A comparison of15N proline and13C leucine for monitoring protein biosynthesis in the skin
The tracers L15N-proline and L(1-13C)-leucine were used to explore the synthesis of skin proteins in vivo in rabbits. They orally received a single dose containing an equimolecular mixture of L(1-13C)-leucine and...
