D-Glucuronate
Glucuronic acid (CAS: 6556-12-3) is a carboxylic acid that has the structure of a glucose molecule that has had its sixth carbon atom (of six total) oxidized. The salts of glucuronic acid are known as glucuronates. Glucuronic acid is highly soluble in water. In humans, glucuronic acid is often linked to toxic or poisonous substances to allow for subsequent elimination, and to hormones to allow for easier transport. These linkages involve O-glycosidic bonds. The process is known as glucuronidation, and the resulting substances are known as glucuronides (or glucuronosides). Glucuronidation uses UDP-glucuronic acid (glucuronic acid linked via a glycosidic bond to uridine diphosphate) as an intermediate. UDP-glucuronic acid is formed in the liver of all animals. D-Glucuronic acid is an important intermediate isolated from many gums. D-Glucuronic acid and its derivative glucuronolactone are as a liver antidote in the prophylaxis of human health. D-Glucuronic acid has an anti-inflammatory effect for the skin[1]. D-Glucuronic acid is an important intermediate isolated from many gums.

N-Acetyl-b-D-galactosamine
N-acetyl-β-d-galactosamine, also known as 2-acetamido-2-deoxy-beta-D-galactopyranoside or 2-deoxy-2-acetamido-B-D-galactopyranose, is a member of the class of compounds known as N-acyl-alpha-hexosamines. N-acyl-alpha-hexosamines are carbohydrate derivatives containing a hexose moiety in which the oxygen atom is replaced by an n-acyl group. N-acetyl-β-d-galactosamine is soluble (in water) and a very weakly acidic compound (based on its pKa). N-acetyl-β-d-galactosamine can be found in a number of food items such as opium poppy, watercress, lemon verbena, and green bean, which makes N-acetyl-β-d-galactosamine a potential biomarker for the consumption of these food products. N-Acetyl-b-D-galactosamine is an oligosaccharide residue found in the lining and glandular epithelium, the stroma and the vessels (capillary and large vessels of the human postmenopausal endometrium. (PMID: 8930627). It is suspected that N-Acetyl-b-D-galactosamine is a molecule that binds to IgA in the glomerular mesangium in Henoch-Schoenlein purpura associated nephropathy (the most common vasculitis of childhood). (PMID: 10732728).
