glycoconjugates

glycoconjugates

1. peptidoglycans

   • functions
     • works as a barrier
       • into bacterias
         • conform one of three possible barriers to the enviroment
   • made by
     • glycosaminoglycans
       • big structure compose of carbohydrates
         • have ionic potencial
           • will attract Na and sodium
             • will keep water molecules
     • core protein
       • big structure which works as a anchorage point
         • medium point of the structure
           • binds to the larger ialuronic acid and stabilizes the glycosaminoglycans
     • ialuronic acid
       • bigger structure where the core proteins will bind
         • its resistent and stable
           • works as a main structure
             • associate to collagen to create to be a structural resistence
   • found
     • periplasmatic space of the bacteria
   • use
     • amino acids
       • aspargine
       • serin
     • carbohydrates
       • acetylgalactosamine
       • xylose
       • galactose

2. glycoproteins

   • functions
     • celullar recognition
       • like
         • inmunoglubilins
           • proteins bind to carbohydrates use as receptors
         • glycocalyx
           • outer layer with its proper carbohydrates patron
   • made by
     • N-acetyl muramic
     • n-acetyl glucosamine
   • found
     • in the membrane of the cells

3. proteoglycans

   • functions
     • matrix hidration
       • have ionic potentials
         • binds many water molecules
     • structural support
       • works with collagen
         • hold the compressions
     • filter of big molecules
       • works as a gel
         • stop the advance of some molecules
           • protect the membrane of the cells
   • made by
     • globular protein
       • protein that actually can use the carbohydrates for its own recognition
     • oligosaccharide
       • group of cyclical carbohydrates
         • bind by
           • O-glucosidic link
           • N-glucosidic link
   • found
     • amorphous substance of the intercellular space
   • use
     • carbohydrates
       • galactose
       • glucose
       • siatic acid
     • amino acids
       • asparagine
       • serin
       • treonin
