Qhov sib txawv tseem ceeb ntawm palmitic acid thiab palmitoleic acid yog tias palmitic acid tuaj yeem ua rau qib HDL cholesterol siab dua, whereas palmitoleic acid ua rau qis qis ntawm HDL cholesterol.
Palmitic acid yog hom saturated fatty acid uas muaj cov tshuaj formula C16H32O2. Palmitoleic acid yog ib hom omega-7-monounsaturated fatty acid uas muaj cov tshuaj formula CH3(CH2)5CH=CH(CH2)7COOH.
Palmitic Acid yog dab tsi?
Palmitic acid yog hom saturated fatty acid uas muaj cov tshuaj formula C16H32O2 Nws tseem hu ua hexadecanoic acid. Nws yog cov saturated fatty acid ntau tshaj plaws uas tshwm sim hauv cov tsiaj, nroj tsuag, thiab kab mob. Cov tshuaj no feem ntau tshwm sim raws li ib feem ntawm cov roj coj los ntawm cov txiv hmab txiv ntoo ntawm cov txiv ntoo roj, uas ua rau li 44% ntawm tag nrho cov rog. Ntxiv mus, cov khoom noj xws li nqaij, cheese, butter, thiab lwm yam khoom noj siv mis kuj muaj palmitic acid, nyob ib ncig ntawm 50-60% ntawm tag nrho cov rog. Tsis tas li ntawd, palmitates tuaj yeem piav qhia raws li cov ntsev thiab esters ntawm palmitic acid.
Daim duab 01: Cov Qauv Tshuaj ntawm Palmic Acid
Cov molar loj ntawm palmitic acid yog 256.43 g / mol. Cov tshuaj no tshwm sim li dawb crystals. Palmitate anion tuaj yeem piav qhia raws li daim ntawv pom ntawm palmitic acid ntawm pH 7.4, uas yog qib physiological pH.
Thaum xav txog cov ntawv thov ntawm palmitic acid, nws yog ib qho tseem ceeb ua tus neeg sawv cev surfactant los tsim xab npum, tshuaj pleev ib ce, muaj pwm tso tawm cov neeg ua haujlwm, thiab lwm yam. Daim ntawv ntawm palmitic acid siv hauv cov ntawv thov no yog sodium palmitate. Sodium palmitate tuaj yeem tau txais los ntawm saponification ntawm xibtes roj. Tsis tas li ntawd, nws qhov xwm txheej pheej yig ua rau nws yog qhov kev xaiv zoo rau kev lag luam khoom noj kom ntxiv kev ntxhib los mos thiab lub qhov ncauj rau cov zaub mov tiav.
Palmitoleic Acid yog dab tsi?
Palmitoleic acid yog hom omega-7-monounsaturated fatty acid uas muaj cov tshuaj formula CH3(CH2) 5CH=CH(CH2)7COOH. Cov molar mass ntawm no compound yog 254.41 g / mol. Cov tshuaj no yog ib feem ntawm glycerides hauv tib neeg cov ntaub so ntswg adipose. Peb tuaj yeem pom nws hauv txhua cov ntaub so ntswg; Txawm li cas los xij, feem ntau nws tuaj yeem pom nyob rau hauv daim siab hauv siab concentrations. Ntxiv mus, peb tuaj yeem tsim cov tshuaj no los ntawm palmitic acid siv stearoyl-CoA desaturase-1.
Daim duab 02: Cov qauv tshuaj ntawm Palmitoleic Acid
Raws li qee qhov kev tshawb fawb tsiaj thiab cell kab lis kev cai, palmitoleic acid tuaj yeem ua cov tshuaj tiv thaiv kab mob thiab txhim kho insulin rhiab heev hauv daim siab thiab cov leeg pob txha.
Thaum xav txog cov khoom noj khoom haus ntawm palmitoleic acid, nws tuaj yeem pom muaj nyob rau hauv cov mis nyuj, tsiaj rog, zaub roj, thiab roj marine. Muaj peev xwm muaj qee qhov chaw botanical ntawm no compounds nrog siab concentration, xws li ntawm 19-29%.
Qhov txawv ntawm Palmic Acid thiab Palmitoleic Acid yog dab tsi?
Palmitic acid thiab palmitoleic acid yog cov organic tshuaj sib txuas. Qhov sib txawv tseem ceeb ntawm palmitic acid thiab palmitoleic acid yog tias palmitic acid tuaj yeem ua rau qib siab ntawm HDL cholesterol, thaum palmitoleic acid ua rau muaj kev sib piv qis ntawm HDL cholesterol.
Cov hauv qab no qhia txog qhov sib txawv ntawm palmitic acid thiab palmitoleic acid hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Palmitic Acid vs Palmitoleic Acid
Palmitic acid yog ib hom saturated fatty acid uas muaj cov tshuaj formula C16H32O2, thaum palmitoleic acid yog ib hom omega-7-monounsaturated fatty acid uas muaj cov tshuaj formula CH3(CH2) 5CH=CH(CH2)7COOH. Qhov sib txawv tseem ceeb ntawm palmitic acid thiab palmitoleic acid yog tias palmitic acid tuaj yeem ua rau qib siab ntawm HDL cholesterol, thaum palmitoleic acid ua rau cov qib qis HDL cholesterol..
