Research in cats has shown that increased fermentation-derived propionic acid and its metabolites can be used as alternative substrates for gluconeogenesis, thus sparing amino acids for other purposes. This amino acid sparing effect could be of particular interest in patients with kidney or liver ...
Serum was analyzed for 30 amino acids using an automated high-performance liquid chromatography amino acid analyzer. RESULTS: Serum tryptophan concentrations were significantly decreased in dogs with PLE (median, 22 nmol/mL; range, 1-80 nmol/mL) compared with apparently healthy control dogs (median...
and higher dietary requirements for many amino acids (e.g., arginine, taurine, cysteine, and tyrosine), and are less sensitive to amino acid imbalances and antagonisms. Throughout adulthood, cats and dogs may lose 34% and 21% of their lean body mass, respectively. Adequate intakes of high-...
This chapter will review plasma membrane receptors for amino acids which are or may be neurotransmitters. Our focus will be on the mammalian brain, with brief consideration of simpler animals and peripheral nervous tissue. Although the number of amino acid transmitters is not known at present, it...

Mean (+/- SEM) total free amino acid loss into the dialysate was 2.7 +/- 0.2 g or 0.12 g/kg of body weight.Hemodialysis is associated with significant alterations in plasma amino acid concentrations and loss of free amino acids into the dialysate. Loss of amino acids into the dialysate,...
Tryptophan also known as β-indolylalanine, is one of the essential amino acids for the human body.L-Tryptophan is an important precursor substance for auxin biosynthesis in plants. Its structure is similar to IAA. It is commonly found in higher plants. It is also the precursor ...
In response to the infusion of a mixture of amino acids (20 g during 60 min), plasma pancreatic polypeptide concentrations decreased in normal dogs. The effect was, however, completely reversed by vagotomy, with a significant pancreatic polypeptide release being observed (p < 0.05). Arginine (...
Amino acids (AAs) are defined as organic compounds containing both amino and acid groups (1). Proteinogenic AAs are AAs that serve as substrates for protein synthesis in animal cells, and occur naturally as L-AAs except for glycine. Free AAs (those AAs that are not constituents of peptides...
Intravenous infusion of amino acids is known to inhibit the stimulated pancreas and it has been suggested that this may act as a feedback mechanism in pancreatic regulation. To investigate this, chronic pancreatic fistula dogs were studied to determine if postprandial levels of hyperaminoacidemia inh...
