Choline is an important component of a number of biological compounds, such as neurotransmitter acetylcholine and phospholipid lecithin (phosphatidyl choline). Choline occurs widely in plant and animal foods. It is often present in the form of lecithin and rarely as the free base. Choline is also found in many processed foods and sold as supplements.In the form of lecithin, it is used as an emulsifying agent and additive in commercial food such as mayonnaise and chocolate products.Average daily intake of choline should be 400-900 mg.Choline is ubiquitously distributed in foods where it is present in free and esterified forms. It is required to make the phospholipids phosphatidylcholine, lysophosphatidychloline, choline plasmalogen and sphingomyelin-essential components of all membranes. It is a precursor for the biosynthesis of the neurotransmitter acetylcholine and is also an important source of labile methyl group.Apart from this Shreenath Chemicals also manufacture Active Pharma Ingredients, Pharmaceutical Raw Materials, Bulk Drug, Nutritional Supplements, Drug Intermediates, Fine Chemicals, Ferric Ammonium Citrate, and Calcium Citrate.
