1902Med. Rev. V. 94/2 (heading) The clinical importance of chronic pentosuria. 1936Nature 7 Nov. 805/2 There are known to be at least two types of the rare chronic pentosuria, differing in the nature of the pentose sugar found, one being optically inactive dl-arabinose and the other l-xyloketose. 1970Passmore & Robson Compan. Med. Stud. II. xxxi. 9/1 [Garrod] suggested that in alkaptonuria, albinism, cystinuria and pentosuria there was a block in a metabolic process due to an inherited deficiency of a specific enzyme.

1906J. L. Salinger tr. F. Blumenthal in R. C. Cabot Mod. Clin.

Ibid. 271 Have pentosurics..a special liability to become diabetics? 1933Cameron & Gilmour Biochem. of Med. vi. 91 Diabetic treatment is unsuitable to the pentosuric. 1964D. Y. Hsia in G. A. Duncan Dis. Metabolism (ed. 5) v. 349 In the 1950's, Lasker reported that she had identified l-xylulose in all 72 pentosuric urines that she had tested. 1968Marks & Samols in F. Dickens et al. Carbohydrate Metabolism II. xiii. 351 The existence of this pathway of glucose metabolism was first recognised as a result of studies on the biosynthesis of l-ascorbic acid in animals and of l-xylulose in pentosurics. |
