Tom qab ntawd, dab tsi starches siab hauv amylose?

Plaub chav kawm ntawm pob kws hmoov txhuv nplej siab muaj nyob Common pob kws hmoov txhuv nplej siab muaj 25% amylose, thaum siv pob kws yuav luag tag nrho ua los ntawm amylopectin. Ob leeg tshuav pob kws starches yog amylose siab pob kws starches; ib qho muaj 55% txog 55% amylose, thaum thib ob muaj 70% txog 75%.

Qhov thib ob, hmoov txhuv nplej siab ua los ntawm amylose thiab amylopectin yog dab tsi? Cov hmoov txhuv nplej siab yog sib xyaw ntawm ob lub polymers: amylose thiab amylopectin. Lub ntuj tsim muaj li ntawm 10% -30% amylose thiab 70% -90% amylopectin. Amylose yog linear polysaccharide tsim los ntawm D- qab zib cov koom nrog koom nrog α-1, 4-glycosidic txuas peb pom hauv maltose (ib feem) ntawm daim duab 14.7.

Tsis tas li, amylopectin siv rau dab tsi?

Txhua txoj saw hlau muaj kwv yees li ntawm 30 units qab zib. Ib qho nyiaj glycosidic yog siv rau txuas txhua chav qab zib ua ke. Amylopectin muaj ob hom kev sib txuas glycosidic: alpha 1-4 thiab alpha 1-6. Kev ua haujlwm ntawm amylopectin yog los pab txhawb kev siv hluav taws xob rau cov nroj tsuag.

Amylopectin tawg li cas?

Thawj amylose thiab amylopectin tau hydrolyzed rau hauv cov khoom me me los ntawm kev ua ntawm alpha-amylase, zais los ntawm cov qog ua kua qaub hauv qee hom, thiab los ntawm cov txiav txiav hauv txhua qhov.
