General description
Mannan is the main component of yeast cell wall polysaccharides broadly present in nature, such as in plants, bacteria, yeasts, and other organisms. It comprises a highly branched complex carbohydrate, an α-1,6 backbone with α-1,2- and α-1,3-attached mannose side chains.
Application
Mannan from Saccharomyces cerevisiae has been used to coat the microtiter wells to quantify the levels of mannose-binding lectin (MBL) using a mannan-binding enzyme-linked immunosorbent assay (ELISA).
Mannan from Saccharomyces cerevisiae has been used in a study to assess nonopsonic uptake of Mycobacterium avium complex by human monocytes and alveolar macrophages. It has also been used in a study to investigate new lectins from bulbs of Croccus sativum.
Biochem/physiol Actions
Mannan exhibits several biological properties, including antiproliferative, antioxidant, and immunomodulatory. It is used as a hardener ingredient and as an emulsion stabilizer. Mannan is also involved in the inhibition of pathogen adherence, regulation of bacterial growth, and enhancement of the immune response.

The uptake of Mycobacterium avium complex (MAC) microorganisms by human peripheral blood monocytes (PBMs) and alveolar macrophages (AMs) is not well understood. We have previously shown, under opsonic conditions, that humoral factors are important in mediating the uptake of MAC
