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.

Iduronic acid
Iduronic acid is a constituent of glycosaminoglycans heparin and heparan sulfate in varying proportions providing considerable diversity in sequence and biological function. The glycosaminoglycans (GAGs) are linear polysaccharides with alternating uronic acids (Iduronic acid and Glucuronic acid) and hexosamine residues, in which a limited set of monosaccharide units gives rise to a number of complex sequences by variable substitution with O-sulfate, N-sulfate, and N-acetyl groups. GAGs usually exist as the O-linked side-chains of proteoglycans, displaying a set of physiological functions which is remarkably wide and as yet incompletely explored. They may act as structural components of connective tissue and the extracellular matrix, or as specific ligands in the relationship between the cell surface and its surroundings. Heparan sulfate exists on the surface of most or all mammalian cells and can display a remarkable range of different sequence motifs; its range of interactions and possible functions reflect its structural complexity. The main repeat unit of heparin structurally resembles the protein binding sequences in heparan sulfate, but contains a higher percentage of sulfated residues. Utilized therapeutically as an anticoagulant and readily available in good quantities heparin serves as a useful model for heparan sulfate. Theoretical and experimental studies indicate that L-Iduronic acid residues of glycosaminoglycans are in equilibrium of different conformations, the relative proportion of conformers being a function of sulfation pattern and sequence. This unique conformational flexibility may provide an explanation for the stronger binding and associated higher biological activities of Iduronic acid-containing glycosaminoglycans (such as heparin, heparan sulfate and dermatan sulfate) as compared with other GAGs having similar charge density but with the more rigid glucuronic acid as the major uronic acid residue. Dermatan sulfates and heparins, which contain L-Iduronic acid in their backbone, show higher low-density lipoprotein (LDL)-affinity than chondroitin sulfates, which contain only D-glucuronic acid. Though confirming a non-specific, predominantly electrostatic interaction between GAGs and LDL, these results indicate modulation of LDL affinity by the polysaccharide backbone. Naturally oversulfated dermatan sulfate (SO3H/COOH ca. 1.2), mainly oversulfated at C-2 of Iduronic acid residues, show comparatively higher anticoagulant activity. (PMID: 3076283, 8466951, 8542607, 11087707).

Pectic acid
Pectic acid is a water insoluble, transparent gelatinous acid existing in ripe fruit and some vegetables. Pectic acid exists in the cell walls of plant tissues, and these substances are ingested from vegetables, fruits, etc. Pectic substances are dealt with as dietary fibers, but other physiological functions are not clear. Pectic acid is degraded in the digestive tract of man and it is considered that digestion is by the action of intestinal bacteria. Pectic acid is mainly degraded to 4,5-unsaturated digalacturonic acid and perhaps to 4,5-unsaturated trigalacturonic acid, by the action of the enzymes from bacteria such as Bacteroides sp. and Clostridium sp. in the human digestive tract. Then, they are used as carbon sources by these pectic-acid-using bacteria. (PMID: 12111144). Present in cell walls of all plant tissues. Up to 30\\% w/w of this polysaccharide can be isolated from orange and lemon rind.

Pectin
Pectin, also known as galacturonate or D-lyxose, is a structural acidic heteropolysaccharide contained in the primary and middle lamella and cell walls of terrestrial plants. Its main component is galacturonic acid, a sugar acid derived from galactose. It was first isolated and described in 1825 by Henri Braconnot. It is produced commercially as a white to light brown powder, mainly extracted from citrus fruits, and is used in food as a gelling agent, particularly in jams and jellies. It is also used in dessert fillings, medicines, sweets, as a stabiliser in fruit juices and milk drinks, and as a source of dietary fibre. In plant biology, pectin consists of a complex set of polysaccharides (see below) that are present in most primary cell walls and are particularly abundant in the non-woody parts of terrestrial plants. Pectin is a major component of the middle lamella, where it helps to bind cells together, but is also found in primary cell walls. Pectin is deposited by exocytosis into the cell wall via vesicles produced in the golgi. Pectin is a natural part of the human diet, but does not contribute significantly to nutrition. The daily intake of pectin from fruits and vegetables can be estimated to be around 5g if approximately 500g of fruits and vegetables are consumed per day. Pectin is a heterosaccharide derived from the cell wall of plants. Pectins vary in their chain lengths, complexity and the order of each of the monosaccharide units. The characteristic structure of pectin is a linear chain of alpha(1-4)linked D-galacturonic acid that forms the pectin-backbone, a homogalacturonan.

Glucuronate
A sugar acid formed by the oxidation of the C-6 carbon of GLUCOSE. In addition to being a key intermediate metabolite of the uronic acid pathway, glucuronic acid also plays a role in the detoxification of certain drugs and toxins by conjugating with them to form GLUCURONIDES. Glucuronic acid, an important derivative of glucose, serves several key biological functions: Detoxification: Glucuronic acid plays a crucial role in the detoxification process within the liver. It conjugates with various toxins, drugs, and bilirubin (a breakdown product of heme) to form water-soluble glucuronides. This conjugation process enhances the elimination of these substances from the body. Glycosaminoglycan Synthesis: It is a precursor for the synthesis of glycosaminoglycans (GAGs), such as hyaluronic acid, chondroitin sulfate, and dermatan sulfate. These GAGs are important components of connective tissues, providing structural support and contributing to tissue hydration and lubrication. Ascorbic Acid (Vitamin C) Synthesis: In some animals, glucuronic acid is involved in the synthesis of ascorbic acid, an essential vitamin. Bile Acid Synthesis: Glucuronic acid is also involved in the synthesis of certain bile acids, which are crucial for the digestion and absorption of dietary fats. Metabolism of Steroids and Xenobiotics: It participates in the metabolism of steroids and various xenobiotics (foreign substances), aiding in their elimination from the body. Cell Signaling: Glucuronic acid-containing compounds, like GAGs, can interact with cell surface receptors and influence cell signaling pathways, impacting processes like cell growth, adhesion, and migration.
