Chemical Information
FooDB NameL-glutamate γ-semialdehyde
DescriptionL-glutamic-gamma-semialdehyde, also known as 5-oxo-L-norvaline or glutamic acid gamma-semialdehyde, (L)-isomer, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-glutamic-gamma-semialdehyde is soluble (in water) and a moderately acidic compound (based on its pKa). L-glutamic-gamma-semialdehyde can be found in a number of food items such as rubus (blackberry, raspberry), jackfruit, loganberry, and plains prickly pear, which makes L-glutamic-gamma-semialdehyde a potential biomarker for the consumption of these food products. L-glutamic-gamma-semialdehyde exists in all living species, ranging from bacteria to humans. In humans, L-glutamic-gamma-semialdehyde is involved in the arginine and proline metabolism. L-glutamic-gamma-semialdehyde is also involved in several metabolic disorders, some of which include hyperornithinemia-hyperammonemia-homocitrullinuria [hhh-syndrome], prolidase deficiency (PD), arginine: glycine amidinotransferase deficiency (AGAT deficiency), and ornithine aminotransferase deficiency (OAT deficiency).
