L-Histidine

Description:

L-Histidine is an essential amino acid that plays a crucial role in various biological processes. It is classified as a polar, positively charged amino acid due to the presence of an imidazole side chain, which can participate in hydrogen bonding and metal ion coordination. L-Histidine is involved in the synthesis of proteins and is a precursor for histamine, a vital neurotransmitter. It has a pKa value around 6.0, indicating that it can act as both an acid and a base, making it important in buffering systems within biological fluids. This amino acid is also known for its role in enzyme catalysis and is found in hemoglobin, contributing to oxygen transport in the blood. L-Histidine is soluble in water and has a relatively high melting point. It is commonly found in dietary sources such as meat, fish, dairy products, and certain grains, making it essential for human health, particularly in growth and tissue repair.
