"$", numeric character reference: "$", Common
names: ITU-T: dollar sign. Rare: currency symbol; buck; cash;

Well-known uses of the dollar symbol in computing include as a
prefix on the names of string variables in BASIC, shell
and related languages like Perl. In shell languages it is also
used in positional parameters so "$1" is the first parameter to
a shell script, "$2" the second, etc. In a regular expression,
$ matches the end of the string.

C21H36N7O16P3S
(gcide) | coenzyme A \co*en"zyme A`\ (k[-o]*[e^]n"z[imac]m [=a]`),
(Biochem.)
a coenzyme (C21H36N7O16P3S) that participates in the
transfer of acetyl groups in biochemical reactions; --
abbreviated CoA. It contains adenosine, phosphate,
pantothenic acid and cysteamine groups. The acetyl group to
be transferred during biosynthesis is temporarily attached to
the free sulhydryl of the cysteamine group to form a
thioester, in which state it is called acetyl coenzyme A. The
strength of a preparation of coenzyme A may be expressed by
the Lippman unit; one milligram of CoA contains 413 Lippman
units.

1. one of several antibiotic substances produced by several
species of Streptomyces, active against various fungi.
They are used only experimentally, not in medicine. The
two best-known antimycins are antimycin A1 (C28H40N2O9)

their mechanism of action, interference with the proton
pumping mechanism of fungi.

glycoside, which is the essential ingredient of the
extracts of foxglove. It is a white, crystalline

diglucoside of a steroid. It is a powerful cardiac
stimulant and is used as a cardiotonic for treatment
of certain heart conditions, such as congestive heart
failure. Chemically it is

(22)-enolide. The related compounds digitoxin and
digoxin are also extracted from the foxglove. The
class of steroid glycosides having cardiotonic
properties are refered to as the cardiac glycosides.
