Corneal glycogen synthesis. I. Evidence for a gluconeogenic pathway in beef cornea

Beef eye anterior chambers were perfused with media containing radiolabeled glycogen precursors. Incorporation of 14C from 1-alanine-U-14C into corneal epithelium glycogen suggested the presence of a gluconeogenic pathway in the eye. Failure to isolate radioactive glucose from 1-alanine-U-14C-containing perfusate after passage through the anterior chamber strongly suggests a corneal site for this pathway.
