Product Informations
L-histidine is an essential amino acid that serves as a building block for proteins and plays important roles in various biochemical processes in the body.
Essential Amino Acid: L-histidine is considered an essential amino acid, which means it cannot be synthesized by the body and must be obtained through the diet. It is particularly important during periods of growth and development.
Protein Building Block: L-histidine is incorporated into proteins during protein synthesis. It is one of the 20 standard amino acids that are used to form the primary structure of proteins.
Precursor to Histamine: L-histidine is a precursor for the synthesis of histamine, a biogenic amine involved in various physiological processes. Histamine acts as a neurotransmitter, regulating immune responses, gastric acid secretion, and allergic reactions.
Buffering Capacity: L-histidine has a buffering capacity, meaning it can help maintain the pH balance in bodily fluids. It can act as a weak acid or base, helping to stabilize the pH within a specific range.
Metal Binding: L-histidine can bind to metal ions, such as zinc and copper, and form complexes. These metal-histidine complexes play important roles in enzyme catalysis and other biological processes.
Dietary Sources: L-histidine can be obtained from various dietary sources,including meat, poultry, fish, dairy products, eggs, legumes, whole grains, and certain fruits and vegetables. These foods provide the necessary L-histidine for protein synthesis and other physiological functions.
Health Implications: L-histidine is important for normal growth and development, as well as for the proper functioning of various systems in the body. It is involved in the maintenance of healthy skin, the production of red and white blood cells, and the regulation of gastric acid secretion. L-histidine supplements are sometimes used in certain health conditions, but their use should be done under the guidance of a healthcare professional.
