| Common Name | L-trans-5-Hydroxy-2-piperidinecarboxylic acid | 
|---|
| Description | L-trans-5-Hydroxy-2-piperidinecarboxylic acid, also known as 5-hydroxypipecolate, 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). L-trans-5-Hydroxy-2-piperidinecarboxylic acid is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on L-trans-5-Hydroxy-2-piperidinecarboxylic acid. |
