Modulating the Gut Microbiota with Alginate Oligosaccharides In Vitro

Nutraceuticals, 2022
Alginate oligosaccharides (AOS) are non-digestible carbohydrates from brown kelp. As such, they are dietary fibers and may have prebiotic potential. Therefore, we investigated the capacity of gut bacteria to utilize AOS with single-strain cultures and as

Antihypertensive Effects of Sodium Alginate Oligosaccharides.

Journal of the agricultural chemical society of Japan, 2001
Two types of alginate oligosaccharides (Na-AO and K-AO) were prepared by cleavage of alginate polysaccharide with alginate lyase. In this study, the effects of these oligosaccharides on blood pressure of spontaneously hypertensive rats (SHRs) were investigated. In the Na-AO experiment, Na-AO and NaCl groups were fed a normal diet (CE-2, Clea Japan Inc.)

Advances in Research on the Bioactivity of Alginate Oligosaccharides. [PDF]

Mar Drugs, 2020
Alginate is a natural polysaccharide present in various marine brown seaweeds. Alginate oligosaccharide (AOS) is a degradation product of alginate, which has received increasing attention due to its low molecular weight and promising biological activity. The wide-ranging biological activity of AOS is closely related to the diversity of their structures.
