A saponifiable lipid yog ib feem ntawm ester functional pawg. Lawv tau tsim los ntawm cov saw ntev carboxylic acids txuas nrog cov dej cawv ua haujlwm los ntawm kev sib txuas ester uas tuaj yeem ua rau saponification, yog li lub npe. Cov fatty acids raug tso tawm raws li catalyzed ester hydrolysis.
txhais li cas los ntawm cov lipids uas tsis yog Saponifiable?
Cov lipids uas tsis yog tshuaj tiv thaiv kab mob (tseem hu ua lipids yooj yim) yog lipids uas tsis muaj fatty acids raws li cov khoom siv. Ob chav kawm loj ntawm cov lipids uas tsis yog tshuaj yog cov terpenes thiab cov steroids.
Dab tsi yog qhov txawv ntawm Saponifiable thiab non-Saponifiable lipids?
Saponifiable lipids muaj cov kab ntev carboxylic (ntawm fatty) acids, uas txuas rau ib pawg neeg ua haujlwm dej cawv los ntawm ib qho ester linkage Cov fatty acids no tau tso tawm raws li catalyzed ester hydrolysis. Cov chav kawm nonsaponifiable muaj xws li "fat-soluble" vitamins (A, E) thiab cholesterol.
Vim li cas cov roj cholesterol hu ua cov rog uas tsis yog Saponifiable?
Lipids, xws li cov roj (cholesterol), tsis soluble hauv dej thiab yog li tsis tuaj yeem thauj mus rau hauv cov ntshav (ib qho nruab nrab aqueous) tshwj tsis yog lawv complex nrog cov proteins uas soluble hauv dej. Kev sib sau ua ke hu ua lipoproteins.
Cov khoom siv Saponifiable yog dab tsi?
Saponification yog txheej txheem uas suav nrog hloov pauv roj, roj, lossis lipid, rau hauv xab npum thiab cawv los ntawm kev ua ntawmaqueous alkali (xws li NaOH). Soaps yog ntsev ntawm fatty acids, uas nyob rau hauv lem yog carboxylic acids nrog ntev carbon chains. Ib qho tshuaj ntxuav tes yog sodium oleate.

Puas yog cov khoom muaj nqis uas tsis yog cov cuab tam tam sim no?
Ib qho khoom muaj nqis uas tsis yog tam sim no tuaj yeem yog txhua yam lossis tsis muaj nqis. Cov cuab yeej cuab tam uas tsis yog tam sim no yog ib yam khoom muaj nqis xws li av, khoom siv, tshuab, rooj tog, lossis vaj tsev, uas yog siv los tsim cov khoom zoo lossis kev pabcuam .
Lo lus uas tsis tau txhais lus Askiv txhais li cas?

Puas yog cov kab mob uas ua cov photosynthesis yog cov neeg siv khoom?
Nroj tsuag, algae, thiab ib pawg kab mob hu ua cyanobacteria yog tib yam kab mob uas muaj peev xwm ua tau photosynthesis (Daim duab 1). Vim tias lawv siv lub teeb los tsim lawv tus kheej cov zaub mov, lawv hu ua photoautotrophs (lus, "
Yuav ua li cas cov yas siv los ua cov khoom noj uas tsis yog lo thiab vim li cas?
Teflon (Polytetrafluoroethylene) -Teflon yog tsim los ntawm cua sov tetrafluoroethene nrog cov dawb radical los yog ib qho sulphate catalyst ntawm kev kub ntxhov. Kev siv Teflon-Teflon yog siv los ua cov khoom siv uas tsis yog-stick txheej coated thiab ua cov roj foob thiab gaskets.
Dab tsi ntawm cov hauv qab no yog cov kab mob uas tsis yog cellular?
Kab mob, virions, thiab viroidsyog tag nrho cov piv txwv ntawm lub neej tsis yog cellular. Cov kab mob yog cov kab mob uas kis tau cov nroj tsuag, tsiaj txhu, fungi, thiab kab mob. Lawv muaj cov khoom siv caj ces thiab lub tsho tiv thaiv protein.
