Definition of ornithine in English:
An amino acid produced by the body that is important in protein metabolism.
- About 50-percent of ingested arginine is rapidly converted in the body to ornithine, primarily by the enzyme arginase.
- When your body doesn't digest protein completely, gut bacteria convert two of the amino acids in protein, arginine and ornithine, to compounds called polyamines.
- This may occur in part as a result of pathologically elevated activity of arginase, an enzyme that hydrolyzes arginine to ornithine and urea.
