Alginic acid sulfated

The hemocompatibility of poly(amido-amine) polyelectrolyte complexes was recently studied by Xi, Zhang and coworkers [499, 500]. The poly(amido-amine) was based on piperazine and methylene bisacrylamide, and the polyelectrolyte complexes were obtained from the reaction of poly(amido-amine) with alginic acid, carboxymethyl cellulose or poly(methacrylic acid). Complexes of polyamido-amine and alginic acid with a 1 2 ratio gave the best hemocompatibility. Finally, the blood compatibility of polyelectrolyte complexes based on anionic and cationic cellulose derivatives were studied by Ito et al. [338], In vivo, good blood compatibility of complexes formed from quaternary hy-droxyethyl cellulose reacted with carboxymethyl cellulose and cellulose sulfate was observed.

In the present study, the polysaccharide alginic acid (AlA) with molecular weight (Mw) of 250 000 was chosen as a polyanion. The strong basic protein protamine sulfate (PtS) with Mw about 5000 was used as a polycation. The calcium carbonate matrices were successively employed as a core material because they dissolve in mild conditions and are non toxic. Our motivation to study this combination was to reach the more biocompatible shell composition. 

The stable hollow microcapsules on the basis of natural polysaccharide alginic acid and protein protamine sulfate are formed via LbL method. The (PtS/AlA)4 microcapsules fabricated are promising for biomedical applications.

Antioxidant. Sulfated polysaccharides not only function as dietary fiber, but they also contribute to the antioxidant activity of seaweeds. It has been demonstrated that they exhibit potential antioxidant activity in vitro and several of them derived from brown seaweeds, such as fucoidan, laminaran, and alginic acid, have been shown as potent antioxidants (Rocha De Souza et ah, 2007 Ruperez et ah, 2002 Wang et ah, 2008, 2010). 

The C=0 stretching frequency of the COOH of un-ionized carboxylic acids (Orr et al., 1952 Stevenson and Levine, 1952 Levine eta/., 1953 and, Orr, 1954) lies at 1736cm", including polysaccharides such as hyaluronic acid, the chondroitin sulfates, alginic acid, and pneumococcal capsular material.
