It is involved in photosynthesis, which is the process by which light energy is converted to chemical energy through the synthesis of organic compounds: it absorbs energy from light; this energy is then used to convert carbon dioxide to carbohydrates. Pure chlorophyll appears as waxy dark green to black crystals. Chlorophyll has been used as a green colorant in clothing, soaps, leathers, waxes, foods, liquors, and perfumes. It is also used as a sensitizer for color film and as a deodorizer. ]]></note></mads>
