Abstract
WHEN α-amino-acids are heated to 100–170° with heavy water and strong acids or bases, heavy hydrogen (D) is introduced in a stable or practically stable position in the amino-acid molecule1,2. The position into which D is introduced seems to be the C—H linkage at the α-C atom ; and further into the ring of some of the aromatic and the heterocyclio amino-acids.
