CONT

Glycosphingolipids refer to a broad subclass of sphingolipids where carbohydrate moieties(glucose as glucocerebroside or glucosylceramide, galactose as galactocerebroside or galactosylceramide, lactose as lactosylceramide), singly or multiply, are enzymatically linked to the ceramide backbone...

CONT

En fonction de la nature de leur tête polaire, le groupe des SPL [sphingolipides] se divise en deux sous-groupes : les glycosphingolipides et les sphingophospholipides. Les glycosphingolipides ont pour tête polaire un groupement glucidique.

Record 2 2024-09-20

English

Subject field(s)
  • Human Diseases - Various
  • Liver and Biliary Ducts
  • Genetics
CONT

Galactosemia is a rare hereditary disease that can lead to cirrhosis in infants, and early, devastating illness if not diagnosed quickly. This disease is caused by elevated levels of galactose(a sugar in milk) in the blood resulting from a deficiency of the liver enzyme required for its metabolism(breakdown).

OBS

The term "galactosemia" refers to disorders of galactose metabolism that include classic galactosemia, clinical variant galactosemia, and biochemical variant galactosemia...

Record 3 2014-11-18

Record 4 2012-05-10

English

Subject field(s)
  • Genetics
DEF

[Prophage] that has undergone a deletion of its genome.

CONT

The conclusion is that incorporation of the bacterial galactose region into the phage chromosome results in a defective phage which is able to lysogenize recipient bacteria but not to yield progeny particles on induction.

OBS

A region of the bacterial chromosome has been inserted into the prophage genome in substitution for the missing region.

OBS

Also said incorrectly: defective prophage. A defective lysogenic bacterium is a bacterium containing a defective phage.

French

Domaine(s)
  • Génétique
DEF

Prophage qui a perdu une partie de son génome en intégrant un morceau de chromonème bactérien.

CONT

Subject field(s)
  • Food Additives

DEF

... a relatively new polysaccharide gum with great potential. It is a complex, highly branched polymer of arabinose(1 part) and galactose(6 parts), found in the aqueous extract of the Western Larch tree, which is used for lumber production. The commercial source is Larix occidentalis, although other Larix species contain the polysaccharide.

CONT

Except for gum arabic, larch gum is the most readily water-dispersible, polysaccharide gum known. Concentrations of over 40% may be prepared. It, therefore, has the potential of substituting for gum arabic.

French

OBS

[...] employé comme substitut de la gomme arabique pour bonbons, gelées et gomme à mâcher.

OBS

La source française ne précise pas le genre du terme «arabinogalactane», mais on peut déduire qu'il est masculin du fait que ses deux composants (arabinose et galactane) sont masculins.

OBS
