a sphingosylphosphocholine + H2O = a sphingoid base + phosphocholine + H(+)
a sphingosylphosphocholine + h2o = a sphingoid base + phosphocholine + h(+)
a sphingosylphosphocholine + H2O = a sphingoid base + phosphocholine + H(+)
a sphingosylphosphocholine + h2o = a sphingoid base + phosphocholine + h(+)
