Background
Two forms of elastin have been found: elastin I is present in the ligamentum nuchae, aorta and skin, and elastin II is available from cartilage.
Elastin is the main component of elastic fibres (elastic fibers) in the rawhide tissue. The peptide chain of elastin contains 713 or more amino acid residues. Unlike collagen and keratin, elastin has an amino acid sequence in which there is no continuous repetitive periodic structure throughout the peptide chain, but there are alternating hydrophobic and hydrophilic skin segments. Desmosine and open-chain desmosine formed from oxidized lysyl are unique cross-linked structures of elastin. These cross-linked structures are combined in more than two pairs. Elastic fibers are found primarily in ligaments and vessel walls. The presence of elastic fibers in combination with collagen fibers imparts elasticity and tensile strength to the tissue.
