SUMMARY (2‐ 14 C)‐MVA (mevalonic acid) is metabolized to two major products by sonicated preparations of purified intact etioplasts isolated from wheat leaves. These metabolites have been identified by their R F values and from the products of their hydrolysis as MVAP and MVAPP (mevalonate‐5‐phosphate and mevalonate‐5‐pyrophosphate, respectively). Intact preparations of etioplasts are essentially impermeable to (2‐ 14 C)‐MVA, even after a red light irradiation.
