Lecithin is a type of fat molecule (phospholipid) found naturally in cell membranes and various foods, including egg yolks, soybeans, and certain grains. It plays a crucial role in maintaining the structure and function of cell membranes, as well as in the metabolism and transport of fats and cholesterol. In dietary supplement form, lecithin is often used to support liver health, lower cholesterol levels, and improve digestion.
Lecithinase is an enzyme that breaks down lecithin, a type of phospholipid that is a primary component of cell membranes. It is particularly abundant in the aphids and other insects, as well as certain bacteria.
