ascorbic acid

Further, connective tissue parameters like hydroxyproline (control 109.8 [+ or -] 2.6 [micro]g/mg protein), hexuronic acid (control 11.4 [+ or -] 0.4 [micro]g/mg protein), and hexosamine (control 135.1 [+ or -] 5.9 [micro]g/mg protein) were significantly increased in AME treated group by 64.4% (P < 0.001), 53.8% (P < 0.001), and 33.7% (P < 0.01), respectively (Figure 4).

The glycosaminoglycans from the chicken comb (~500 g in hexuronic acid) were applied to a Mono-Q column coupled to a FPLC system, equilibrated using 20mM Tris-HCl (pH 8.0) and submitted to a NaCl (0 to 1.5M) linear gradient in the same buffer.

vitamin C, they have my express permission to do so--or hexuronic acid or antiscorbutic vitamin or missing stress hormone......

In essence, glycosaminoglycans are long unbranched chains of repeating disaccharide units, each comprising an N-acetyl hexosamine and either a hexose or hexuronic acid.

In the pulp and paper sector, many authors have already published work showing the relations between alkali charge, cooking temperature, retention time, bleachability, yield, lignin structures, hexuronic acids, and other factors.

Two weeks later, Szent-Gyorgyi reported that his hexuronic acid (see 1928) was vitamin C, and he was right.

The new substance was named hexuronic acid, the research paper was published and Szent-Gyorgyi received his Ph.D.

Szent-Gyorgyi (see 1928, Hexuronic Acid) had found that any four different four-carbon acids, if added to tissue slices, stimulated oxygen uptake.
