Metabolite Identification
Common NameL-Pipecolic acid
DescriptionL-Pipecolic acid, also known as (S)-pipecolate or L-homoproline, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. L-Pipecolic acid exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. L-Pipecolic acid has been linked to several inborn metabolic disorders including peroxisomal biogenesis defect and adrenoleukodystrophy.
