Desmosine

C24H40N5O8+ (526.287674)

Desmosine is formed by condensation of four molecules of lysine into a pyridinium ring. Elastin molecules aggregate in the extracellular space where they are crosslinked by stable desmosine bridges. The resulting polymer is structurally organized as branched fibers and lamellae, which, in skin, are wider (a few microns) in the deep dermis and become progressively thinner (fraction of a micron) towards the papillary dermis. Several general and local factors seem to regulate elastin gene expression, deposition and degradation. (PMID: 9297692). Desmosines are crosslinking amino acids unique to mature elastin in humans. Owing to this unicity, they have been discussed as potentially indicators of connective tissue disorders whose clinical manifestations are mostly the result of elastin degradation. (PMID: 17390614). Emphysema (Pulmonary emphysema is a devastating disease for which there is no effective treatment) is associated with degradation of elastic fibers (PMID: 14704646). It has been shown that the urinary concentration of elastin specific crosslinks, desmosine correlates well with liver fibrosis score in biopsy specimens from patients with liver disease secondary to hepatitis C virus and alcohol.

2-(4-Amino-4-carboxybutyl)-1-(5-amino-5-carboxypentyl)-3,5-bis(3-amino-3-carboxypropyl)pyridinium. A rare amino acid found in elastin, formed by condensation of four molecules of lysine into a pyridinium ring. Degradation production of Elastin which, together with Desmosine BDC57-J, is believed to be responsible for cross-linking the polypeptide chains of Elastin to form insoluble elastic fibres
