Target type: biologicalprocess
The chemical reactions and pathways resulting in the breakdown of L-xylitol, a five-carbon sugar alcohol derived from xylose by reduction of the carbonyl group. [GOC:ai]
L-xylose catabolic process is the metabolic pathway by which L-xylose, a five-carbon sugar, is broken down for energy. This process occurs in many organisms, including bacteria, fungi, and some plants. It typically begins with the phosphorylation of L-xylose to L-xylulose-5-phosphate by an enzyme called xylose kinase. L-xylulose-5-phosphate is then isomerized to D-xylulose-5-phosphate by xylulose kinase. D-xylulose-5-phosphate can then enter the pentose phosphate pathway, a central metabolic pathway, where it can be converted to glyceraldehyde-3-phosphate and fructose-6-phosphate. These intermediates can then be used for energy production through glycolysis or be used to synthesize other biomolecules. The catabolic process of L-xylose is crucial for the utilization of xylose as a carbon source and for the production of energy and essential metabolites.'
