progression through successive free radical β-carotene-oxygen adduct intermediates. The product mixture from full oxidation of β-carotene, lacking both vitamin A and β-carotene, has immunol. activities, some of which are derived from the copolymer. However, the copolymer’s chem. makeup is unknown. A chem. breakdown study shows the compound to be moderately stable but nevertheless the latent source of many small apocarotenoids. GC-MS anal. with mass-spectral library matching identified a min. of 45 structures, while more than 90 others remain unassigned. Newly identified products include various small keto carboxylic acids and dicarboxylic acids, several of which are central metabolic intermediates. Also present are glyoxal and Me glyoxal dialdehydes, recently reported as β-carotene metabolites in plants. Although both compounds at higher concentrations are known to be toxic, at low concentration, Me glyoxal has been reported to be potentially capable of activating an immune response against microbial infection. In plants, advantage is taken of the electrophilic reactivity of specific apocarotenoids derived from β-carotene oxidation to activate protective defenses. Given that the copolymer occurs naturally and is a major product of non-enzymic β-carotene oxidation in stored plants, by partially sequestering apocarotenoid metabolites, the copolymer may serve to limit potential toxicity and maintain low cellular apocarotenoid concentrations for signaling purposes. In animals, the copolymer may serve as a systemic source of apocarotenoids.
