► Fatty acid phospholipid bilayers are exposed to 0–50% D2O in this study. ► D/H on fatty acids is clearly exchanged (e.g., 93–328‰ in 50% D2O) for 12h. ► However, this exchange is considered to be insubstantial in natural environments. ► These results imply that the hydrogen isotope ratio can be us...
