chloroplast |
Photosynthetic organelle of higher plants. Lens shaped and rather variable in size but approximately 5m long. Surrounded by a double membrane and contains circular DNA though not enough to code for all proteins in the chloroplast). Like the mitochondrion, it is semi autonomous. It resembles a cyanobacterium from which, on the endosymbiont hypothesis, it might be derived. The photosynthetic pigment, chlorophyll, is associated with the membrane of vesicles (thylakoids) that are stacked to form grana. (18 Nov 1997) |

chloroprene |
<chemical> 2-chloro-1,3-butadiene. Toxic, possibly carcinogenic, monomer of neoprene, a synthetic rubber; causes damage to skin, lungs, CNS, kidneys, liver, blood cells and foetuses. Synonym: 2-chlorobutadiene. Chemical name: 1,3-Butadiene, 2-chloro- (12 Dec 1998) |
chloroprocaine hydrochloride |
Beta-Diethylaminoethyl-2-chloro-4-aminobenzoate hydrochloride;a local anaesthetic similar in action and use to procaine hydrochloride. (05 Mar 2000) |
chloroprocaine penicillin O |
A crystalline salt of 2-chloroprocaine and penicillin O, insoluble in water; the level of the antibiotic in the blood persists for 24 hours; its antibacterial activity is similar to that of penicillin O and G. (05 Mar 2000) |
chloropropamide |
<drug> An oral hypoglycemic agent (a prescription drug that people take to lower the level of glucose in the blood). The pills work for some people whose pancreas still makes some insulin. They can help the body in several ways, such as by causing the cells in the pancreas to release more insulin. (09 Oct 1997) |
chloropsia |
A condition in which objects appear to be coloured green, as may occur in digitalis intoxication. Synonym: green vision. Origin: chloro-+ G. Opsis, eyesight (05 Mar 2000) |
chloropyramine |

chloroquine |
<drug> Antimalarial drug that has the interesting property of increasing the intralysosomal pH when added to intact cells in culture. (18 Nov 1997) |
chloroquinolinols |
<chemical> 8-hydroxyquinolinols chlorinated on the number 5 and/or 7 carbon atom(s). They are antibacterial, antiprotozoal, and antidiarrhoeal, especially in amebiasis, and have also been used as antiseborrheics. The compounds are mostly used topically, but have been used also as animal feed additives. They may cause optic and other neuropathies and are most frequently administered in combination with other agents. Pharmacological action: amebicides. (12 Dec 1998) |
chlorosis |
Yellowing or bleaching of plant tissues due to the loss of chlorophyll or failure of chlorophyll synthesis. Symptomatic of many plant diseases, also of deficiencies of light or certain nutrients. (18 Nov 1997) |
chlorosome |
<cell biology> Elongated membranous vesicles attached to the plasma membrane of green photosynthetic bacteria, contain the light harvesting antenna complexes of bacteria in the sub Order Chlorobiineae. Pigments include bacteriochlorophylls and carotenoids. Origin: Gr. Soma = body (18 Nov 1997) |
