Pheophytin chemical structure
WebPheophytin is a darker pigment with 10% higher specific absorbance at 665 nm compared to pheophorbide. Pheophytin is black and pheophorbide is brown; therefore, their relative … WebIn biochemical terms, pheophytin is a chlorophyll molecule lacking a central Mg 2 + 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. What is the Colour of pheophytin?
