Abstract

A NEW amino-acid, N ε-(2-amino-2-carboxyethyl)-lysine, in acid hydrolysates of alkali-treated proteins has been reported1,2. The trivial name lysinoalanine was chosen for this compound, which is probably formed by the addition of an amino group of a lysyl residue at the double bond of a dehydroalanyl residue formed after alkaline decomposition of disulphide bonds. Lysinoalanine has been synthesized by two different methods1,3 in order to confirm its chemical structure.
