Overview
The molecular structure of chlorophyll a is connected by 4 pyrrole (= CH-), referred to as porphyrin (side on the ring). chain). One magnesium atom was bonded in the center of the porphyrin ring, and a cyclopentanone (V) was esterified by levhol (C20H39OH, molecular weight 893) on the cyclo-alcohol (C20H39OH, molecular weight 893). Water solubility after saponification.
In an acidic environment, the magnesium in the porphyrin ring can be substituted by H, referred to as determination of magnesium, brown, and the color is turned green, this color is turned green. Stable, do not fade under the light, nor is it destroyed for acid, and the preservation of the plant specimens is to take advantage of this property.
In photosynthesis, most of the chlorophyll effect is to absorb and transfer light energy, only a very small amount of chlorophyll A molecules to switch light energy. They are probably bonded to the protein in a living body, existing on the cyset membrane film.

The main function
1. Chlorophyll A and B can absorb light can. However, only a few chlorophyll a in an excitation state can convert light energy into electric energy
2. The ratio of certain chlorophyll a and chlorophyll B reflects how much plant is used for light energy.
, such as the ratio of the chlorophyllium B and chlorophyll b, and the ratio of glutinite chlorophyll a and chlorophyll b is small.
Physiological action
The chlorophyll a in the plant has a positive role in the human body except for photosynthesis.
The largest plant non-spiraculina containing the corneum containing the corneum, which is mainly chlorophyll a, which is 2-3 times the chlorophyll of other plants. In addition, the spiral chlorophyll molecules contain porphyrins, which are structurally similar to the hemoglin of the human animal, and is the direct material of human and animal heme, so chlorophyll a is "green blood". It is also a rich iron element in spirulina, so the perfect combination of chlorophyll a and iron elements in spiral algae is the best partner for treating iron deficiency anemia.
