Parenteral nutrition of injured patients

Injured patients treated with fructose 1,6-diphosphate (1 millimole of phosphate per kilogram per day) together with parenteral nutrition had a better nitrogen balance than patients treated with isocaloric nutrition and an inorganic source of phosphate. Excretion of 3-methylhystidine was similar while tyrosine and alanine output from the extremities was lower in the group of patients given fructose 1,6-diphosphate. The data indicates that the protein sparing action of fructose 1,6-diphosphate is exerted through an increased protein synthesis.
