WebPheophytin forms showed no clear pattern, although pheo- . phytin a2 was more abundant in laboratory experiments than in field samples. The total mass concentration of pheophorbide forms was four times higher, on average, than that of pheophytin forms (n = 64). Because of their field distributions, the more polar may be the more degraded WebDec 6, 2024 · Lipopolysaccharide-Induced Nitric Oxide, Prostaglandin E2, and Cytokine Production of Mouse and Human Macrophages Are Suppressed by Pheophytin-b Lipopolysaccharide-Induced Nitric Oxide, Prostaglandin E2, and Cytokine Production of Mouse and Human Macrophages Are Suppressed by Pheophytin-b Authors

In biochemical terms, pheophytin is a chlorophyll molecule lacking a central Mg ion. It can be produced from chlorophyll by treatment with a weak acid, producing a dark bluish waxy pigment. The probable etymology comes from this description, with pheo meaning dusky and phyt meaning vegetation.
