Nqe Lus Nug: Txhawm rau kom cov suab thaj kom polymerize rau hauv polysaccharide… cov dej molecule yuav tsum tau muab faib ua H thiab OH ua haujlwm pab pawg cov pa oxygen uas nyob rau hauv lub nplhaib qab zib yuav tsum koom nrog cov ntawv cog lus tshiabuas yog tsim O glycerol yuav tsum tsis muaj ib qho ntawm cov saum toj no.
Yuav ua li cas polysaccharides tsim?
Polysaccharides yog tsim thaum lub cev qhuav dej tshwm sim ntawm ntau tus monosaccharides. Amylose (hauv qab) yog polysaccharide muaj li ntawm 60 thiab 300 qabzib units.
Dab tsi yog cov polymers qab zib?
Qab Zib Polymers
- Amylose yog ib qho kab (helical) molecule thaum amylopectin yog branched (muaj 1-6 txuas ntxiv)
- Amylose nyuaj rau zom thiab soluble tsawg dua, txawm li cas los xij, vim nws siv qhov chaw tsawg dua, yog daim ntawv khaws cia hauv cov nroj tsuag.
Lub ntsiab lus dav dav rau cov polymers ntawm polysaccharides yog dab tsi?
Qee lub npe hu ua glycans, muaj peb hom thiab tseem ceeb ntawm polysaccharide, cellulose, starch thiab glycogen, txhua tus ua los ntawm kev sib koom ua ke ntawm cov piam thaj molecules hauv ntau txoj kev.
Cov piam thaj twg koom nrog hauv kev tsim cov polysaccharide?
A polysaccharide yog ua los ntawm ntau monosaccharides txuas ua ke los ntawm glycosidic daim ntawv cog lus.
