5 Arginine , Citrulline , and Ornithine
Metabolism as well as function of the three amino acids, L-arginine, L-citrulline, and Lornithine, are closely intertwined and related to the homeostasis of nitric oxide at the tissue and cellular levels. For the three compounds data on neural tissue and CSF levels are summarized and localization in brain mainly derived from immunohistochemical experiments is reported. A complex pattern of diff...
متن کاملAllantoic cyst – an unusual umbilical cord swelling
We report a baby with an unusual umbilical cord swelling. On the antenatal scans, a cystic area within the umbilical cord near its insertion onto the abdominal wall was detected. Postnatally an unusually thick umbilical cord with a yellow fluid filled cyst at the base was noted. The fluid from the cyst was confirmed as urine and ultrasound confirmed patent urachus. The baby underwent a cystosco...
متن کاملEnzymatic transamination reactions involving arginine and ornithine.
Recent research has resulted in considerable modification of the earlier concept that enzymatic transamination was limited to reactions between alanine, aspartate, glutamate, and their or-keto analogues. Reactions leading to the reversible amination of the cY-keto analogues of many of the natural amino acids have been described (l-5), and there is also evidence that aldehyde groups may particip...
متن کاملCan arginine and ornithine support gut functions?
Arginine and ornithine are precursors of nitric oxide and polyamines, respectively. These metabolites intimately participate in permeability and adaptive responses of the gut. The liver possesses high arginase activity as an intrinsic part of urea synthesis and would consume most of the portal supply of dietary arginine. The gut reduces this possibility by converting dietary arginine to citrull...
متن کاملBiosynthesis of arginine from canavanine and ornithine in kidney.
Borsook and Dubnoff (1, 2) and Bloch and Schoenheimer (3) have demonstrated that the amidine moiety of arginine is the precursor of the corresponding group of glycocyamine; in mammals this reaction is carried out primarily in the kidney. Fuld (4) has recently observed that the arginine-glycine transamidination reaction is reversible. By means of group transfer the high chemical potential of the...
