Qhov sib txawv tseem ceeb ntawm cov carbohydrates thiab cov hmoov txhuv nplej siab yog cov carbohydrates tuaj yeem ua cov tshuaj polymeric lossis tsis yog polymeric, thaum cov hmoov txhuv nplej siab yog cov khoom noj muaj fiber ntau.
Carbohydrates yog biomolecules uas muaj carbon, hydrogen, thiab oxygen atoms nrog 2: 1 piv ntawm hydrogen thiab oxygen atoms. Starch yog ib hom carbohydrate.
YCarbohydrates yog dab tsi?
Carbohydrates yog biomolecules uas muaj carbon, hydrogen, thiab oxygen atoms nrog 2: 1 piv ntawm hydrogen thiab oxygen atoms. Cov mis mos rau cov carbohydrates yog Cm (H2O) n. Txawm li cas los xij, tsis yog txhua yam carbohydrates haum hauv cov tshuaj no, e.g. uronic acid, fucose, thiab tsis yog tag nrho cov tebchaw uas muaj hom tshuaj no yog carbohydrates, piv txwv li. formaldehyde, acetic acid, thiab lwm yam.
lo lus carbohydrate yog ib lub ntsiab lus rau saccharide. Carbohydrates muaj xws li qab zib, starch, thiab cellulose. Peb tuaj yeem faib cov carbohydrates ua plaub pawg xws li monosaccharides, disaccharides, oligosaccharides, thiab polysaccharides. Ntawm cov plaub hom no, monosaccharides thiab disaccharides yog cov carbohydrates tsawg tshaj plaws uas muaj qhov hnyav molecular. Feem ntau, cov tshuaj no hu ua suab thaj.
Muaj ntau qhov khoom noj rau cov carbohydrates, suav nrog cov zaub mov ntuj thiab ua tiav. Piv txwv li, carbohydrates muaj ntau nyob rau hauv hmoov nplej, qhob cij, cereal, qos yaj ywm, qab zib, lactose hauv mis nyuj, zib ntab, jam, biscuits, thiab ntau lwm yam khoom qab zib.
Lub luag haujlwm tseem ceeb ntawm carbohydrates hauv cov kab mob muaj sia muaj xws li polysaccharides siv los ua cov khoom siv hluav taws xob, raws li cov khoom siv, xws li cov khoom hauv coenzymes xws li ATP, hauv fertilization, raws li cov khoom hauv lub cev tiv thaiv kab mob, hauv cov ntshav txhaws, thiab lwm yam.
Tsis tas li ntawd, chemistry carbohydrate yog ib ceg tseem ceeb thiab nyuaj ntawm chemistry. Qee qhov kev cuam tshuam loj hauv cov tshuaj lom neeg uas cov carbohydrates koom nrog suav nrog Amadori rearrangement, carbohydrate digestion, Nef cov tshuaj tiv thaiv, Wohl degradation, cyanohydrin cov tshuaj tiv thaiv, carbohydrate acetalization, thiab lwm yam.
Starch yog dab tsi?
Starch yog ib hom carbohydrate uas poob rau hauv pawg ntawm polysaccharides. Nws tseem muaj npe hu ua amylum. Cov khoom no muaj ntau cov piam thaj uas txuas rau ib leeg los ntawm glycosidic bonds. Cov nroj tsuag ntsuab feem ntau tsim cov khoom siv polymeric carbohydrate rau lub zog cia. Peb tuaj yeem pom tias qhov no yog cov carbohydrates ntau tshaj plaws hauv tib neeg cov zaub mov, thiab muaj ntau cov hmoov txhuv nplej siab hauv cov zaub mov tseem ceeb xws li nplej, qos yaj ywm, pob kws, nplej, thiab qos yaj ywm.
Starch yog cov khoom siv dawb, tsis qab, thiab tsis muaj ntxhiab. Nws zoo nkaus li hmoov. Cov hmoov txhuv nplej siab no yog insoluble hauv dej txias thiab cawv. Muaj ob hom khoom hauv cov hmoov txhuv nplej siab raws li cov kab sib txuas lossis helical amylose thiab branched amylopectin. Tus nqi ntawm amylose thiab amylopectin feem ntau yog nyob ntawm hom nroj tsuag; Txawm li cas los xij, qhov no tuaj yeem muaj li ntawm 20 txog 25% ntawm amylose, thiab cov amylopectin ntau li ntawm 75 txog 80%.
Ntxiv rau kev khaws cia lub zog hauv cov zaub mov, cov hmoov txhuv nplej siab tseem yog ib qho tseem ceeb hauv qee qhov kev siv tsis yog khoom noj, uas suav nrog kev ua ntawv, tsim cov corrugated board adhesives, xws li khaub ncaws hmoov txhuv nplej siab, kev tsim cov bioplastic, kev tsim cov gypsum hauv kev tsim kho, etc.
Qhov txawv ntawm Carbohydrates thiab Starch yog dab tsi?
Carbohydrates yog ib qho tseem ceeb biomolecules. Starch yog ib hom carbohydrate. Qhov sib txawv tseem ceeb ntawm cov carbohydrates thiab cov hmoov txhuv nplej siab yog cov carbohydrates tuaj yeem yog cov khoom sib xyaw polymeric lossis tsis yog-polymeric, thaum cov hmoov txhuv nplej siab yog polymeric carbohydrate.
Cov hauv qab no qhia txog qhov sib txawv ntawm cov carbohydrates thiab cov hmoov txhuv nplej siab hauv daim ntawv qhia rau ib sab ntawm kev sib piv.
Summary – Carbohydrates vs Starch
Carbohydrates yog biomolecules uas muaj carbon, hydrogen, thiab oxygen atoms nrog 2: 1 piv ntawm hydrogen thiab oxygen atoms. Cov hmoov txhuv nplej siab yog ib hom carbohydrate uas tuaj nyob rau hauv pawg ntawm polysaccharides. Qhov sib txawv tseem ceeb ntawm cov carbohydrates thiab cov hmoov txhuv nplej siab yog cov carbohydrates tuaj yeem yog cov khoom sib xyaw polymeric lossis tsis yog-polymeric, thaum cov hmoov txhuv nplej siab yog polymeric carbohydrate.
