Galactosemia

Galactosemia (British galactosaemia, from Greek γαλακτόζη + αίμα, meaning galactose + blood, accumulation of galactose in blood) is a rare genetic metabolic disorder that affects an individual's ability to metabolize the sugar galactose properly. Galactosemia follows an autosomal recessive mode of inheritance that confers a deficiency in an enzyme responsible for adequate ...

Electrical conductivity and dielectric analysis of NaH2PO4 ...

Mar 07, 2018 · The sodium dihydrogen phosphate NaH2PO4 can be obtained by slow evaporation at room temperature and characterized by Xray powder diffraction, scanning electron microscopy (SEM), and electrical impedance spectroscopy.
