D-Glucuronate

(2S,3S,4S,5R,6S)-3,4,5,6-tetrahydroxyoxane-2-carboxylic acid

C6H10O7 (194.042651)


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.

C6H10O8 (210.03756600000003)


Glucaric acid, also known as glucarate or D-saccharic acid, belongs to the class of organic compounds known as glucuronic acid derivatives. Glucuronic acid derivatives are compounds containing a glucuronic acid moiety (or a derivative), which consists of a glucose moiety with the C6 carbon oxidized to a carboxylic acid. Glucaric acid is a sugar acid derived from D-glucose in which both the aldehydic carbon atom and the carbon atom bearing the primary hydroxyl group are oxidized to carboxylic acid groups. D-glucaric acid is found in fruits, vegetables, and mammals. The highest concentrations of glucaric acid are found in grapefruits, apples, oranges, and cruciferous vegetables (PMID: 18772850). Glucaric acid is produced through the oxidation of glucose. Cytochrome P450 is thought to be responsible for the production of D-glucaric acid in vivo (PMID: 3779687). In mammals, D-glucaric acid and D-glucaro-l,4-lactone are also known end-products of the D-glucuronic acid pathway (PMID: 18772850). Glucaric is available as a dietary supplement in the form of calcium D-glucarate and has been studied for therapeutic purposes including cholesterol reduction and cancer chemotherapy (PMID: 9101079). D-Glucaric acid has a potential use as a building block for a number of polymers, including new nylons and hyperbranched polyesters. D-glucaric acid produced from D-glucose has been successfully utilized to produce a hydroxylated nylon.

Galactaric acid

(2R,3S,4R,5S)-2,3,4,5-Tetrahydroxyhexanedioic acid

C6H10O8 (210.03756600000003)


Galactaric acid, also known as mucic acid or galactarate, belongs to the class of organic compounds known as glucuronic acid derivatives. Glucuronic acid derivatives are compounds containing a glucuronic acid moiety (or a derivative), which consists of a glucose moiety with the C6 carbon oxidized to a carboxylic acid. Technically, galactaric acid is an aldaric acid obtained by oxidation of galactose. Galactaric acid exists as a white crystalline powder, which melts at 210 - 230 oC. It is insoluble in alcohol, and nearly insoluble in cold water (1 g/300 mL) but more soluble in hot water (1 g/60 mL).. Galactaric acid exists in all living organisms, ranging from bacteria to plants to humans. In plants, galactaric acid is commonly produced or utilized as an osmorgulator (PMID: 31505987). Galactaric acid has been detected, but not quantified in, several different foods, such as fruits, vegetables and bovine milk. A recent large-scale dietary study found that galactaric acid can serve as a biomarker for long-term dairy intake and for the consumption of carotenoid-rich vegetables (PMID: 33566801). In food production, galactaric acid can be used to replace tartaric acid in self-rising flour or fizzies. Present in ripe fruits of peach and pear.

Iduronic acid

(2S,3R,4R,5S)-2,3,4,5-tetrahydroxy-6-oxohexanoic acid

C6H10O7 (194.042651)


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). Iduronic acid is a constituent of glycosaminoglycans heparin and heparan sulfate in varying proportions providing considerable diversity in sequence and biological function.

Pectin

(2S,3R,4S,5R,6R)-3,4,5,6-tetrahydroxyoxane-2-carboxylic acid

C6H10O7 (194.042651)


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.
