Acetyl
(gcide) | Acetyl \Ac"e*tyl\, n. [L. acetum vinegar + Gr. ? substance. See
-yl.] (Chem.)

carbon to three of hydrogen and one of oxygen. Its hydroxide
is acetic acid.

[WordNet 1.5] |
acetylcholine
(gcide) | acetylcholine \acetylcholine\ n.
1. a neurotransmitter released by the transmitting dendron at
autononmous synapses and at neuromuscular junctions. It is
a quaternary amine with an obligatory negative counterion.
The nominal formula for the hydroxide form is C7H17NO3.
Structural formula (CH3)3N(+)CH2CH2.O.CO.CH3.OH(-).
Note: Acetylcholine is the first recognized and best-studied
of the neurotransmitters. At receptors it is recycled
into choline by the action of acetylcholinesterase.
Acetylcholinesterase inhibitors therefore function as
nerve poisons. For biochemical studies it is prepared
typically in the chloride or bromide forms.
[WordNet 1.5 +PJC] |
acetylcholinesterase
(gcide) | acetylcholinesterase \acetylcholinesterase\ n.
1. an enzyme which exists in nerve cells and hydrolyses
acetylcholine into choline and acetic acid.
Note: It is essential for neurotransmission at autonomous
synapses and neuromuscular junctions, and its
inhibition by acetylcholinesterase inhibitors can
paralyze or kill an animal.
Syn: ACE

Acetylene
(gcide) | Acetylene \A*cet"y*lene\, n. (Chem.)
A gaseous compound of carbon and hydrogen, in the proportion
of two atoms of the former to two of the latter. It is a
colorless gas, with a peculiar, unpleasant odor, and is
produced for use as an illuminating gas in a number of ways,
but chiefly by the action of water on calcium carbide. Its
light is very brilliant. --Watts.

acetyl-propionic
(gcide) | Levulinic \Lev`u*lin"ic\ (-l[i^]n"[i^]k), a. (Chem.)

diacetyl morphine
(gcide) | heroin \her"o*in\ (h[~e]r"[-o]*[i^]n), n. (Chem.)
a morphine derivative, diacetyl morphine, used to relieve
severe pain and as a sedative. It is highly addictive, and
its use is strictly controlled in the U.S. by federal law. It
is a popular strong narcotic drug of abuse, in part because
it is more soluble than morphine. It is sometimes included as
one of the components of Brompton's mixture, used to control
pain in terminallly ill patients.
Syn: diacetyl morphine, H, horse, junk, scag, shit, smack.
