Ponasterone A is a 2beta-hydroxy steroid, a 3beta-hydroxy steroid, a 14alpha-hydroxy steroid, a 20-hydroxy steroid, a 22-hydroxy steroid, a 6-oxo steroid and a phytoecdysteroid. Ponasterone A is a natural product found in Zoanthus, Lomaridium contiguum, and other organisms with data available. D006730 - Hormones, Hormone Substitutes, and Hormone Antagonists > D006728 - Hormones Ponasterone A (25-Deoxyecdysterone), an ecdysteroid, has strong affinity for the ecdysone receptor. Ponasterone A is a potent regulator of gene expression in cells and transgenic animals, enabling reporter genes to be turned on and off rapidly[1][2].

   

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

C11H19NO10 (325.1009)


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
