Ib qho me me molecule (los yog metabolite) tsawg molecular hnyav organic compound, feem ntau koom nrog hauv cov txheej txheem lom neeg ua ib qho substrate lossis khoom. Qee qhov piv txwv me me molecules suav nrog: qab zib, lipids, amino acids, fatty acids, phenolic compounds, alkaloids thiab ntau ntxiv (Daim duab 2).
Kuj nug, dab tsi yog cov molecules loj ua los ntawm me me molecules hu ua?
Ib tug loj molecule ua los ntawm me me molecules yog hu ua a macromolecule . Macromolecules kuj qee zaum hu ua polymers , thiab me me molecule
Ib tug kuj nug, qhov txawv ntawm qhov loj thiab me molecules yog dab tsi? Piv txwv li, me me molecule Cov tshuaj feem ntau yog tsim los ntawm 20 txog 100 atoms xwb. Me me biologics, xws li cov tshuaj hormones, feem ntau yog tsim los ntawm 200 txog 3000 atoms, thaum loj biologics, xws li cov tshuaj tiv thaiv kab mob, feem ntau muaj li ntawm 5000 txog 50,000 atoms.
Tom qab, lo lus nug yog, dab tsi yog me me molecule pharmacology?
Hauv cov teb ntawm molecular biology thiab kws tshuaj , a me me molecule yog qis molecular hnyav (< 900 daltons) organic compound uas yuav tswj tau cov txheej txheem lom neeg, nrog rau qhov loj ntawm qhov kev txiav txim ntawm 1 nm.
Cov molecules loj hu ua dab tsi?
Ib qho macromolecule yog heev loj molecule , xws li cov protein, feem ntau tsim los ntawm polymerization ntawm cov subunits me hu ua cov monomers. Feem ntau cov macromolecules hauv biochemistry yog biopolymers (nucleic acids, proteins, thiab carbohydrates) thiab loj non-polymeric molecules (xws li lipids thiab macrocycles).

Dab tsi yog qhov sib txawv ntawm cov rog yuav cuam tshuam rau kev sib cuam tshuam ntawm cov dej molecules?
1 Teb. Qhov tseeb, dej muaj tag nrho peb hom kev sib xyaw ua ke, nrog qhov muaj zog tshaj plaws yog hydrogen bonding. Txhua yam muaj London dispersion yuam cov kev sib cuam tshuam tsis muaj zog yog ib ntus dipoles uas tsim los ntawm kev hloov ntawm electrons nyob rau hauv ib lub molecule
Dab tsi ntawm cov molecules tsim cov nucleic acids?
Nucleic acids yog cov molecules tsim los ntawm nucleotides uas ncaj qha cov haujlwm hauv cellular xws li kev faib cell thiab kev tsim cov protein. Txhua nucleotide yog tsim los ntawm pentose qab zib, nitrogenous puag, thiab phosphate pawg. Muaj ob hom nucleic acids: DNA thiab RNA
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog txoj kev pub dawb rau cov molecules hauv cov roj zoo tagnrho?
Hauv cov pa roj, cov molecules sib tsoo nrog ib leeg. Momentum thiab lub zog tau txais kev cawmdim hauv cov kev sib tsoo no, yog li txoj cai roj zoo tagnrho tseem siv tau. Qhov txhais tau tias dawb txoj kev λ yog qhov nruab nrab ntawm qhov kev ncua deb ib qho kev mus los ntawm kev sib tsoo. Yog hais tias 2 hais, txhua lub vojvoog R, tuaj nyob rau hauv 2R ntawm ib leeg, ces lawv sib tsoo
Dab tsi yog lub zog tso tawm cov txheej txheem uas rhuav tshem cov molecules loj rau hauv cov me?
Catabolic Reactions. Cov tshuaj tiv thaiv Catabolic rhuav tshem cov organic molecules loj rau hauv cov molecules me, tso tawm lub zog uas muaj nyob rau hauv cov tshuaj bonds
