(a) Rh(I) water-soluble catalyst preparation outside of PHIP polarizer and subsequent catalytic cycle inside the PHIP polarizer leading to 1H polarized 1-13C-phospholactate-d2 (1-13C-PLAC-d2). (b) Molecular addition of parahydrogen and polarization transfer leading to 13C HP 1-13C-phospholactate (1-13C-PLAC).18 (c) Molecular addition of parahydrogen and polarization transfer leading to 13C HP 1-13C-phospholactate-d2 (1-13C-PLAC-d2).
