N-Acetyl-D-glucosamine
N-Acetyl-D-Glucosamine (N-acetlyglucosamine) is a monosaccharide derivative of glucose. Chemically it is an amide between glucosamine and acetic acid. A single N-acetlyglucosamine moiety linked to serine or threonine residues on nuclear and cytoplasmic proteins -O-GlcNAc, is an ubiquitous post-translational protein modification. O-GlcNAc modified proteins are involved in sensing the nutrient status of the surrounding cellular environment and adjusting the activity of cellular proteins accordingly. O-GlcNAc regulates cellular responses to hormones such as insulin, initiates a protective response to stress, modulates a cells capacity to grow and divide, and regulates gene transcription. In humans, it exists in skin, cartilage and blood vessel as a component of hyaluronic acid, and bone tissue, cornea and aorta as a component of keratan sulfate. (PMID 16237703). Monomer of Chitinand is also in the exopolysaccharide from blue-green alga Cyanospira capsulata (CCD) N-Acetyl-D-Glucosamine (N-Acetyl-2-amino-2-deoxy-D-glucose) is a monosaccharide derivative of glucose.
N-Acetylmannosamine
N-Acetylmannosamine, also known as beta-ManNAcc or β-ManNAc, belongs to the class of organic compounds known as acylaminosugars. These are organic compounds containing a sugar linked to a chain through N-acyl group. Within humans, N-acetylmannosamine participates in a number of enzymatic reactions. In particular, N-acetylmannosamine can be biosynthesized from N-acetyl-D-glucosamine, which is catalyzed by the enzyme N-acylglucosamine 2-epimerase. In addition, N-acetylmannosamine and uridine 5-diphosphate can be biosynthesized from uridine diphosphate-N-acetylglucosamine; which is mediated by the enzyme bifunctional UDP-N-acetyl glucosamine 2-epimerase / N-acetylmannosamine kinase. In humans, N-acetylmannosamine is involved in the metabolic disorder called the salla disease/infantile sialic acid storage disease pathway. In the rate-limiting step of the pathway, UDP-GlcNAc is converted into ManNAc by UDP-GlcNAc 2-epimerase, encoded by the epimerase domain of GNE. Improved sialylation after the addition of ManNAc and other supporting ingredients to the culture medium not only increases manufacturing yield, but also improves therapeutic efficacy by increasing solubility, increasing half-life and reducing immunogenicity by reducing the formation of antibodies to the therapeutic glycoprotein When the GNE epimerase kinase does not function correctly in the human body thereby reducing the available ManNAc, it is reasonable to assume that treatment with ManNAc could assist with improving health benefits. There is no available therapy to treat GNE myopathy. ManNAc is the first committed biological precursor of N-acetylneuraminic acid (Neu5Ac, sialic acid). N-Acetylmannosamine is a monosaccharide involved in a range of metabolic processes. It is an amino sugar/amino acid that consists of neuraminic acids, glycolipids and glycoproteins, and is used for the synthesis of sialic acid.
