Epsilon-Acetyl-L-Lysine
Epsilon-acetyl-L-lysine is a chemically modified lysine where the epsilon-amino group is acetylated, used in biochemical research and peptide synthesis. It remains classified under 2922.41.00 as a derivative of lysine, specifically as a salt or ester thereof. The acetylation does not remove it from the scope of lysine derivatives.
