N-Glycolylneuraminic acid
N-Glycolylneuraminic acid (Neu5Gc) is a widely expressed sialic acid found in most mammalian cells. Although humans are genetically deficient in producing Neu5Gc, small amounts are present in human cells and biofluids. Humans cannot synthesize Neu5Gc because the human gene CMAH is irreversibly mutated, though it is found in apes. This loss of the CMAH gene was estimated to have occurred two to three million years ago, just before the emergence of the genus Homo. A dietary origin of Neu5Gc was suggested by human volunteer studies. These trace amounts of Neu5Gc were determined to come from the consumption of animals in the human diet (i.e. red meats such as lamb, pork, and beef). Neu5Gc can also be found in dairy products, but to a lesser extent. Neu5Gc is not found in poultry and is found in only trace amounts in fish (Wikipedia). Isolated from beef serum KEIO_ID G062
NeuNGc
NeuNGc, also known as N-Glycolylneuraminic acid or Neu5GC, is classified as a member of the N-acylneuraminic acids. N-acylneuraminic acids are neuraminic acids carrying an N-acyl substituent. NeuNGc is considered to be soluble (in water) and acidic

N-glycoloyl-beta-neuraminic acid
An N-acylneuraminic acid in which the acyl substituent on nitrogen is glycolyl and which has beta-configuration at the anomeric centre.
N-glycoloyl-alpha-neuraminic acid
An N-acylneuraminic acid in which the acyl substituent on nitrogen is glycoloyl and which has alpha-configuration at the anomeric centre.
