What is amino acid toxicity?
AA toxicity is defined as that adverse ef- fect from an excess of a particular amino acid which is unique and specific.
Which are non protein amino acids?
1(ii) Nonprotein amino acids. Nonprotein amino acids are amino acids other than the 20 amino acids incorporated in protein (Figure 3). More than 900 nonprotein amino acids have been reported from a wide variety of plants including Leguminosae, Liliaceae, Sapindaceae, Cycadaceae, Compositae, Rubiaceae, and Lecythidaceae …
Which foods contain L-Canavanine?
L-canavanine is a common non-protein amino acid found naturally in alfalfa sprouts, broad beans, jack beans, and a number of other legume foods and animal feed ingredients [1] at up to 2.4% of food dry matter.

Are amino acids safe to take everyday?
Protein supplements containing BCAA may have ‘detrimental effects’ on health and lifespan. New research from the University of Sydney suggests that excessive intake of branched-chain amino acids (BCAAs) in the form of pre-mixed protein powders, shakes and supplements may do more harm to health than good.
What foods contain L-Canavanine?
Is it safe to give L canavanine to rats?
The toxicity of L-canavanine was investigated because of its demonstrated potential as an antitumor drug. This natural product was only slightly toxic to Sprague-Dawley rats following a single sc injection: the LD50 was 5.9 +/- 1 8 g/kg in adult rats and 5.0 +/- 1.0 g/kg in 10-day-old rats.
What is the effect of canavanine on peristalsis?
The effect of canavanine is to inhibit the nitric oxide pathway and thereby affect peristalsis. Canaline is a structural analog of citrulline and hence affects the ornithine cycle. Canaline is also toxic due to its ability to react with aldehydes (vitamin B 6) to form oximes and with keto acids.
How is canavanine similar to arginine and canaline?
The toxicity of canavanine is due to the structural similarity of arginine. The effect of canavanine is to inhibit the nitric oxide pathway and thereby affect peristalsis. Canaline is a structural analog of citrulline and hence affects the ornithine cycle.
Where does the amino acid L canavanine come from?
L-Canavanine’s production and use in biochemical research may result in its release to the environment through various waste streams. L-Canavanine is a basic amino acid which occurs naturally in some species of beans and alfalfa.
