Lecithin contains dietary precursors to choline, an essential nutrient, which was formerly classified as a B vitamin (vitamin B 4). [17] [18] Lecithin is a mixture of fats that contains phospholipids, including phosphatidylcholine, and the human body can convert phosphatidylcholine into choline.

The name lecithin was derived from Greek λέκιθος, lekithos 'egg yolk' by Theodore Nicolas Gobley, a French chemist and pharmacist of the mid-19th century, who applied it to the egg yolk phosphatidylcholine that he identified in 1847. Gobley eventually completely described his lecithin from chemical structural point of view, in 1874.
Lecithin can be “extracted, and it can also be created synthetically, but the soy lecithin is coming directly from soybeans. As an additive, soy lecithin is an emulsifier that “helps bind ...
Soybean agglutinins (SBA) also known as soy bean lectins (SBL) are lectins found in soybeans. It is a family of similar legume lectins. As a lectin, it is an antinutrient that chelates minerals. In human foodstuffs, less than half of this lectin is deactivated even with extensive cooking (boiling for 20 minutes). [1]
In general, a lecithin, or more precisely a phosphatidylcholine is obtained using a saturated fatty acid, in the example here palmitic acid or hexadecanoic acid H 3 C-(CH 2) 14-COOH (margaric acid identified by Gobley in egg yolk, now named heptadecanoïc acid H 3 C-(CH 2) 15-COOH, belongs to that class) and an unsaturated fatty acid, here ...

Percy Lavon Julian (April 11, 1899 – April 19, 1975) was an American research chemist and a pioneer in the chemical synthesis of medicinal drugs from plants. [1] Julian was the first person to synthesize the natural product physostigmine, and a pioneer in industrial large-scale chemical synthesis of the human hormones progesterone and testosterone from plant sterols such as stigmasterol and ...
