Antioxidants Inodzivirira Masero Edu

Mahara radicals ndiwo mudzi wematambudziko mazhinji ehutano. Vanorwisa masero edu uye vanogona kuita kuti asashande. Verenga izvozvi kuti ndeapi ma antioxidants anopa dziviriro yakavimbika uye kuti ndezvipi zvekudya zvine mazviri!

Mahara radicals anorwisa masero uye antioxidants anoadzivirira

Mahara radicals mamorekuru ane okisijeni asina kugadzikana zvine njodzi nekuti ari kupotsa elekitironi muchimiro chavo chemakemikari. Hauna kukwana. Saka vanotsvaga erekitironi rinoenderana kuti rive rakakwana zvakare.

Mukutsvaga uku kwemudiwa anosunga akakodzera, mahara radicals ane hutsinye uye, pamusoro pezvose, anokasira. Kana yemahara radical ikaumbwa, zvinotora rekodhi-kutyora 10-11 masekonzi (0.00000000001 masekonzi) kurwisa chero munhu akabatwa.

Inobvuta zvine hukasha erekitironi yainoda kubva kune inotevera yakanyanya kusimba molecule (semuenzaniso mamorekuru e cell membrane, mapuroteni, kana DNA). Kubira maerekitironi uku kunonzi oxidation. Sezvo oxidation - nekukurumidza kana ichinge yadarika mwero unoshivirira - inoisa kunetsa pamuviri, inonzi oxidative kusagadzikana.

Mahara radicals uye mhedzisiro yawo kune chipenyu

Morekuru yakabiwa iye zvino yashaya elekitironi. Saka ikozvino inove yemahara radical pachayo uye inoenda kunotsvaga munhu akabatwa kubva kwaanogona kubira erekitironi.

Nenzira iyi, kuita kwecheni ine ngozi kunotangwa. Yakanyanya kuwanda yemahara radicals saka inogona kukonzeresa isingaverengeke ketani maitiro, ayo anogona kupedzisira atungamira kune yakakwira mwero weoxidative kusagadzikana uye nekudaro kune kunotevera kukuvara kwakanyanya mumuviri:

• Kurambidzwa kwesero kushanda kana kufa kwesero nekuda kwekukuvara kwe membrane
• Kukuvadzwa kweDNA kunokonzera kusadzora kupatsanurwa kwesero (kukura kwekenza)
• kusashanda kwema enzymes
• Yakaderedzwa kuumbwa kwe endogenous mapuroteni
• Kuparadza kwema receptors pane sero pamusoro: Zvinogamuchira mapuroteni chaiwo pasero pamusoro, umo - zvinoenderana nekiyi uye kiyi musimboti - akakodzera mahormone, enzymes, kana zvimwe zvinhu zvinogona kumisa. Iyi docking inotumira chaiyo chiratidzo kune sero. Semuenzaniso, masero ane ma receptors ehomoni insulin. Kana insulin inosunga kune aya ma receptors, sero rinowana chiratidzo chekutora glucose. Iyo yekuvhara-uye-kiyi musimboti yakafanana nemhando yekodhi iyo inoitirwa kuti ive nechokwadi chekuti zvimwe chete zvinhu zvinogona kusunga kune inoenderana receptor uye chete "zvakatenderwa" zvinhu zvinoendeswa mumaseru. Zvinhu (semuchetura) zvisina "kiyi" zvinorambidzwa kupinda mumaseru. Mahara radicals anogona kuparadza ma receptors uye nekudaro kudzivirira kutapurirana kwechiratidzo. Kana, semuenzaniso, ma receptors e insulin akaparadzwa, sero riri mubvunzo harichagashira chero glucose, i.e. hapasisina mafuta, uye rinofa.
  MaAntioxidants anodiwa nekuti mahara radicals anokuvadza muviri
  Mahara radicals anokonzera kukanganisa kwakawanda kumiviri yedu. Kana iwe ukazviziva iwe uye matambudziko ako mune rondedzero iri pazasi, iwe unofanirwa kuedza kudya zvine hutano.

Antioxidants inodzivirira ganda

Kunyanya, kukuvadzwa uku kunokonzerwa nemahara radicals kunozviratidza, semuenzaniso, mune yakaunyana uye grey ganda rinoshaya chero elasticity, mune kushaya simba kwevenous, uye varicose tsinga, sezvo mahara radicals inokuvadzawo tsinga dzeropa. Iyo yekupedzisira inogonawo kuzviratidza mukukwira kweropa uye mamwe matambudziko emwoyo.

