amygdalin

 [ah-mig´dah-lin]
a glycoside from kernels and pits of bitter almonds, apricots, cherries, peaches, and apples, as well as certain other plant parts. Crushed and moistened residues release an enzyme that catalyzes a chemical reaction leading to release of hydrogen cyanide, so that excessive ingestion can be toxic. Preparations of amygdalin have been alleged to be anticancer agents, but this has never been scientifically proven. See also laetrile.

a·myg·da·lin

(ă-mig'dă-lin),
A cyanogenic glucoside present in almonds and seeds of other plants of the family Rosaceae; the principal component of laetrile. Emulsin splits amygdalin into benzaldehyde, d-glucose, and hydrocyanic acid.
Synonym(s): amygdaloside
[G. amygdala, almond, + -in]

amygdalin

/amyg·da·lin/ (-lin) a glycoside (l -mandelonitrile-β-gentiobioside) found in bitter almonds and other members of the same family; it is split enzymatically into glucose, benzaldehyde, and hydrocyanic acid. See also Laetrile and laetrile.

amygdalin

(ə-mĭg′də-lĭn)
n.
A glycoside, C20H27NO11, commonly found in seeds and other plant parts of many members of the rose family, such as kernels of the apricot, peach, and bitter almond, which breaks down into hydrocyanic acid, benzaldehyde, and glucose.

amygdalin

See Laetrile.

amygdalin

A beta-cyanogenic glycoside structurally related to the semisynthetic laetrile, which is obtained from the seeds of certain fruits (e.g., Prunus dulcis). Amygdalin has been (incorrectly) used as a synonym for Laetrile.

A β-cyanogenic glycoside structurally related to the semisynthetic laetrile, derived from the seeds of certain fruits. See Laetrile.

Historical Background of Amygdalin (Also known as Laetrile and Vitamin B17)
Laetrile therapy uses amygdalin, or vitamin B17, along with other nontoxic natural substances, to attack cancer, while at the same time supporting the healthy parts of the body.
