Rubber
RubberHmoov yog ntuj dej-soluble polysaccharide, fermented los ntawm auveobasidiumRubbers. Nws muaj feem ntawm maltrotriose units tau txuas los ntawm α-1,6-glucosidic bonds. Qhov nruab nrab molecular hnyav yog 2 × 105 da.
Pululan hmoov yuav raug tsim mus rau ntau yam khoom. Nws yog ib zaj duab xis zoo heev-yav dhau los, tsim ib zaj duab xis uas yog muab cua sov sib xyaw nrog cov pa oxygen zoo. Nws tuaj yeem siv dav nyob rau hauv ob qho kev lag luam thiab zaub mov noj, xws li encapsulating tus neeg sawv cev, cov nplaum, thiab cov neeg sawv cev.
Pululan hmoov tau siv los ua cov khoom noj muaj zog rau ntau tshaj 20 xyoo hauv Nyij Pooj. Nws tau feem ntau suav tias yog kev nyab xeeb (gras) hauv Asmeskas rau ntau cov ntau dav ntau ntawm cov ntawv thov.
