ceramide

 [ser´ah-mīd]
the basic unit of the sphingolipids, consisting of sphingosine or a related base attached via its amino group to a long-chain fatty acid anion. Ceramides accumulate abnormally in farber's disease.
ceramide glucoside the major sphingolipid accumulated in Gaucher's disease.
ceramide lactosidosis a sphingolipidosis in which ceramide lactoside accumulates in neural and visceral tissues owing to a deficiency of a β-galactosidase.
ceramide trihexoside the major sphingolipid accumulated in Fabry's disease.

cer·a·mide

(ser'ă-mīd),
Generic term for a class of sphingolipid, N-acyl (fatty acid) derivatives of a long chain base or sphingoid such as sphinganine or sphingosine; for example, CH3(CH2)12CH=CH-CHOH-CH(CH2OH)-NH-CO-R, where R is the fatty-acyl residue, attached in this example to 4-sphingenine (sphingosine) in amide linkage. Ceramides accumulate in people with Farber disease.

ceramide

/cer·a·mide/ (ser´ah-mīd) the basic unit of the sphingolipids; it is sphingosine, or a related base, attached to a long chain fatty acyl group. Ceramides are accumulated abnormally in Farber's disease.
ceramide trihexoside  any of a specific family of glycosphingolipids; due to a deficiency of α-galactosidase A, they accumulate in Fabry's disease.

ceramide

(sîr′ə-mĭd′, sĕr′-)
n.
Any of a group of lipids that are formed by the linking of a fatty acid to sphingosine, are found in cell membranes, and help to regulate the differentiation, proliferation, and death of cells.

ceramide

[ser′əmīd]
the basic unit of the sphingolipids, consisting of sphingosine or a related base attached by means of its amino group to a long-chain fatty acyl group.

cer·a·mide

(ser'ă-mīd)
Generic term for a class of sphingolipid, N-acyl (fatty acid) derivatives of a long chain base or sphingoid such as sphingenine or sphingosine. Ceramides accumulate in people with disseminated lipogranulomatosis.

ceramide

any of a group of naturally occurring sphingolipids in which the NH2 group of sphingosine is acylated with a fatty acyl CoA derivative to form N-acylsphingosine.

ceramide glucoside
the major sphingolipid accumulated in gaucher's disease.
ceramide lactosidosis
a sphingolipidosis in which ceramide lactoside accumulates in neural and visceral tissues owing to a deficiency of a β-galactosidase.
