β-Alanine

[5] Sources for β-alanine includes pyrimidine catabolism of cytosine and uracil.

[18] β-alanine is converted within muscle cells into carnosine, which acts as a buffer for the lactic acid produced during high-intensity exercises, and helps delay the onset of neuromuscular fatigue.

[15][19] Ingestion of β-alanine can cause paraesthesia, reported as a tingling sensation, in a dose-dependent fashion.

[13][14] Furthermore, many studies have failed to test for the purity of the supplements used and check for the presence of banned substances.

[15] β-Alanine can undergo a transamination reaction with pyruvate to form malonate-semialdehyde and L-alanine.

NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oil Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
