Alpha-Tetrasaccharide is a metabolite that accumulates in the urine of glucosidase I deficient patients, a defect due to missense mutations in the glucosidase I gene. (PMID 10788335). A tetrasaccharide is a carbohydrate which gives upon hydrolysis four molecules of the same or different monosaccharides. For example, stachyose upon hydrolysis gives one molecule each of glucose and fructose and two molecules of galactose. The general formula of a tetrasaccharide is typically C24H42O21. (Wikipedia).
