Alkali Scientific Choline Chloride, 2.5 Kg
Choline Chloride is a quaternary ammonium compound widely used in biochemical, nutritional, and laboratory research applications. It functions as an essential nutrient precursor for the biosynthesis of phosphatidylcholine and acetylcholine, molecules that play important roles in cell membrane structure and neurotransmission. In laboratory settings, choline chloride is often included in culture media and biochemical formulations to support cellular metabolism and growth. Researchers also use it in nutritional and metabolic studies to examine lipid metabolism, methyl group transfer pathways, and cellular signaling processes. Its high solubility and stability make it suitable for experimental protocols in life science laboratories, including biochemical assays and metabolic research.
