Title: Contribution of ε-Amino Groups to Ninhydrin Color Production in Proteins
Abstract: The ninhydrin color given by model compounds and by characterized proteins shows a consistent contribution from the ε-amino group of lysine of about 67 percent of that of an α-amino group, except in free lysine or in N-terminal lysine, where the ε-amino group makes a small contribution (7 to 10 percent) to the total color. This information can be applied to structure determination of Nε peptides of lysine.
