Separation of Chlorophyll Pigm
Autotrophs, organisms that produce their own food, utilize certain pigments to carry out photosynthesis. The most important of these is chlorophyll a, for it passes the energized electrons to the molecules that produce glucose. Seventy-five percent of chlorophyll in green plants is chlorophyll a. Chlorophyll a is green.Chlorophyll b is also an important type of chlorophyll, but unlike chlorophyll a, it is not vital to photosynthesis. Chlorophyll b is found in green algae and certain plants, it is yellow green. Chlorophyll b absorbs light of a different wavelength than chlorophyll a, but ultimately transfers it to chlorophyll a for conversion into chemical energy. Chromatography is a technique used to separate mixtures of compounds. There are many different types of Chromatography, including: paper chromatography, ion concentration chromatography, gas-liquid chromatography, thin layer chromatography, partition chromatography and gel-permeation chromatography. Chromatography consists of two phases: the stationary phase and the mobile phase. The stationary phase consists of a stationary item which allows the molecule