Antioxidants inodzivirira maziso

Kana midziyo yakaisvonaka yemaziso inobatwa, zviratidzo zvekuderera uye kuderedzwa kwekuona kunoitika ipapo.

Antioxidants inogona kudzivirira kubva kugomarara

Kana iyo DNA yemasero yakakuvadzwa nemahara radicals, izvi zvinogona kutungamirira kune inonzi inonzi cell degeneration. Kana maitiro emuviri wega, ayo anofanirwa kuvhara sero iri rakarasika, akatadza, sero iri rinogona kuwanda uye bundu rinoita gomarara. Verenga zvakare: Mavhitamini anodzivirira kubva kugomarara. MaAntioxidants akaratidzwa kudzivirira kubva kugomarara muchidzidzo ichi (5Trusted Source).

Iyi sarudzo diki yezvinoparadza zvinokonzeresa zvemahara radicals inoratidza kuti hapazove nekamwe kiriniki mufananidzo uyo mahara radicals HAZVINA kubatanidzwa mukugadzira.

Antioxidants vabatsiri vari mukuda kukuru

Chete antioxidant (inonziwo free radical scavenger) inogona kukanganisa kuita kweketani yemahara radicals nekudaro kudzivirira kukuvara kwesero.

Saka mafree radicals asati abvuta erekitironi kubva musero membrane kana kubva muprotein yakakosha yemuviri, ma antioxidants anopinda nekuzvidira kupa imwe yemaerekitironi awo kune yakasununguka radical. Saka ma antioxidants anopa maerekitironi awo zviri nyore kupfuura sero membrane kana DNA inoita.

Nenzira iyi, masero emuviri anoramba akadzivirirwa kana yakakwana antioxidants iripo.

Antioxidant inovimbisa kuti masero emuviri anodzivirirwa kubva kumahara radical kurwiswa nenzira mbiri:

MaAntioxidants anopa maerekitironi nokuzvidira kudzivirira maseru.

MaAntioxidants pachawo haatombove emahara radical kana - mushure mekunge vasiya erekitironi - anobva adzoserwa muchimiro chavo che antioxidant uye nekudaro vanova nechokwadi chekupera kwechimbichimbi kune njodzi cheni yekuita. Semuenzaniso, kana iyo antioxidant vhitamini E yakamisa radical, ichava kwenguva pfupi mahara radical pachayo, iyo inonzi vhitamini E radical. Zvisinei, izvi hazvigoni kuva nemigumisiro yakaipa, sezvo inokurumidza kudzorerwa kumhando yayo yepakutanga ne vitamini C kuitira kuti iite zvakare se antioxidant. Uku kuvandudzwa kwevhitamini E radical nderimwe remabasa akakosha evhitamini C.
Yemahara radicals uye antioxidants mune prehistoric nguva
Mahara radicals anowana rap yakaipa uye zvinoita senge hapana chatinoda kutarisa pane kupfuura kuvabvisa.

Chaizvoizvo, zvisinei, maradicals akasununguka ave aripo kwenguva refu (kana kuti refu) sezvave pane upenyu pasi pano.

Mahara radicals uye antioxidants munguva dzazvino

Nhasi mamiriro ezvinhu akasiyana chaizvo. Vanhu vanoputa fodya, vanonwa doro, vanodya zvekudya zvisingavaki muviri, vanogara munzvimbo dzine huwandu hwemotokari uye nekubuda kwemhepo yakawandisa, zvinoratidzika - zvinosangana nekunyungudika kweradioactive makore makumi maviri neshanu ega ega, uye vanotora mishonga kurwisa kunyangwe kadikidiki.

Zvinoenderana nefungidziro dzekuchengetedza, rimwe nerimwe remasero edu emuviri matiririyoni zana rava kurwiswa nezviuru zvakati wandei zvemahara radicals zuva rega rega. Huwandu hukuru hwe antioxidants saka hunodiwa kuti uise "radical" uto panzvimbo yayo.

Nehurombo, nhasi isu hatisi kungoratidzwa kune akawanda uye akawanda emahara radicals, asi panguva imwe chete kudya kune mashoma uye mashoma antioxidants uye, nekuda kwekukuvadza kwavo, kuremedza muviri nekuwedzera mahara radicals.

