Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa)
A desmosine cross-link is formed from three allysyl side chains plus one unaltered lysyl side chain from the same or neighbouring polypeptides.
It is found in elastin. Desmosine causes a yellow color.
This desmosine is responsible for the rubber properties of elastin.
