Age estimation by using aspartic acid racemization from purified elastin of aorta
Age estimation is the one of biological profiles which plays an important role in identification in forensic field. The application of biochemical approach known as aspartic acid racemization in human provides more accuracy and less error of estimated age in age determination. During aging, amino ac...

Age estimation is the one of biological profiles which plays an important role in identification in forensic field. The application of biochemical approach known as aspartic acid racemization in human provides more accuracy and less error of estimated age in age determination. During aging, amino acids within protein transform between D-and L-form (racemization), which results in increasing concentration of D-amino acids. This change of amino acids is related to aging. Aspartic acid has been generally applied in racemization because it has fastest rate of racemization. Racemization of aspartic acid not only takes place in teeth and many kinds of bone, but also can occur in the flexible structure which contain mostly elastin. For example, skin yellow ligament, lung parenchyma, and aorta. Elastin is essential protein which is comprised most composition of several structures and it is major content in the elastic fibers.
