The antioxidant and antimutagenic activity of the yeast cell-wall mannan and mannan conjugates--in particular the mannan of Saccharomyces cerevisiae (M-S.c.) and conjugates of mannan S. cerevisiae with human serum albumin (M-HSA1, M-HSA2) and the microbial enzyme penicillin G acylase (M-PGA)--were evaluated in vitro in the unicellular flagellate ...

Immunostimulatory properties of coffee mannans
Molecular Nutrition & Food Research, 2009AbstractCoffee infusion mannans are acetylated polysaccharides containing single Galp and Araf residues as side chains of a β‐(1 → 4)‐Manp backbone. These mannans are structurally similar to the bioactive acetylated mannans from Aloe vera (AV). In this study, acetylated mannans were obtained from two coffee infusions prepared from light and dark ...

Mannosylphosphate transfer to yeast mannan
Biochimica et Biophysica Acta (BBA) - General Subjects, 1999Mannoproteins located in the outermost layer of yeast cell wall determine the wall's porosity and thereby regulate leakage of proteins from the periplasmic space and entrance of macromolecules from the environment. In several yeasts, including Saccharomyces cerevisiae, the glycan portion of mannoproteins is composed not only of neutral oligosaccharides

Quantification of mannan-binding lectin
Journal of Immunological Methods, 2006Mannan-binding lectin (MBL) is attracting considerable interest due to its role in the immune defense. The high frequency of congenital MBL deficiency makes it feasible to evaluate clinical relevance through epidemiological investigations on fairly limited numbers of patients.

The enzymic synthesis of yeast mannan
Biochemical and Biophysical Research Communications, 1963Abstract When guanosine diphosphate mannose (GDP-mannose) was first isolated from yeast, it was proposed that this compound might be the precursor of mannan ( Cabib and Leloir, 1954 ). Evidence supporting this hypothesis will be outlined in the present communication.

Immunochemistry of Candida Mannans
1991The first description on the serological heterogeneity in C. albicans was published by Hasenclever and Mitchell (1961). These workers revealed that this species could be classified into two serotypes, A and B, as judged from the results of agglutination assay between the cells of large number of C.

An approach to the sequencing of yeast mannan
Biochemical and Biophysical Research Communications, 1975Summary A “nearest neighbor” analysis of the products of partial acetolysis of yeast mannan was carried out in an attempt to learn whether the side chains in the polysaccharide are ordered in a sequence or occur randomly. The results suggest that the arrangement is nonrandom, but they do not give unequivocal support to a single repeating sequence.

: Konjac mannan is a main component of tubers of konjac which is a perennial plant of Araceae. It is a heteropolysaccharide consisting of β-d-glucose (G) and β-d-mannose (M), with a G/M ratio of 1 to 1.6. Konjac mannan contains very small amounts of acetyl groups and the viscosity of its aqueous solution is quite high. Deacetylation occurs with alkali
