A nitrogen-containing compound found in foods as part of lecithin and other phospholipids?
Lecithin (which is a name actually applied to a number of different chemicals) may or may not contain an amine group, such as phosphatidylethanolamine. Phospholipids don't necessarily contain amine groups either. So the question doesn't quite jibe with what's out there.
How many types of lipids are present?
Phospholipids are classified according to alcohol they possess so they are classified into three categories: 1) Glycerophosphatides (Glycerol-alcohol based phospholipids): a) Phosphatidic acid (phosphate) (PA) b) phosphatidylcholine (lecithin) (PC) c) phosphatidylinositol (PI) & d) phosphatidylethanolamine (cephalin) (PE), 2)Phospho-inositides (inositol-alcohol based phospholipids): a) phosphatidylinositol phosphate (PIP) b) phosphatidylinositol bisphosphate (PIP2) & c) phosphatidylinositol triphosphate (PIP3), 3) Phospho-sphingosides (sphingol-alcohol based phospholipids): a) Ceramide phosphorylcholine (Sphingomyelin) (SPH) b) Ceramide phosphorylethanolamine (Sphingomyelin) & c) Ceramide phosphorylglycerol (Cer-PE).
Can you get phosphatidylserine from food sources?
The short answer is : Yes. There are THREE major sources for phosphatidylserine: cow brains and soy lecithin and lamb's kidneys (excellent source). Lamb's kidneys, rich in phosphatidylserine, can improve memory and stress response. A study in the journal Nutritional Neuroscience showed high levels were associated with feeling less stressed and having a better mood. Snip out the white cores and fry in a little butter for three minutes each side. As a supplement, the phosphatidylserine derived from cow brains (BC-PS) is banned in the US due to fears about mad cow disease. While phosphatidylserine occurs in soy lecithin, it does differ in molecular structure from the phosphatidylserine found in cow brains. It is important to note that the studies about human cognitive improvement were done with phosphatidylserine derive from cow brains. Your body actually produces phosphatidylserine. However, theraputic doses for memory improvement are 100 mg two-three times a day. While phosphatidylserine occurs in several foods, it is most prevalent in soybeans. However, to obtain 100 mg of phosphatidylserine, you would need to ingest 3 kg of soybeans. Soybeans contain 1.5-3% lecithin which in turn has 14-18% "other phospholipids" (which would include phosphatidylserine). So, ingesting 100 mg of unrefined lecithin should give you about 10-20 mg (approximately) of "other phospholipids". IF this fraction was ALL phophotidylserine (which it is not), it would take about 2000 mg of unrefined lecithin to meet a therapeutic dosage of phosphatidylserine. Besides soybeans, other foods rich in lecithin include egg yolks and chicken and beef liver. As these are foods that many people avoid due to cholesterol, it is highy unlikely that you can ingest enough phosphatidylserine in your diet to meet therapeutic dosages. Add to that the fact that not all ingested phosphatidylserine is adequately absorbed (particularly as our gut ages), and the difficulty becomes even more complicated. Adding lecithin granules to your diet rather than taking lecithin capsules is probably the easiest (and cheapest) way to up the phophatidylserine in your diet. Lecithin contains many other substances beneficial to your health and, like the B-Vitamins, these substances may help each other be more effective. Be wary of the type of lecithin, however. Bulk Foods, have a lot of good information about foods and nutrients. However, if you are suffering from cognitive decline and absolutely must have a specified amount of phosphatidylserine, the supplements which are STANDARDIZED are your best bet. In this case, however, you should consult a natural healing practitioner that will help you through the maze of the supplement world.
What is the indigestible part of a plants is?
Primarily cellulose, which unlike animal cells, use cellulose for their cell walls instead of phospholipids. Most animals lack the ability to digest cellulose, except for ruminants like cows, which have an enzyme called cellulase to break this down.
Qual o nome do elemento quimico NH3?
The name of this chemical, NH3, is ammonia. It is commonly encountered in foods and fertilizers. It is important to remember that ammonia is not an element but a compound.

How soy lecithin is made?
Lecithin is a combination of phospholipids that naturally occur in soybeans. Lecithin gums are obtained from soy oil after the oil has been extracted from the soybean flakes. Lecithin is removed from the soybean oil using a steam precipitation process. Precipitate is spray dryed to be transformed into Lecithin powder for use as ingredient in dry foods and it has the same applications as the liquid Soya Lecithin
What is lecithin used for?
Lecithin is an emulsifier that allows fat and water to mix. Typically it is added to foods as a thickening agent.
What are lecithin rich foods?
Most unprocessed nuts, unprocessed grains, unprocessed soy, and eggs all contain lecithin. Nutrients, including lecithin, affect the taste of many foods. Most commercial manufacturers improve the taste of foods through processing that removes many of the nutrients, including lecithin. And of course, sunflower seeds contain lecithin. NIH research indicates that, when combined with a hearth healthy diet, lecithin can reduce cholesterol (T.A. Wilson, Soy Lecithin Reduces plasma lipoprotein cholesterol and early artherogenesis in hyper cholesterolemic monkeys and hamsters: beyond linolate, Atheriosclerosis, Sep 1998). No MDR for lecithin has been established by NIH or FDA.
How many kinds of lecithins are there?
There are many kind of lecithins that can be found in foods. An example would be soy lecithin which is the most common type of lecithin.
What are the three types of lipids found in foods?
triglycerides, phospholipids, and sterols
Name 3 classes of lipids found in the body and in foods?
Triglycerides, Phospholipids, and Sterol
Does lecithin reduce cholesterol?
Lecithin is an ingredient found in numerous foods that is believed to be good for people with high cholesterol and multiple sclerosis. Although there is no scientific proof for it's curative abilities, patients with high cholesterol tend to swear by it's ability to bring down their levels.
What organic compound are in foods?
All foods contain organic compounds.
What does soy lecithin do?
There are a number of benefits if one takes Lecithin tablets. It is an essential nutrient that helps with the normal function of liver metabolism, brain and nerve function, and body's cells. Lecithin may also assist in preventing the build up of fats and protect one against cardiovascular disease.
