Qhov Tseem Ceeb Qhov txawv - Glycerol vs Fatty Acids
Cov rog yog khaws cia hauv lub cev li triacylglycerols hauv cov ntaub so ntswg adipose. Triacylglycerols yog qhov zoo ntawm lub zog vim nws ua rau lub zog ntau dua piv rau cov khoom carbohydrate. Tab sis vim nws insolubility, nws tsis yog yooj yim siv los ntawm lub cev. Triacylglycerols yog tsim los ntawm fatty acids thiab glycerol koom nrog ester daim ntawv cog lus. Fatty acids yog ntev hydrocarbon chains nrog ib pawg carboxyl (COOH) ntawm alpha kawg ntawm fatty acid saw. Glycerol yog polyol muaj peb pawg hydroxyl (OH pawg) thiab hu ua trihydroxy qab zib cawv. Qhov sib txawv tseem ceeb ntawm fatty acids thiab glycerol yog cov tshuaj muaj pes tsawg leeg ntawm ob lub tebchaw. Fatty acids muaj cov pab pawg carboxyl kawg thaum glycerol poob rau hauv qeb ntawm cawv muaj peb pawg OH.
YGlycerol yog dab tsi?
Glycerol uas tseem hu ua glycerin lossis glycerine yog cov tshuaj tsis muaj tshuaj lom. Nws yog ib qho polyol uas yog cawv muaj peb pawg hydroxyl. Cov mis ntawm glycerol yog C3H8O3 Glycerol yog qab zib, ntshiab, tsis muaj xim hygroscopic. kua uas yog viscous nyob rau hauv cov xwm. Qhov ceev ntawm glycerol yog 1.261 g / ml. Nws cov ntsiab lus kub yog 290 degrees Celsius, thiab nws melting point yog 17.8 degrees Celsius. Glycerol yog denser dua dej thiab muaj qhov kub thiab txias siab dua li dej.
Glycerol yog ib qho polar molecule. Nws yog soluble heev thiab miscible hauv dej vim muaj OH pawg. Cov pab pawg OH no kuj yog lub luag haujlwm rau kev faib cov khoom hygroscopic rau dej. Yog li glycerol nkag tau dej thiab khaws cia. Yog li ntawd, thaum khaws glycerol tshwj xeeb airtight ntim yuav tsum tau siv.
Lub cev ua tiav nws qhov kev xav tau ntawm glycerol los ntawm kev ua kom lipid tawg uas yog catalyzed los ntawm lipases. Glycerol hauv lub cev yog khaws cia rau hauv daim siab thiab cov ntaub so ntswg adipose qhov twg nws rov qab siv los ua triacylglycerols thaum xav tau. Tsis tas li ntawd, glycerol kuj tseem siv los ua kom cov ntshav plasma osmolality. Los ntawm elevating osmolality, dej ntau yog muab rho tawm los ntawm cov ntaub so ntswg mus rau hauv lub interstitial kua. Glycerol los yog glycerin kuj ua raws li tus neeg sawv cev los tiv thaiv cov dej reabsorption hauv ob lub raum los ntawm cov tubules proximal convoluted. Qhov no ua rau cov ntshav qis dua thiab cov kua dej ntau dua thiab cov tshuaj sodium.
Glycerol kuj tseem siv tau lag luam hauv kev lag luam khoom noj ua zaub mov emulsifier thiab tus neeg sawv cev tsw. Glycerol yog siv rau hauv cov khoom tu tus kheej xws li tshuaj txhuam hniav, da dej gel, naj hoom thiab lwm yam tshuaj pleev thiab cream. Nws kuj yog siv los tsim tshuaj.
Fatty Acids yog dab tsi?
Fatty acids yog cov chains ntev ntawm hydrocarbons thiab muaj carboxyl terminal. Lawv yog nonpolar molecules thiab yog li, insoluble nyob rau hauv dej tab sis soluble nyob rau hauv organic solvents. Fatty acids feem ntau yog cov sib txuas ncaj nraim thiab tej zaum yuav muaj tus lej khib lossis tus lej ntawm carbon atoms. Odd-numbered fatty acids feem ntau pom muaj nyob hauv cov kab mob thiab cov nroj tsuag qis lossis tsiaj. Raws li tus naj npawb ntawm cov pa roj carbon atoms nws cov synthesis thiab kev tawg hauv lub cev sib txawv me ntsis. Tus naj npawb ntawm carbon atoms nyob rau hauv ib tug fatty acid chain ranges ntawm 2 mus rau 80. Tab sis feem ntau fatty acids muaj li ntawm 12 mus rau 24 carbon atoms. Raws li tus naj npawb ntawm carbon atoms thiab qhov ntev ntawm cov chains muaj peb hom fatty acid chains.
Fatty Acid Chains
- Short-chain fatty acids - 2 mus rau 6 carbons
- Nruab nrab - saw fatty acids - 8 mus rau 10 carbons lawv raug hu thiab 12 txog 24 lawv hu ua
- Long-chain fatty acids - 12 txog 24
Daim duab 02: Saturated thiab Unsaturated Fatty Acids
Raws li qhov muaj thiab tsis muaj ob daim ntawv cog lus, cov roj fatty acids tuaj yeem muab faib ua cov roj ntsha tsis txaus thiab tsis muaj roj. Saturated fatty acids tsis yog los ntawm ob daim ntawv cog lus. Unsaturated fatty acids tuaj yeem muaj ob daim ntawv cog lus - Monounsaturated fatty acids lossis ntau dua ib daim ntawv cog lus - Polyunsaturated fatty acids. Polyunsaturated fatty acids kuj tseem hu ua fatty acids tseem ceeb vim lawv ua lub luag haujlwm tseem ceeb thiab yuav tsum tau noj ntawm cov zaub mov. Polyunsaturated fatty acids yog cov roj fatty acids ntev thiab yog li tsis tuaj yeem ua ke hauv lub cev (omega 3 thiab omega 6 fatty acids)
Dab tsi zoo sib xws ntawm Glycerol thiab Fatty Acids?
- Ob leeg yog tsim los ntawm Carbon, Hydrogen, thiab Oxygen.
- Ob lub tebchaw koom nrog cov tshuaj tiv thaiv esterification los tsim triacylglycerols.
- Ob lub tebchaw ua si lub luag haujlwm thiab lub luag haujlwm hauv cov roj metabolism

Summary – Glycerol vs Fatty Acids
Fatty acids thiab glycerol yog cov ntsiab lus tseem ceeb uas tau kawm ntau heev vim tias lawv yog cov precursors ntawm triacylglycerols thiab lwm yam lipid compounds. Qhov sib txawv ntawm fatty acids thiab glycerol yog tias fatty acids yog nonpolar linear hydrocarbon chains whereas glycerol yog polar thiab muaj li ntawm ib tug taag 3 carbons txhua koom los ntawm ib pawg hydroxyl. Ob leeg tau txais esterification los tsim cov roj acylglycerols uas muaj lub luag haujlwm tseem ceeb hauv lub cev ntawm cov kab mob. Tus kheej ob qho tib si muaj nws cov khoom thiab kev siv.
