Part Descriptions

LP15697-3   Lecithin
Lecithin belongs to a group of yellow-brownish fatty substances occurring in animal and plant tissues, and in egg yolk. It is composed of phosphoric acid, choline, fatty acids, glycerol, glycolipids, triglycerides, and phospholipids (e.g., phosphatidylcholine, phosphatidylethanolamine, and phosphatidylinositol). Lecithin is sometimes used as a synonym for pure phosphatidylcholine, a phospholipid that is the major component of its phosphatide fraction. Lecithin may be isolated either from egg yolk or from soy beans. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

LP15697-3   Lecithin
Lecithin naturally occurs in plants and animals. It is composed of glycerol, two fatty acids, a phosphate group, and choline.Lecithin is found in many foods including egg yolks, liver, peanuts, corn, spinach, whole grains, and soy beans.Lecithin is used commercially as an emulsifier in baking mixes, candy, chewing gum, chocolate, ice cream, macaroni, margarine, whipped toppings, and many more.Lecithin in the body is present in bile and functions to help emulsify dietary fats in the lumen of the small intestine. Bile is produced in the liver and stored and concentrated in the gallbladder.
Lecithin is a the most abundant phospholipid that makes up the majority of cellular membranes. Lecithin mixes with oil and water to form micelles.Micelles are spherical shells of fat surounded by lecithin.The nonpolar tails are oriented inward toward the fat and the polar end of lecithin is oriented outward toward the water.The formation of micelles is a mechanical process known as emulsification which breaks fat into small droplets and makes the droplets water soluble.[books.google.com/books?id=bmIMBAAAQBAJ&pg=PA912&lpg=PA912&dq=lecithin+physiology&source=bl&ots=yIbPL5YMWy&sig=WX7E1RPt3q8G7hIehF9ASo3StM0&hl=en&sa=X&ved=0ahUKEwiYusmvvKDWAhWm0YMKHYt7CsgQ6AEISDAJ#v=onepage&q=lecithin%20physiology&f=false][http://science.jrank.org/pages/3881/Lecithin-Dietary-commercial-sources.html] Source: Regenstrief LOINC