Antioxidants mukudya

Kunyange zvazvo kudya kwemazuva ano kunobva pazviyo, mukaka, uye nyama kunopa kudya, mapuroteni, makabhohaidhiretsi, uye mafuta akawanda, antioxidants ishoma uye iri kure. Saka vanhu vari kuita buxomer uye buxomer, asi panguva imwechete vachirwara zvakanyanya. Yakatove yakaratidzwa pano kuti mukaka unodzivisa antioxidant basa remuchero.

Chinoshaikwa kusarudzwa kwakapfuma kwemiriwo yakawanda nembesa, michero nemiti yemusango, mafuta echisikigo nemafuta pamwe nembeu dzemafuta nenzungu. Zvese zvezvikafu izvi zvakaringana uye zvakapfuma masosi eakakosha antioxidants. Chikafu chinobva pakudya kwechikafu, saka, chinodzivirira kurwara uye kuchembera nguva isati yakwana.

Mahara radicals anogonawo kubatsira

Zvisinei, mahara radicals haasi nguva dzose akaipa. Sezvinowanzoitika, huwandu hunoita musiyano pakati pezvakanaka nezvakaipa.

Aya ndiwo magadzirirwo anoita muviri wedu akawanda emahara radicals pachawo panguva dzemazuva ese zviitiko:

Mahara radicals mumasero ekufema

Masero edu anogara achida oxygen kuti abudise simba. Mahara radicals anoumbwawo senge-chigadzirwa - zvakanyanya kudaro, iyo yakakwirira kugadzirwa kwesimba mumuviri.

Kugadzirwa kwesimba kunoshanduka zvichienderana nezvinodiwa. Semuenzaniso, inowedzera mumamiriro ezvinhu anonetsa, panguva yemitambo, kana paunenge uchirwara. Naizvozvo, i.a. zvinhu zvitatu izvi zvinowedzera huwandu hwemahara radicals zvakasikwa.

Mahara radicals anogona kuparadza mabhakitiriya nemavhairasi

Uyezve, mahara radicals haangosikwa senge-chigadzirwa chemamwe mabasa emuviri. Izvo zvinogadzirwa nemuviri wedu - zvakanyanya neiyo immune system - kune chinangwa chaicho.

Mahara radicals haango rwisa zvimiro zvemuviri zvine hutano asi anokwanisa zvakare kuparadza hutachiona hwakadai sehutsinye hwebhakitiriya kana mavhairasi kana kumisa maitiro ekuzvimba. Saka apa ndipo panodiwa mahara radicals uye anobatsira.

Ndeapi ma antioxidants aripo?

Chii chekutanga chinouya mupfungwa dzako paunonzwa izwi rekuti "antioxidants"? Vitamin C? Vitamin C ndeye antioxidant. Ichokwadi. Nekudaro, iyo antioxidant mhedzisiro haina kunge yakanyanya kuremedza sezvo mukurumbira wayo ungaite kuti utende.

Apuro, semuenzaniso, rine mamilligrams gumi evhitamini C, asi antioxidant mhedzisiro yaro yakakura zvakapetwa kakawanda. Yakakura zvekuti kana iyo antioxidant effect yakabva kuvhitamini C chete, yaizofanira kunge iine 10 milligrams yevhitamini C, izvo zvisiri izvo.

Sezviri pachena, maapuro anewo huwandu hwezvimwe zvinhu zvine simba rakasimba re antioxidant pane vhitamini C. Iri boka rinoshanda zvikuru rinosanganisira, semuenzaniso, ma enzymes uye polyphenols ari ezvechipiri chirimwa zvinhu (e.g. flavonoids, anthocyanins, isoflavones, nezvimwewo).

Iwo mashanu mapoka makuru eanonyanya kushanda antioxidants ndeaya

• Vitamini
• zvicherwa
• trace zvinhu
• enzymes
• Phytochemicals (inonziwo bioactive plant compounds kana phytochemicals) yakatanga kugadzirwa nechirimwa kana muchero kudzivirira icho chirimwa kana michero kubva pakurwiswa kwefungal, zvipembenene, kana UV mwaranzi. Mamwe ma phytochemicals ane antioxidant effect ndiwo mavara ari mumiti, ayo ane ruvara rwemaruva, mashizha, kana michero. Mumuviri wemunhu, izvi zvinomera antioxidants zvinogona kubatsira kugara uine hutano uye wakasvinura.
