Chlorophyll

Chlorophyll research papers Many research in the field of cancer research opens up new possibilities for therapeutic and preventive measures. One area of ​​research is the influence of chlorophyll on human cancer cells. Research is under way to investigate whether chlorophyll has important anti-cancer factors that may play a role in cancer cell destruction, or whether it is an effective prophylactic agent. Due to the increased human exposure to environmental toxins, genotoxicity has been reduced in studies of naturally occurring plant products (Sarkar, 1994).

Chlorophyll is a complex molecule. Several modifications of chlorophyll occur in plants and other photosynthetic organisms. All photosynthetic organisms have chlorophyll a. The auxiliary pigment absorbs energy which chlorophyll a does not absorb. Supplementary dyes include chlorophyll b (c, d and e in algae and protists), lutein and carotenoids (such as beta carotene). Chlorophyll a absorbs energy from the purple blue and red orange red wavelengths, but the energy absorbed from the medium (green - yellow - orange) wavelength is very small.

Green plant is green because it contains pigment called chlorophyll. Chlorophyll absorbs light of a specific wavelength in the visible spectrum. As detailed in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and blue (short wavelength) regions of the visible spectrum. The green light is reflected without being absorbed and the plant appears green. The absorption spectrum shows how different side chains in chlorophyll a and chlorophyll b result in slightly different absorption of visible light. Light having a wavelength of 460 nm is not significantly absorbed by chlorophyll a, but is trapped by chlorophyll b, and chlorophyll b is strongly absorbed at this wavelength. Two chlorophylls of plants complement each other as they absorb sunlight. Plants can meet energy demand by absorbing light from the blue and red parts of the spectrum

Only chlorophyll a is directly involved in the photoreaction of photosynthesis. Chlorophyll b helps chlorophyll a capture light energy and is called an auxiliary pigment. Supplementary dyes allow plants to capture more light energy by absorbing colors that chlorophyll a can not absorb. Another group of auxiliary pigments contained in thylakoid membranes, called carotenoids, include yellow, red, and orange pigments that can be colored for carrots, bananas, pumpkins, flowers, and autumn leaves. Green leaf carotenoids are usually covered with chlorophyll until fall chlorophyll decomposition
