Abnormal (Hydroxy)proline Deuterium Content Redefines Hydrogen Chemical Mass
Analyzing the δ2H values in individual amino acids of proteins extracted from vertebrates, we unexpectedly found in some samples, notably bone collagen from seals, more than twice as much deuterium in proline and hydroxyproline residues than in seawater. This corresponds to at least 4 times higher δ2H than in any...Gharibi, Hassan ; Chernobrovkin, Alexey L ; Eriksson, Gunilla ; Saei, Amir Ata ; Timmons, Zena …
