From equation 1 Instead of the wave-lengths determined by these researchers, 662, 646 and 470 nm at which we ob-served maximum absorbance were used. Unfortunately, the Arnon equations are not particularly accurate (Porra, 2002). Its color is yellow, and it primarily absorbs blue light. blue-violet and red. More specifically, chlorophyll molecules are described as photoreceptors due to their light absorption properties. E. aureum and F. benjamina), cut into pieces measuring approximately 2 cm x 2 cm The head is hydropilic and the tail is lipophilic. The formulas were showed in Table 1. Unfortunately, the Arnon equations are not particularly accurate (Porra, 2002). Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. The large dip in the middle of the graph near the green wavelengths is due to chlorophyll reflecting, instead of absorbing, green light. The 3 rd carbon of the side group is methyl group (-CH3) 6. Besides its importance in photosynthesis, chlorophyll is probably the most-often used estimator of algal biomass in lakes and streams, at least in North America. Für Chlorophyll a ist sie in der Abbildung noch zu erkennen, für Chlorophyll b verschwindet sie im Untergrund. C55H72MgN4O5.
