PDH deficiency is an X linked disease that shows heterogeneous characteristics in both clinical presentation and biochemical abnormality. The PDH Complex is a multi enzyme complex that plays a vital role as a key regulatory step in the central pathways of energy metabolism in the mitochondria. Inheritance and pathophysiology The most commonly seen form of PyruvateDehydrogenaseComplex Deficiency is caused by mutations in the X linked E1 alpha gene and is approximately equally prevalent in both males and females. However, a greater severity of symptoms tends to affect males more often than heterozygous females. This can be explained by x inactivation , as females carry one normal and one mutant gene. Cells with a normal allele active can metabolize the lactic acid that is released by the PDH deficient cells. They cannot, however, supply ATP to these cells and, therefore, phenotype depends largely on the nature severity of the mutation. ref name PMC1016663 cite journal author G K Brown, L J Otero, M LeGris, and R M Brown title Pyruvatedehydrogenase deficiency journal J Med Genet. volume 31 issue 11 pages 875 879 year 1994 month ... 0006.pdf ref Clinical Presentation PyruvateDehydrogenaseComplex Deficiency is generally present ... out. ref name PMC1016663 Treatment Direct treatment that stimulates the pyruvatedehydrogenasecomplex ... the inhibitory phosphorylation of pyruvatedehydrogenasecomplex and thereby activates any residual functioning complex.

The pyruvate scale measures pungency in onions and garlic with units of Mole unit mol g sub fw sub micromoles per gram fresh weight . ref cite web title Spring 2001 Commercial Vegetable Variety Trials url http www.aaes.auburn.edu comm pubs vegetables spring2001.pdf accessdate 2011 06 21 ref It is named after pyruvic acid , the alpha keto acid co product created in the biochemical pathway that forms the lacrimator, syn Propanethial S oxide . The standard onion has an eight rating, while sweet onions have a two or three rating on the scale. The lower the score or scale the more sweet the onions are rated. Anything less than five is considered a sweet onion. The Vidalia onion variety is considered sweet and must have a score of 5.0 mol g sub fw sub or less. Citation needed date February 2007 The Supasweet onion usually grown in Lincolnshire , England registers 1.5 to 2 on the scale. A standard brown onion is usually in the range of 6 7 out of 10. Soil type, rain, and sunlight affect the pungency in onions and garlic and, therefore, their score on the pyruvate scale.
