[mann(a) + –ose.]

Examples

  • The stuff. isn't an antibiotic, as the name suggests, but an endotoxin fraction-a complex organic sugar - called a mannose; it got its name from the fact that it's produced by fermentation, as antibiotics are.

    Cities In Flight

  • You can also consume D-mannose, which is a 100\% natural sugar solution that attracts the harmful bacterium towards itself and flushes it out of the urinary tract.

    Best Syndication -

  • Ohio State University researchers have determined that Mycobacterium tuberculosis has learned through evolution to coat itself with a sugar called mannose, which makes the bacterium attractive to cells in the lungs that are looking to clean up and discard unwanted sugar in the body.

  • Glucose converts to sorbitol, mannose to mannitol, and maltose to maltitol.

    Sweeter Than Sugar?

  • Carbohydrate metabolism: positive selection was observed for genes involved in breaking down mannose in Yorubans, sucrose in East Asians, and lactose for Europeans.

    Human Evolution

  • Similarly, East Asians show genetic changes that affect the metabolism of the sugar sucrose, while the Yoruba people in sub-Saharan Africa show genetic changes that alter how they metabolize the sugar mannose.

    Natural Selection In Action

  • In chordates, collectins initiate the lectin cascade through members of the mannose-binding protein (MBP)—associated protease (MASP)/C1r/C1s family.

    The sea urchin genome - The Panda's Thumb

  • Mannans are plant polysaccharides that are polymers of mannose.
