Qhov sib txawv tseem ceeb ntawm fibrous thiab globular proteins yog cov proteins uas muaj fiber ntau yog cov proteins ntev zoo li cov protein uas tsis muaj dej, tsis muaj zog acids, thiab cov hauv paus tsis muaj zog thaum cov proteins globular yog cov proteins uas muaj cov duab kheej kheej uas yog soluble hauv dej, acids, thiab bases.
Proteins yog ib qho tseem ceeb macromolecules ntawm cov kab mob nyob. Lawv muaj ib los yog ntau dua polypeptide chains ua los ntawm cov amino acids. Yog li, cov amino acid yog lub luag haujlwm thiab cov qauv ntawm cov proteins. Thaum lub sij hawm synthesis ntawm cov proteins, polypeptide chains quav nrog ib leeg los tsim cov qauv peb-dimensional (3D). Raws li qhov tshwm sim ntawm cov qauv peb-seem, muaj ob hom proteins li globular proteins thiab fibrous proteins. Ob hom proteins no tseem ceeb sib npaug vim lawv ua haujlwm ntau hauv lub cev.
Nyob li cas yog Fibrous Proteins?
Fibrous proteins yog dej-insoluble proteins uas tsim ntau hom qauv xws li txhav, qws-zoo li, ntawv-zoo li thiab lwm yam. Tsis tas li ntawd, lawv yog insoluble nyob rau hauv qaug zog acids thiab bases. Raws li lub npe txhais tau hais tias, feem ntau cov proteins uas muaj fiber ntau tau txuas txuas mus rau cov qauv fibrous.
Daim duab 01: Keratin
Fibrous proteins feem ntau pab txhawb kev ua haujlwm xws li muab lub zog tensile, elasticity, rigidity, thiab cov qauv ua haujlwm xws li tsim cov txheej txheem membrane, scaffold cov qauv hauv cov hlwb, thiab lwm yam. Tsis tas li ntawd, fibrous proteins muaj nyob rau hauv daim tawv nqaij, plaub hau, nuclear. daim nyias nyias, cov qe ntshav liab, thiab lwm yam. Qee qhov piv txwv ntawm fibrous proteins yog F-actin, collagen thiab elastin, desmin, fibroin, thiab keratin.
Cov Proteins Globular yog dab tsi?
Globular proteins yog cov dej-soluble proteins nrog cov duab kheej kheej thiab cov amino acid tsis sib xws. Cov saw hlau polypeptide yog folded rau hauv lawv cov duab, thiab cov duab no yog tshwj xeeb rau txhua hom globular protein. Cov dej solubility ntawm globular proteins ua rau lawv thauj mus los ntawm cov ntshav thiab lwm yam dej hauv lub cev mus rau ntau qhov chaw uas yuav tsum tau ua.
Daim duab 02: Globular Protein
Globular proteins feem ntau pab hauv kev nqa ntau yam tshuaj lom neeg, uas ua rau cov kab mob hloov mus rau sab nraud lub zog rau daim ntawv siv hluav taws xob. Cov proteins no kuj ua raws li catalysts rau ntau txhiab tus tshuaj lom neeg tshwm sim hauv lub cev. Ntxiv mus, globulin proteins koom nrog hauv cov piam thaj metabolism, oxygen cia hauv cov leeg, thauj oxygen hauv cov ntshav, tiv thaiv kab mob, thiab lwm yam. Qee cov piv txwv ntawm globular proteins yog insulin, myoglobin, hemoglobin, transferrin, thiab immunoglobulins.
Dab tsi zoo sib xws ntawm Fibrous thiab Globular Proteins?
- Fibrous thiab globular proteins yog hom proteins uas muaj cov amino acids.
- Ob leeg ua haujlwm ua cov txheej txheem cov protein thiab cov protein ua haujlwm.
- Kuj, ob qho tib si muaj cov qauv thawj thiab theem nrab.
- Tsis tas li ntawd, lawv yog cov molecules tseem ceeb rau kev loj hlob thiab kev loj hlob ntawm cov kab mob nyob.
Qhov txawv ntawm Fibrous thiab Globular Proteins yog dab tsi?
Qhov sib txawv tseem ceeb ntawm fibrous thiab globular proteins yog cov proteins fibers yog insoluble hauv dej, tsis muaj zog hauv paus, thiab tsis muaj zog acids whereas, globular proteins yog soluble nyob rau hauv dej, bases, thiab acids. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm fibrous thiab globular proteins yog tias cov proteins uas muaj fiber ntau yog elongated strand zoo li cov proteins thaum globular proteins yog spherical proteins. Ntxiv mus, kev ua haujlwm, qhov sib txawv ntawm fibrous thiab globular proteins yog tias cov proteins fibrous pab hauv kev ua haujlwm xws li muab kev txhawb nqa thiab kev tiv thaiv, thiab lwm yam, thaum globular proteins yog lub luag haujlwm rau qee yam kev ua haujlwm metabolic xws li catalysis, thauj, thiab kev tswj hwm, thiab lwm yam.
Tsis tas li ntawd, globular proteins feem ntau muaj ob peb hom kev tsim theem nrab, thaum cov proteins fibrous muaj ib hom qauv thib ob. Yog li, qhov no kuj yog qhov sib txawv ntawm cov fibers thiab globular protein. Lwm qhov sib txawv ntawm fibrous thiab globular proteins yog tias muaj pes tsawg leeg ntawm ntau hom globular proteins yog siab dua li cov proteins fibrous. Ua cov protein ntau tshaj plaws nyob rau hauv tib neeg lub cev, fibrous proteins muaj tag nrho cov khoom loj dua li cov proteins globular. Yog li, qhov no yog ib qhov sib txawv ntawm fibrous thiab globular proteins.
Piv txwv rau cov proteins fibrous yog keratin thiab collagen, qhov piv txwv rau globular proteins yog hemoglobin thiab myoglobin. Tsis tas li ntawd, globular proteins muaj zog dua theem nrab thiab qib tertiary bonds dua li cov proteins fibrous; Yog li, globular proteins denature yooj yim dua li fibrous proteins. Yog li, qhov no kuj yog qhov sib txawv ntawm cov proteins fibrous thiab globular.
Summary – Fibrous vs Globular Proteins
Fibrous thiab globular proteins yog ob hom proteins uas muaj nyob hauv peb lub cev. Fibrous proteins yog elongated strand zoo li cov protein Ntawm qhov tod tes, globular proteins yog spherical nyob rau hauv cov duab. Tsis tas li ntawd, fibrous proteins yog insoluble nyob rau hauv dej, thaum globular proteins yog soluble nyob rau hauv dej. Ntxiv mus, globular proteins ua raws li catalysts ntawm biochemical cov tshuaj tiv thaiv thaum fibrous proteins muab structural functions. Piv rau globular proteins, fibrous proteins muaj ntau nyob rau hauv peb lub cev. Qhov no qhia txog qhov sib txawv ntawm fibrous thiab globular proteins.
