  1. OLIGOSAKARIDA Hardoko FAKULTAS PERIKANAN DAN ILMU KELAUTAN UNIVERSITAS BRAWIJAYA

  2. OLIGOSAKARIDA • Adalah karbohidrat yang mempunyai 2-10 rantai monosakarida dan dihubungkan dengan ikatan kovalen glikosida. • Ikatan glikosida terbentuk dari reaksi dehidrasi yang mengakibatkan hilangnya atom hidrogen dari monosakarida yang satu dan gugus hidroksil (-OH) dari monosakarida yang lain. • Bila ikatan glikosida dibentuk dari gugus laktol (atom karbon anomerik) dari kedua monosakarida maka akan menghasilkan gula non-pereduksi, dan bila dari gugus laktol dan gugus alkohol maka akan menghasilkan gula pereduksi • Terdiri dari Disakarida, Trisakarida, tetra, dst

  3. Jenis-jenis disakarida : • Sukrosa /sakarosa : D-glukosa & D-fruktosa • Laktosa : D-glukosa & D-galaktosa • Maltosa : D-glukosa & D-glukosa dg ikt -1,4  bisa didpt dr hidrolisis pati dg -amilase • Selubiosa : D-glukosa & D-glukosa dg ikt -1,4  Tata nama : menggunakan 3 huruf simbolutk monosakarida dengan akkhiran f atau p (utk furanosa dan piranosa) Maltosa Sakarosa

  5. oligosaccharide (from the Greek oligos, a few, and sacchar, sugar) is a saccharide polymer containing a small number (typically two to ten[1]) of component sugars • Fructo-oligosaccharides (FOS), which are found in many vegetables, consist of short chains of fructose molecules. (Inulin has a much higher degree of polymerization than FOS and is a polysaccharide.) Galactooligosaccharides (GOS), which also occur naturally, consist of short chains of galactose molecules. These compounds can be only partially digested by humans.

  6. Mannan Oligosaccharides (MOS) are widely used animal feed to improve gastrointestinal health, energy levels and performance. They are normally obtained from the yeast cell walls of Saccharomyces cerevisiae. • Research at the University of Illinois has demonstrated that Mannan Oligosaccharides differ from other Oligosaccharides in that they are not fermentable and their primary mode of actions include agglutination of type-1 fimbrae pathogens and immunomodulation [2] [edit]Therapeutic effects

  7. Carbohydrates have six major functions within the body: • Providing energy and regulation of blood glucose • Sparing the use of proteins for energy • Breakdown of fatty acids and preventing ketosis • Biological recognition processes • Flavor and Sweeteners • Dietary fiber
