生化/生理作用
Isovalerylglycine is a byproduct of the catabolism of the amino acid leucine. Accumulation of isovalerylglycine occurs in Isovaleric Acidemia (IVA), an autosomal recessive disorder caused by mutations in the isovaleryl-CoA dehydrogenase gene. The deficiency of this enzyme in the metabolism of leucine leads to the accumulation of a series of isovaleryl-CoA metabolites, such as isovalerylglycine (IVG).

A stable isotope dilution method was developed to measure accurately small amounts of isovalerylglycine in amniotic fluid and urine for the prenatal diagnosis of isovaleric acidemia. [4,4,4-D3]Isovalerylglycine was synthesized and used as an internal standard. Samples were extracted, methylated, and

Recent neonatal screening for isovaleric acidemia by tandem mass spectrometry based on dried blood-spot levels of C5-acylcarnitines, including isovalerylcarnitine and its isomer, pivaloylcarnitine, which is derived from pivalate-generating antibiotics, has caused many false-positive results. We have developed a method to

When amino acids were infused at a rate of 4 g/kg/day, an infant with hypoglycemia, metabolic acidemia and chronic regurgitation showed hypersarcosinemia and excreted abnormal amounts of sarcosine, isovalerylglycine, isobutyrylglycine, alpha-methylbutyrylglycine, and beta-hydroxyisovaleric, glutaric, alpha-hydroxyglutaric, methylsuccinic, and alpha-hydroxyisobutyric acids in

To assess the effectiveness of glycine and carnitine therapy on isovaleryl conjugate excretion in isovaleric acidemia (IVA). Urinary isovalerylglycine (IVG) and isovalerylcarnitine (IVC) were measured from 12-hour urine specimens collected overnight from an 8-year-old patient with IVA (who had no

Thyroid hormones, riboflavin, riboflavin cofactors, and organic acids were assessed in girls with anorexia nervosa. The objective was to examine the effect of malnutrition and low thyroid hormone concentrations on erythrocyte and plasma riboflavin metabolism and their relation with urinary
