ChlorophyllName comes from the Greek language:Chloros means fresh green + Phyllon means leaf |
|
Chlorine pigment come in six variations A = C55H72O5N4Mg - B = C55H70O6N4Mg - C1 = C35H30O5N4Mg C2 = C35H28O5N4Mg - D = C54H70O6N4Mg - F = C55H70O6N4Mg ![]() The oldest but discovered in 2010 is Chlorophyll f Cyanobacteria are oxygenic microorganisms that form stromatolites ![]() ![]() Cyanobacteria use water, carbon dioxide, and sunlight to create their food. They live on stromatolites and are the oldest oxygen producers we know of. The earliest stromatolite of confirmed microbial origin dates to 3.4 billion years ago. Without the oxygen production of cyanobacteria on stromatolites Earth would be very different! Chlorophyll is a chlorin pigment. Its structure is very similar to heme, but at the center of the chlorine ring is a magnesium ion Mg. (Hemes are most commonly recognized in their presence as components of hemoglobin. As you know, hemoglobin does very effectively deliver oxygen to human tissues, its in every mammals blood - that's the reason we talk about a great plan in Nature) This is a close-up of chlorophyll ![]() Why does chlorophyll look green? ![]() Using Spectrophotometry measuring the absorbance spectra of free chlorophyll a (green) and b (red) we clearly can see that red and blue is absorbed, but green is not absorbed, green light is reflected. That is the reason we see leaves in a green color. Why is chlorophyll so important? Today, almost all life on Earth needs oxygen. Today, almost all life on Earth depends on plant growth (If you think different, just email us) Chlorophyll is the main oxygen factory on Earth!! Almost all life on Earth needs food Nature = food = survival for life on Earth Now you know, why we work as volunteers for an international Nature Conservation group. Please feel invited and very welcome to join us!! |
