Lasso cell (Zool.), One of a peculiar kind of defensive and offensive stinging cells, found in great numbers in all c[oe]lenterates, and in a few animals of other groups. They are most highly developed in the tentacles of jellyfishes, hydroids, and Actini[ae]. Each of these cells is filled with, fluid, and contains a long, slender, often barbed, hollow thread coiled up within it. When the cell contracts the thread is quickly ejected, being at the same time turned inside out. The thread is able to penetrate the flesh of various small, soft-bodied animals, and carries a subtle poison by which they are speedily paralyzed and killed. The threads, at the same time, hold the prey in position, attached to the tentacles. Some of the jellyfishes, as the Portuguese man-of-war, and Cyanea, are able to penetrate the human skin, and inflict painful stings in the same way. Called also nettling cell, cnida, cnidocell.

Compare: Ketone
Ketone (n.) (Chem.) One of a large class of organic substances resembling the aldehydes, obtained by the distillation of certain salts of organic acids and consisting of carbonyl ({CO) united with two hydrocarbon radicals. In general the ketones are colorless volatile liquids having a pungent ethereal odor.
Note: The ketones are named by adding the suffix-one to the stems of the organic acids from which they are respectively derived; thus, acetic acid gives acetone; butyric acid, butyrone, etc.
Compare: Acyl
Acyl (n.) (Org. Chem.) An acid radical, as acetyl, malonyl, or benzoyl. An acyl radical can be depicted as R-CO-, where -CO- is the carbonyl group, and R is the group that characterizes the acyl moiety.
Carbonic (a.) (Chem.) Of, pertaining to, or obtained from, carbon; as, carbonic oxide.
Carbonic acid (Chem.), An acid HO.CO.OH, not existing separately, which, combined with positive or basic atoms or radicals, forms carbonates. In common language the term is very generally applied to a compound of carbon and oxygen, CO2, more correctly called carbon dioxide. It is a colorless, heavy, irrespirable gas, extinguishing flame, and when breathed destroys life. It can be reduced to a liquid and solid form by intense pressure. It is produced in the fermentation of liquors, and by the combustion and decomposition of organic substances, or other substances containing carbon. It is formed in the explosion of fire damp in mines, and is hence called after damp; it is also know as choke damp, and mephitic air. Water will absorb its own volume of it, and more than this under pressure, and in this state becomes the common soda water of the shops, and the carbonated water of natural springs. Combined with lime it constitutes limestone, or common marble and chalk. Plants imbibe it for their nutrition and growth, the carbon being retained and the oxygen given out.
Carbonic oxide (Chem.), A colorless gas, CO, of a light odor, called more correctly carbon monoxide. It is almost the only definitely known compound in which carbon seems to be divalent. It is a product of the incomplete combustion of carbon, and is an abundant constituent of water gas. It is fatal to animal life, extinguishes combustion, and burns with a pale blue flame, forming carbon dioxide.
Carbonyl (n.) (Chem.) The radical ({=CO), occuring, always combined, in many compounds, as the aldehydes, the ketones, urea, carbonyl chloride, etc.
Note: Though denoted by a formula identical with that of carbon monoxide, it is chemically distinct, as carbon seems to be divalent in carbon monoxide, but tetravalent in carbonyl compounds.
Carbonyl chloride (Chem.), A colorless gas, COCl2, of offensive odor, and easily condensable to liquid. It is formed from chlorine and carbon monoxide, under the influence of light, and hence has been called phosgene, or phosgene gas; -- called also carbon oxychloride. It is used in chemical synthesis, and was also used as a poison gas in World War I.
Co (n.) The chemical formula for cobalt, a ferromagnetic metal of atomic number 27.
Syn: cobalt, atomic number 27.
