ceramidase

ceramidase

 [sĕ-ram´ĭ-dās]
an enzyme occurring in most mammalian tissue that catalyzes the reversible acylation (incorporation of an acid radical) and deacylation (loss of an acid radical) in ceramides.

cer·am·i·dase

(ser-am'i-dās),
An enzyme that hydrolyzes ceramides into sphingosine and a fatty acid; acylsphingosine deacylase. A deficiency of this enzyme is associated with disseminated lepogranulomatosis.

ceramidase

/cer·am·i·dase/ (ser-am´ĭ-dās) an enzyme occurring in most mammalian tissue that catalyzes the reversible acylation-deacylation of ceramides.

ceramidase

[səram′idās]
an enzyme of the hydrolase class that catalyzes the cleavage of a ceramide to form sphingosine and a fatty acid anion, a step in the degradation of sphingolipids. See also Farber's disease.

cer·am·i·dase

(sĕr-am'i-dās)
An enzyme that hydrolyzes ceramides into sphingosine and a fatty acid. A deficiency of this enzyme is associated with disseminated lipogranulomatosis.

As for the mechanism involved in the decreased production of sphingosine in atopic dermatitis, analysis of the activities of ceramidases, major sphingosine-producing enzymes, revealed that, whereas the activity of alkaline ceramidase did not differ between patients with atopic dermatitis and healthy controls, the activity of acid ceramidase was significantly reduced in patients with atopic dermatitis and this had obvious relevance to the increased colonization of bacteria in those subjects.
D-galactosyl-sn -glycerol + 2 carboxylates Ceramidase 3.
It is composed of a calcium compound and a ceramidase inhibitor, and exhibits three main actions, which have been demonstrated in vitro to promote the structuring and stabilization of the stratum corneum.
