Description | DL-Pipecolic acid, also known as pipecolinate or homoproline, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). DL-Pipecolic acid exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. DL-Pipecolic acid exists in all living species, ranging from bacteria to humans. DL-Pipecolic acid has been found to be associated with several diseases known as malaria, schizophrenia, rhizomelic chondrodysplasia punctata, and perillyl alcohol administration for cancer treatment; also dl-pipecolic acid has been linked to the inborn metabolic disorders including adrenoleukodystrophy. |
