Is N acetylneuraminic acid a sugar?
It is a nine-carbon amino sugar formed by the condensation of mannosamine 6-phosphate and phosphoenolpyruvate (PEP). It is the parent substance of the sialic acids which are acyl derivatives of neuraminic acid, e.g. N-acetylneuraminic acid.
What foods contain Neu5Gc?
Dietary sources that are rich in Neu5Gc include red meats such as beef, pork, lamb, and to a much lesser degree, cow’s milk products. Of significant note is the fact that plants and poultry do not contain Neu5Gc, and that fish samples studied so far contain low to trace amounts (58, 60).
Where is Neu5Gc found?
Not produced in humans, Neu5Gc occurs naturally in lamb, pork and beef, the so-called “red meats”. Levels are very low or undetectable in fruits, vegetables, hen’s eggs, poultry and fish.
Is sialic acid good for you?
Sialic Acid can effectively promote the development and functional repair of nerve cells, epithelial cells and immune cells, which can get the effect of improving immunity, promoting intellectual development , nourishing skin and anti-aging.
Is Neuraminic acid an aldose?
The N- or O-substituted derivatives of neuraminic acid are collectively known as sialic acids, the predominant form in mammalian cells being N-acetylneuraminic acid. The amino group bears either an acetyl or a glycolyl group….Neuraminic acid.

Does whey protein contain Neu5Gc?
It can also be found in dairy products, but to a lesser extent. Some 1.1% of the identified Neu5Ac is actually Neu5Gc in commercial whey protein. Neu5Gc cannot be found in poultry and is found in only trace amounts in fish. This confirms that Neu5Gc is mainly found in foods of mammalian origin.
Is Neu5Gc a sugar?
Neu5Gc is a common sialic acid type of sugar in mammals. It is a nine-carbon negatively charged monosaccharide that can be synthesized by most mammals and found at the tips of carbohydrate chains (glycans), glycoproteins, and glycolipids [6].
Does whey protein have Neu5Gc?
Neu5Gc is found in most mammals, with exceptions like humans, ferrets, the platypus, western dog breeds and New World monkeys. Some 1.1% of the identified Neu5Ac is actually Neu5Gc in commercial whey protein. Neu5Gc cannot be found in poultry and is found in only trace amounts in fish.
Does sialic acid provide energy to cells?
Sialic acids are also used as an energy source in bacteria [14] and reports exist that dietary sialic acids play nutritional roles in mammals [15]. The uptake of exogenous sialic acid [8] and its metabolism in mammalian cells (as summarized in Fig.
What is the importance of Neuraminic acid?
Neuraminic acid is an important component of polysaccharide chains in glycoproteins and glycolipids of cell membranes. This nine-carbon compound is formed by the amino-sugar mannosamine and pyruvic acid; generally the N is acylated, forming sialic acids.
