Repeated administration of carboxymethylchitin and chondroitinsulfate to rats in doses of 20 and 120 mg/kg/24 hours led to reduction (by 40-55%) of the rate of aldosterone and 18-oxycorticosterone biosynthesis by the rat adrenal glands in vitro. Carboxymethylcellulose, algin and hyaluronic acid displayed no inhibitory effect. In case of a single administration of carboxymethylchitin to rats (50 mg/kg) inhibition of the rate of aldosterone and 18-oxycorticosterone biosynthesis was seen 48 hours after the administration of the preparation and lasted four days. No inhibitory effect was induced by the addition of 10 mg/kg of acid polysaccharides into the incubation medium of the adrenal glands.

The innate immune system plays a critical role in the rapid recognition and elimination of pathogens through pattern recognition receptors (PRRs). Among these PRRs are the C-type lectins (CTLs) langerin, mannan-binding lectin (MBL), and surfactant protein D (SP-D), which recognize carbohydrate patterns on pathogens. Each represents proteins from different compartments of the body and employs separate effector mechanisms.

Alginates are abundant linear polysaccharides produced by brown algae and some bacteria. They have multiple biological roles and important medical and commercial uses. Alginates are comprised of D-mannuronic acid (M) and L-guluronic acid (G) and the ratios and distribution patterns of M and G profoundly impact their physiological and rheological properties.

This study reports on the nutritional quality of protein-polysaccharide extracts obtained from the green seaweed Ulva lacinulata, through a previously optimized method, evaluating the impact of their distinct composition and structure. Protein solubility was strongly influenced by protein-polysaccharide interactions, being higher in extracts with lower polysaccharide content. This, in turn, had a significant impact on the in vitro protein digestibility.
