chlorophyll

 [klor´o-fil]
any of a group of green pigments, containing a magnesium-porphyrin complex, that are involved in oxygen-producing photosynthesis. Preparations of water-soluble chlorophyll derivatives are sometimes applied topically for deodorization purposes. They may also be administered orally to deodorize ulcerative lesions as well as urine and feces in colostomy, ileostomy, or incontinence.

chlor·o·phyll

(klōr'ō-fil),
The magnesium complex of the phorbin derivative found in photosynthetic organisms; light-absorbing green plant pigments that, in living plants, convert light energy into oxidizing and reducing power, thus fixing CO2 and evolving O2; the naturally occurring forms are chlorophyll a, b, c, and d.
See also: phorbin.

chlorophyll

/chlo·ro·phyll/ (klor´o-fil) any of a group of green magnesium-containing porphyrin derivatives occurring in all photosynthetic organisms; they convert light energy to reducing potential for the reduction of CO2. Preparations of water-soluble chlorophyll salts are used as deodorizers; see chlorophyllin.

chlorophyll

(klôr′ə-fĭl)
n.
Any of a group of green pigments that capture light energy used as the energy source in photosynthesis and that are found in the chloroplasts of plants and other photosynthetic organisms such as cyanobacteria, especially:
a. A waxy blue-black microcrystalline green-plant pigment, C55H72MgN4O5, with a characteristic blue-green alcohol solution. Also called chlorophyll a.
b. A similar green-plant pigment, C55H70MgN4O6, having a brilliant green alcohol solution. Also called chlorophyll b.

chlo′ro·phyl′lous adj.

chlorophyll

[klôr′əfil]
Etymology: Gk, chloros + phyllon, leaf
one of several pigments that absorb light energy and participate in the production of carbohydrates in photosynthetic organisms. Chlorophylls a and b are found in plants, chlorophyll c occurs in brown algae, and chlorophyll d occurs in red algae. Chlorophyll molecules contain a porphyrin ring system that binds a central magnesium ion. See also photosynthesis.

chlorophyll

Biology
The green plant pigment pivotal in photosynthesis, the manufacture of carbohydrates from CO2 and H2O.

Fringe nutrition
While chlorophyll resembles haemoglobin chemically, it has no role in human metabolism; there is, therefore, no basis for using chlorophyll to treat allergies, anaemia, arthritis, colitis, coughs, hypertension, infections, ulcers, and many other conditions, as has been recommended by some alternative medical practitioners.

chlor·o·phyll

(klōr'ō-fil)
A complex of light-absorbing green pigments that, in living plants, convert light energy into oxidizing and reducing power, thus fixing CO2 and evolving O2; the naturally occurring forms are chlorophyll a, b, c, and d.

chlorophyll

a group of pigments giving a green coloration to most plants, which is found in any part of the plant that is exposed to sunlight. The pigments are usually contained in cell organelles called CHLOROPLASTS. Chlorophyll is a PORPHYRIN containing magnesium and exists in several forms which have different side chains. Typically, chlorophylls a (blue-green) and b (yellow-green) are found in higher plants; chlorophylls c and d are found in algae. Chlorophyll has the vital function of absorbing light energy for PHOTOSYNTHESIS. see ACTION SPECTRUM. A related pigment, BACTERIOCHLOROPHYLL, containing manganese instead of magnesium, is found in photosynthetic bacteria.

chlorophyll (klōˑ·rō·fil),

n a nontoxic plant pigment used in the treatment of pelvic inflammatory disease, to promote production of erythrocytes and hemoglobin, and to facilitate tissue regeneration. Used by plants to make energy from sunlight.

chlorophyll

any of a group of green pigments, containing a magnesium-porphyrin complex, that are involved in oxygen-producing photosynthesis in plants. Preparations of water-soluble chlorophyll derivatives are applied topically for deodorization of skin lesions and to stimulate healing. It is also administered orally to deodorize ulcerative lesions and the urine and feces.
A chlorophyll metabolite, phylloerythrin, is the common photodynamic agent in pastured animals with liver damage. The phylloerythrin accumulates because its excretory pathway is the biliary system.

Pteridophyte spore viability depends on spore type, chlorophyllous and non-chlorophyllous, or taxonomic group (Lloyd and Klekowski, 1970).
Lloyd and Klekowski (1970) have made comparisons between the viability of chlorophyllous and non-chlorophyllous spores of several species of ferns; they observed that spores with chloroplasts germinate more rapidly than spores without chloroplasts (within one or two days after sowing), but this ability to germinate declines rapidly with their age.
The choice of this subcosmopolitan species with chlorophyllous spores derives from the observation of its increasing decline in Italy, especially considering the fragmentation and isolation of its populations in Central Italy (Landi and Angiolini, 2007).
We report the first results of in vitro reproduction of Osmunda regalis using spores taken from exsiccata, providing new information on the viability of chlorophyllous spores, and useful data to further research on the best conditions and procedures for long-term conservation in germplasm banks.
We are continuing research on the development of tests with spores from various herbaria (CAG, FI, SIENA), selected from exsiccata with different age, chosen at regular intervals, to confirm the correlation between age and longevity of chlorophyllous spores under the same disinfestation treatments.
