Abstract
Summary
In experiments with young chicks the addition of serine to a diet containing isolated soybean protein caused growth depression with marginal levels of pyridoxine. The growth depression can be overcome by the addition of extra dietary pyridoxine. Serine appeared to be readily converted to glycine and there is a suggestion that the metabolic defect is in the conversion of phosphatidylserine to phosphatidylcholine.
