| transferase deficiency galactosaemia | An autosomal recessive disorder in which there is a deficiency of galactose-1-phosphate uridylyltransferase (see main entry for galactosaemia). (05 Mar 2000) |
| galactosaemia | <biochemistry> A rare genetic (autosomal recessive) disorder characterised by the inability a defect in the enzyme (galactose 1 phosphate uridyl transferase) that converts galactose 1 phosphate into glucose 1 phosphate is absent. Excess galactose 1 phosphate accumulates in the blood and a variety of problems result. Inheritance: autosomal recessive. Origin: Gr. Haima = blood (27 Sep 1997) |

| aldose 1-epimerase | <enzyme> An enzyme catalyzing the reversible interconversion of alpha-and beta-aldoses (e.g., alpha-and beta-d-glucose); also acts on l-arabinose, d-xylose, d-galactose, maltose, and lactose. Synonym: aldose mutarotase, mutarotase. (05 Mar 2000) |
