TABLE 1.

Glucose kinetics, gluconeogenesis, and source of plasma triglyceride glycerol Values are the mean ± S.E. Conc., concentration in the plasma; GNG, contribution of gluconeogenesis to glucose Ra; GlyNG, contribution of glyceroneogenesis to plasma triglyceride; glycolysis, contribution of glucose to plasma triglyceride. Suc Sup + Glc Inf, sucrose-supplemented animals infused with glucose during the tracer study.
