Qhov sib txawv tseem ceeb ntawm isoprenoid thiab steroids yog tias isoprenoids muaj ob lossis ntau chav ntawm hydrocarbons, txhua chav tsev nrog tsib carbon atoms teem rau hauv ib qho qauv tshwj xeeb, whereas steroids muaj plaub lub nplhaib tsim nyob rau hauv ib txoj kev tshwj xeeb.
Isoprenoid yog ib chav kawm ntawm cov organic tebchaw uas muaj ob lossis ntau chav ntawm hydrocarbons uas txhua chav muaj tsib carbon atoms teem rau hauv ib qho qauv tshwj xeeb. Ib qho steroid yog cov organic compound peb tuaj yeem pom hauv cov kab mob lom.
Isoprenoid yog dab tsi?
Isoprenoid yog ib chav kawm ntawm cov organic tebchaw uas muaj ob lossis ntau chav ntawm hydrocarbons uas txhua chav muaj tsib carbon atoms teem rau hauv ib qho qauv tshwj xeeb. Cov tebchaw no ua haujlwm ntau yam hauv cov txheej txheem physiological ntawm cov nroj tsuag thiab tsiaj txhu. Lawv kuj muaj ntau yam kev lag luam siv.
Daim duab 01: Biosynthesis ntawm Isoprenoid
Terpenoids yog cov chav kawm loj tshaj plaws ntawm isoprenoids uas ib txwm tshwm sim hauv cov nroj tsuag. Terpenoids lossis isoprenoids yog ib pawg loj ntawm cov organic tebchaw uas tau los ntawm isoprene. Cov no yog ib txwm tshwm sim cov organic tebchaw uas tshwm sim los ntawm 55-carbon compound, isoprene, thiab terpenes (isoprene polymers). Cov no yog cov qauv multicyclic uas muaj cov pa oxygen ua haujlwm. Feem ntau ntawm cov khoom ntuj paub yog terpenoids. Qee lub sij hawm, cov ntsiab lus terpene thiab terpenoid yog siv sib hloov, tab sis cov no txawv ntawm ib leeg vim tias terpenes yog cov hydrocarbon yooj yooj yim thaum terpenoids yog cov sib xyaw ua ke uas muaj cov pab pawg sib txawv.
Dab tsi yog Steroid?
A steroid yog cov organic compound peb tuaj yeem pom hauv cov kab mob lom. Nws ua raws li cov khoom siv hauv kev hloov pauv cov kua dej ntawm cov cell membrane thiab ua ib qho kev taw qhia molecule hauv cov hlwb. Yog li ntawd, nws yog ib tug bioactive organic compound. Lub steroid molecule muaj ib qho kev teeb tsa tshwj xeeb; muaj plaub lub nplhaib tsim nyob rau hauv ib txoj kev tshwj xeeb.
Muaj ntau yam sib txawv ntawm cov tshuaj steroid hauv cov nroj tsuag, tsiaj txhu, thiab cov fungi. Cov steroids no yog tsim nyob rau hauv lub hlwb. Lub hauv paus ntawm steroid ntau lawm yog sterols lanosterol lossis cycloartenol. Cov tebchaw no tau muab los ntawm kev sib tw ntawm triterpene squalene.
Daim duab 02: Dihydroprogesterone, Ib Hom Steroid
Cov qauv tseem ceeb ntawm cov tshuaj steroid feem ntau muaj 17 carbon atoms uas tau sib koom ua ke hauv plaub lub nplhaib fused. Muaj peb 6-tus tswvcuab cyclohexane rings thiab 5-tus tswvcuab cyclopentane nplhaib.
A steroid txawv ntawm lwm cov steroid raws li cov pab pawg ua haujlwm uas txuas nrog plaub lub nplhaib tseem ceeb. Ntxiv mus, lub xeev oxidation ntawm lub nplhaib qauv tuaj yeem ua rau qhov sib txawv ntawm ob lub steroid compounds. Piv txwv ntawm cov tshuaj steroid feem ntau suav nrog lipid cholesterol, estradiol hormone, testosterone, thiab lwm yam.
Qhov txawv ntawm Isoprenoid thiab Steroid yog dab tsi?
Qhov sib txawv tseem ceeb ntawm isoprenoid thiab steroids yog tias isoprenoids muaj ob lossis ntau chav ntawm hydrocarbons, txhua chav tsev nrog tsib carbon atoms teem rau hauv ib qho qauv tshwj xeeb, whereas steroids muaj plaub lub nplhaib tsim nyob rau hauv ib txoj kev tshwj xeeb.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm isoprenoid thiab steroid hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Isoprenoid vs Steroid
Isoprenoid yog ib chav kawm ntawm cov organic tebchaw uas muaj ob lossis ntau chav ntawm hydrocarbons uas txhua chav muaj tsib carbon atoms teem rau hauv ib qho qauv tshwj xeeb. Ib qho steroid yog cov organic compound peb tuaj yeem pom hauv cov kab mob lom. Qhov sib txawv tseem ceeb ntawm isoprenoid thiab steroids yog tias isoprenoids muaj ob lossis ntau chav ntawm hydrocarbons, txhua chav tsev nrog tsib carbon atoms teem rau hauv ib qho qauv tshwj xeeb, whereas steroids muaj plaub lub nplhaib cov qauv txheej txheem nyob rau hauv ib txoj kev tshwj xeeb.
