UTILIZATION OFL-α-GLYCEROPHOSPHORYLCHOLINE BY A LECITHIN-DEFICIENT STRAIN OF NEUROSPORA CRASSA

Abstract
The growth response of a lecithin-deficient strain of Neurospora crassa to equimolar supplements of either choline or glycerophosphorylcholine is essentially the same. This is in contrast to the negligible stimulatory effect of phos-phorylcholine on growth of the same organism. The results of enzymatic and growth-response studies with Neurospora suggest that glycerophosphorylcholine is available to the organism without prior hydrolysis by enzymes released into the culture medium.
