Mannan

Mannan[1] may refer to a plant polysaccharide that is a linear polymer of the sugar mannose. Plant mannans have β(1-4) linkages. It is a form of storage polysaccharide. Ivory nut is a source of mannan.

For the god of the sea, see Manannan mac Lir. For the Tamil film, see Mannan (film). For the hate crime victim, see Xulhaz Mannan.

Mannan may also refer to a cell wall polysaccharide found in yeasts. This type of mannan has a α(1-6) linked backbone and α(1-2) and α(1-3) linked branches. It is serologically similar to structures found on mammalian glycoproteins. Detection of mannan leads to lysis in the mannan-binding lectin pathway. This mannan is the source of MOS used as prebiotics in animal husbandry and nutritional supplements.

Etymology

From 'manna', produced by several species of tree and shrub e.g. Fraxinus ornus from whose secretions mannitol was originally isolated.

gollark: > on the topic of setting up a proxy server - it's a very standard practice to transcode and buffer media via a server, they have simply reversed the roles here by having server and client on the client, which makes sense as transcoding is very intensive CPU-wise, which means they have distributed that power requirement to the end user's devices instead of having to have servers capable of transcoding millions of videos.Transcoding media locally is not the same as having some sort of locally running *server* to do it.
