“In livers perfused with H14CO3 for 1 min, glucagon decreased the radioactivities of oxalacetate, malate, citrate, and α-ketoglutarate and increased those of aspartate, P-pyruvate, succinate, and fumarate.”
“The changes induced by glucagon indicated stimulation of aspartate and P-pyruvate formation from oxalacetate and of succinate formation from α-ketoglutarate.”
