Galactans of (Gracilariales, Rhodophyta) of Indian Waters

Natural Product Communications, 2014
Galactans from the Indian agarophyte Gracilaria pudumadamensis were extracted and characterized. The isolated native (GP Native ) and alkali treated (GP Alkali ) galactans were characterized by IR, 13 C NMR, GC-MS and GPC. It was found that GP Native and

Galactanases and Mannanases Improve the Nutritive Value of Maize and Soybean Meal Based Diets for Broiler Chicks

The Journal of Poultry Science, 2006
Maize and soybean meal are the most common ingredients in diets for monogastric animals. Although maize is low in anti-nutritive factors, soybean meal often contains significant levels of soluble galactans, mannans or oligosaccharides of the raffinose ...

Impact of short-term heat treatment on the structure and functional properties of commercial furcellaran compared to commercial carrageenans

Heliyon, 2021
In the production of biopolymers, the processing operations (e.g. extraction and drying) involve some degradation of the polysaccharide-causing structural and functional changes in final products.

Biosynthesis of the Galactan Component of the Mycobacterial Cell Wall [PDF]

Journal of Biological Chemistry, 2000
The structural core of the cell walls of Mycobacterium spp. consists of peptidoglycan bound by a linker unit (-alpha-L-Rhap-(1-->3)-D-GlcNAc-P-) to a galactofuran, which in turn is attached to arabinofuran and mycolic acids. The sequence of reactions leading to the biogenesis of this complex starts with the formation of the linker unit on a polyprenyl ...

Galactan synthesis in a single step via oligomerization of monosaccharides

Beilstein Journal of Organic Chemistry, 2014
Galactans ranging in length from one to five residues were prepared in a single step by treatment of the glycosyl donor 2,3,4-tri-O-benzoyl-β-D-galactopyranosyl fluoride with lanthanum perchlorate in the presence of an initiator alcohol.

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...
