Metabolite Identification

Common Name

L-Xylulose

Description

L-Xylulose, also known as L-lyxulose or L-threo-pentulose, belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms. L-Xylulose has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make L-xylulose a potential biomarker for the consumption of these foods. L-Xylulose is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. L-Xylulose, with regard to humans, has been found to be associated with the diseases such as leukoencephalopathy; L-xylulose has also been linked to the inborn metabolic disorder ribose-5-phosphate isomerase deficiency. Based on a literature review very few articles have been published on L-Xylulose.

Enzymes

Enzyme Details

1. L-xylulose reductase

General function:: Involved in oxidoreductase activity
Specific function:: Catalyzes the NADPH-dependent reduction of several pentoses, tetroses, trioses, alpha-dicarbonyl compounds and L-xylulose. Participates in the uronate cycle of glucose metabolism. May play a role in the water absorption and cellular osmoregulation in the proximal renal tubules by producing xylitol, an osmolyte, thereby preventing osmolytic stress from occurring in the renal tubules.
Gene Name:: DCXR
Uniprot ID:: Q7Z4W1
Molecular weight:: 25742.665
