title: Mass spectrometric identification of 2-hydroxy-sebacic acid in the urines of patients with neonatal adrenoleukodystrophy and Zellweger syndrome.
abstract: The urines of children with neonatal adrenoleukodystrophy and Zellweger syndrome contained an excess of unusual even- and odd-numbered dicarboxylic acids with a chain length of from 5 to 15 carbon atoms, as well as 2-hydroxy-compounds, including 2-hydroxy-isocaproate, 2-hydroxy-glutarate and 2-hydroxy-sebacate. The latter product, not previously found in metabolic diseases, appears as an additional useful marker of these peroxisomal disorders.
