Chapter 154. Choline | Properties and Determination
Melissa M. Phillips
Choline is an essential nutrient that is required for normal cell function, with involvement in numerous cellular processes. Choline can be produced via de novo biosynthesis, but must be complimented with dietary intake to support optimum health. Foods highest in total choline content include egg yolks, liver (from beef, veal, chicken, turkey), and wheat germ. In order to properly assign levels of choline in foods to establish intakes, as well as in body fluids to evaluate health status, appropriate analytical methods that are both accurate and precise should be used. Classical and current methodologies are discussed.
