Chlorophyll molecule. Computer model of the photoreceptor molecule chlorophyll a (C55.H72.Mg.N4.O5) found in green plants. The atoms are colour-coded (key at lower right): carbon (C,grey); oxygen (O,red); hydrogen (H,yellow); magnesium (Mg,green); and nitrogen (N,blue). The central part of the molecule is the porphyrin ring (top) surrounding a central magnesium atom. It is the arrangement of the electrons in this ring that traps the energy in sunlight during photosynthesis. Chlorophyll a is the major type. The minor type,chlorophyll b,has a CHO group replacing a CH3 group (top,white inset circles) | |
