After various speed and altitude vectors for spacing; cleared to descend via RIIVR arrival Runway 25L. While [we were] descending in VNAV PATH and encountering wake turbulence from preceding aircraft; decelerated too slowly; thus crossing GRAMM Intersection faster than the 280 KIAS speed restriction on the profile. Feel the temporary focus on minimizing the wake effect distracted from properly slowing for the restriction.
A B757-200 Captain reported he missed a speed restriction on arrival into LAX when he was distracted by a wake turbulence encounter.
