L,L-Diaminopimelate (BioDeep_00000875165)

描述信息

Diaminopimelic acid, also known as ll-2,6-diaminopimelate or ll-2,6-diaminoheptanedioic acid, 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. Thus, diaminopimelic acid is considered to be a fatty acid lipid molecule. Diaminopimelic acid is soluble (in water) and a moderately acidic compound (based on its pKa). Diaminopimelic acid can be found in a number of food items such as quinoa, allium (onion), star anise, and dock, which makes diaminopimelic acid a potential biomarker for the consumption of these food products. Diaminopimelic acid can be found primarily in blood, feces, and urine. Diaminopimelic acid exists in all living species, ranging from bacteria to humans. Diaminopimelic acid is a characteristic of certain cell walls of some bacteria. Diaminopimelic acid is often found in the peptide linkages of NAM-NAG chains that make up the cell wall of gram-negative bacteria. When provided, they exhibit normal growth. When in deficiency, they still grow but with the inability to make new cell wall proteoglycan .
2,6-Diaminoheptanedioic acid is an endogenous metabolite.
