Anserine, also known as beta-alanyl-3-methyl-L-histidine, is a naturally occurring dipeptide found predominantly in the skeletal muscles of birds and some mammals. It plays a crucial role in muscle physiology by acting as an intracellular pH buffer, helping to neutralize lactic acid produced during anaerobic metabolism. Additionally, anserine exhibits antioxidant properties, scavenging reactive oxygen species and chelating metal ions that could catalyze oxidative damage. Research suggests potential therapeutic applications in managing conditions like diabetes, hypertension, and cognitive decline due to its ability to inhibit glycation and improve blood flow. As a component of meat and poultry, it contributes to the nutritional profile of these foods. Its presence is higher in white meat compared to red meat.
