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.
Phosphatidylcholine is the major component of lecithin. It is also a source for choline in the synthesis of acetylcholine in cholinergic neurons. Phospholipids [ 1 ] are a class of lipids whose molecule has a hydrophilic "head" containing a phosphate group and two hydrophobic "tails" derived from fatty acids , joined by an alcohol residue ...
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.
Phosphocholine is an intermediate in the synthesis of phosphatidylcholine in tissues. Phosphocholine is made in a reaction, catalyzed by choline kinase, that converts ATP and choline into phosphocholine and ADP. Phosphocholine is a molecule found, for example, in lecithin.
The average daily phosphatidylserine intake in a Western diet is estimated to be 130 mg. [17] Phosphatidylserine may be found in meat and fish. Only small amounts are found in dairy products and vegetables, with the exception of white beans and soy lecithin. Phosphatidylserine is found in soy lecithin at about 3% of total phospholipids. [18 ...
Dipalmitoylphosphatidylcholine (DPPC) is a phospholipid (and a lecithin) consisting of two C 16 palmitic acid groups attached to a phosphatidylcholine head-group.. It is the main constituent of pulmonary surfactants, which reduces the work of breathing and prevents alveolar collapse during breathing.
The Food and Drug Administration's new rules on "healthy" food labels are voluntary and are scheduled to take effect at the end of February.
The most common example of a phytosome is Lecithin. [1] Phytosomes are claimed to enhance the absorption of "conventional herbal extracts" or isolated active principles, both topically [2] and orally. [3]
