The crosslinking in elastin occurs by two polyfunctional amino acids, that is, desmosine and isodesmosine
. They are formed by oxidative deamination of three out of every four lysine side chains.
"The primary composition of this matrix is a natural ratio of complex proteins including glycosaminoglycans, collagen, elastin, desmosine, isodesmosine
and transforming growth factor." For more information: www.biova.com
