1-hexadecanoyl-2-(9-oxononanoyl)-sn-glycero-3-phosphocholine + NADPH + H(+) = 1-hexadecanoyl-2-(9-hydroxynonanoyl)-sn-glycero-3-phosphocholine + NADP(+)
1-hexadecanoyl-2-(9-oxononanoyl)-sn-glycero-3-phosphocholine + nadph + h(+) = 1-hexadecanoyl-2-(9-hydroxynonanoyl)-sn-glycero-3-phosphocholine + nadp(+)
