Amino acid metabolism in cystinuria

Amino acid imbalance in cystinuria.

After oral ingestion of a free amino acid mixture by three cystinuric patients, plasma increments of lysine and arginine were lower and those of many other amino acids were significantly higher than those found in control subjects. Similar results were obtained in control subjects after amino acid imbalance had been artificially induced by the omission of cystine, lysine, and arginine from the ...

Amino Acid Metabolism

AB S T R A C T To evaluate the factors regulating gluconeogenesis in pregnancy, plasma amino acid levels were determined during the course of an 84-90 hr fast in physically healthy women studied during wk 16-22 of gestation (before undergoing therapeutic abortion), and in nonpregnant controls. The effect of pregnancy on the glycemic response to exogenous alanine administration during starvation...

Malnutrition and Amino Acid Metabolism

Severe childhood malnutrition embraces a spectrum of clinical presentations and pathologic disorders. Across the entire spectrum, there is clear evidence of major changes in the state of amino acid and whole body protein metabolism, from the skeletal wasting and stunting of marasmus to the varied multisystem changes characterized by the kwashiorkor syndrome. For this reason, amino acid and prot...
