What's the difference between chlorophyll and phylloxanthin?

Chlorophyll

Definition:

(n.) Literally, leaf green; a green granular matter formed in the cells of the leaves (and other parts exposed to light) of plants, to which they owe their green color, and through which all ordinary assimilation of plant food takes place. Similar chlorophyll granules have been found in the tissues of the lower animals.

Example Sentences:

(1) Results obtained show that chlorophyll is more active than other inhibitors studied and suggest a higher surface adsorption intensity on the primary sources of the crystal surface.
(2) Upon illumination, a dark-adapted photosynthetic sample shows time-dependent changes in chlorophyll (Chl) a fluorescence yield, known as the Kautsky phenomenon or the OIDPS transient.
(3) As both chlorophyll a and b accumulate, extensive formation of grana takes place.
(4) In dark-grown cells adapting to the light in resting medium and in an X-ray-induced mutant, D(o) is proportional to the chlorophyll content of the cells.
(5) Luminescence yield, absorption spectra and molecular weight dependence of chlorophyll in methylethylketone and n-hexane on concentration was investigated.
(6) The derivative absorption spectra of adsorbed chlorophyll a have been obtained.
(7) An in vitro translation system using lysed etioplasts was developed to test if the accumulation of plastid-encoded chlorophyll a apoproteins is dependent on the de novo synthesis of chlorophyll a.
(8) Measurements of chlorophyll a fluorescence decay kinetics after the second saturating actinic flash indicated that, after formate treatment, the halftime of QA- oxidation was decreased by approximately a factor of 2, 4 and 6 in the wild type, R251S and R233Q, respectively.
(9) Highest activities in darkness have been observed at times when maximum chlorophyll formation would have occurred had the plants been exposed to light.
(10) DBcAMP* showed a positive effect on chlorophyll synthesis and growth rate at much lower concentrations compared to cAMP.
(11) One of them seems to be correlated with chlorophyll derivatives.
(12) In presence of vanadium, the chlorophyll formation was stimulated in Scenedesmus obliquus.
(13) The apparent molecular weight of the chlorophyll-protein complexes I and II are 88,000 and 28,000, respectively.
(14) This change is ascribed to the irreversible oxidation of a dimeric chlorophyll molecule which acts as electron donor to P+-680 under these conditions.
(15) The potential was found to shift to a less noble state when the system of the chlorophyll-naphthoquinone electrode was inserted into NAD solution with illumination.
(16) Analyses included measurement of chlorophyll autofluorescence and fluorescence due to uptake of fluorescein diacetate (FDA) and calcofluor white M2R (CFW).
(17) Chlorophyllase (chlorophyll chlorophyllidohydrolase, EC 3.1.1.14) activity assays that are based on the determination of this chlorophyllide fluorescence show that phosphatidylglycerol (PG), and also sulphoquinovosyldiacylglycerol (SQDG), associate with isolated chlorophyllase, thereby inactivating the enzyme in a co-operative way.
(18) Resonance Raman spectra of the pi-cation of bacterio-chlorophyll a in solution at 30 K are reported and discussed.
(19) This evidences for the significance of the reaction system organization for interaction of chlorophyllase with chlorophyll.
