Gentamicin, sold under brand names Garamycin among others, is an antibiotic used to treat several types of bacterial infections. This may include bone infections, endocarditis, pelvic inflammatory disease, meningitis, pneumonia, urinary tract infections, and sepsis among others. It is not effective for gonorrhea or chlamydia infections. It can be given intravenously, by injection into a muscle, or topically. Topical formulations may be used in burns or for infections of the outside of the eye. I
All of the other chlorophylls and carotenoids involved in light absorption are referred to as accessory pigments. Another kind of accessory pigment found in some groups of algae and photosynthetic bacteria are the phycobili proteins, which may impart a red or blue color to the cells in which they occur.
The color of the pigment comes from the wavelengths of light that are reflected, or in other words, those wavelengths not absorbed. Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. This is why plants appear green to us.Black pigments absorb all wavelengths of visible light that strike them. White pigments reflect most of the wavelengths striking them.Each pigment has a characteristic absorption spectrum describing how it absorbs or reflects different wavelengths of light.his is why plants appear green to us.
