AI Product Description
*The following content is generated by AI and is for reference only.
L-Threonine is an essential amino acid with the chemical formula C4H9NO3 and the CAS number 72-19-5. As one of the eight essential amino acids for humans, it cannot be synthesized by the body and must be obtained through diet or supplementation. Structurally, it is a white crystalline powder that is highly soluble in water but insoluble in organic solvents like ethanol and ether. Its molecular weight is approximately 119.12 g/mol, featuring a hydroxyl group on the beta-carbon, which distinguishes it from other standard amino acids.
In the pharmaceutical industry, L-Threonine serves as a critical precursor for the synthesis of various therapeutic agents and is used to treat nutritional deficiencies, particularly in patients recovering from surgery or suffering from chronic illnesses. It plays a vital role in protein synthesis, supporting muscle growth and tissue repair. Furthermore, it contributes to the production of collagen and elastin, essential for maintaining skin elasticity and joint health. In clinical settings, it is often included in intravenous nutrition solutions to prevent metabolic imbalances and support immune function.
The agricultural sector utilizes L-Threonine extensively as a feed additive for livestock, poultry, and aquaculture. Since animals cannot synthesize this amino acid efficiently, its addition to feed formulations optimizes growth rates, improves feed conversion ratios, and enhances meat quality. It is particularly crucial for swine and poultry diets to ensure balanced amino acid profiles, preventing developmental stunting and promoting overall animal welfare. Additionally, in the food and beverage industry, it is used as a flavor enhancer and nutritional supplement in sports drinks, energy bars, and infant formulas to boost protein intake and metabolic efficiency.
Beyond these applications, L-Threonine is investigated for its potential neuroprotective properties and its role in regulating lipid metabolism. Research suggests it may help reduce liver fat accumulation and support cardiovascular health. Due to its high bioavailability and safety profile, it remains a staple ingredient in global nutraceutical markets. Whether formulated into tablets, capsules, or liquid supplements, L-Threonine continues to be a cornerstone in modern nutrition science, bridging the gap between dietary requirements and physiological needs across diverse populations and species.
