L-Histidine (CAS 71-00-1) is an essential amino acid that, while not synthesized by humans, is metabolically crucial for numerous biological functions. Its journey from synthesis in microorganisms to its pivotal roles in human metabolism is a complex and fascinating one. As a leading manufacturer and supplier of high-quality amino acids, we provide L-Histidine for various research and industrial applications.

The biosynthesis of L-Histidine is a well-studied pathway in microorganisms like E. coli, starting from phosphoribosyl pyrophosphate (PRPP) and ATP. This intricate process involves multiple enzymatic steps, highlighting the complexity of essential nutrient production in nature. While humans cannot synthesize L-Histidine de novo, they rely on dietary sources to obtain this vital amino acid.

Once obtained, L-Histidine enters several key metabolic pathways. Its most well-known transformation is its decarboxylation by the enzyme histidine decarboxylase to produce histamine. Histamine is a potent biogenic amine that acts as a neurotransmitter, mediates allergic and inflammatory responses, and plays a role in gastric acid secretion. This pathway underscores L-Histidine's importance in physiological regulation and immune function.

Furthermore, L-Histidine can be degraded into intermediates that enter the citric acid cycle, such as alpha-ketoglutarate. This metabolic flexibility allows it to contribute to energy production. It also serves as a precursor for other important compounds like urocanic acid and carnosine, the latter being an antioxidant dipeptide found in muscle tissue. The body also utilizes L-Histidine in protein synthesis and for the maintenance of nerve cell myelin sheaths.

For researchers and industries working with metabolic studies, biochemical assays, or developing health-related products, access to pure L-Histidine is vital.
