Adenosine ikakemikari inokosha inonzi nucleoside iyo inowanzoitika mumasero ose emuviri. Iyo inoshandiswa kuendesa simba mukati memasero nekuumba mamolekemu seAdenosine triphosphate (ATP) uye adenosine diphosphate (ADP), uyewo ndeimwe yemakemikari, kana kuti neurotransmitters, mukati meuropi. Mukuwedzera kune mamwe mabasa akasiyana-siyana, adenosine yakawanikwa kuti inobudirira zvepanyama painkiller, inowedzera mitsipa yeropa, uye kubatsira kunodzora rwiyo rwemwoyo.
Mutumbi Unoita Sei Adenosine?
Adenosine yakasikwa zvakasikwa mukati memuviri kubva pakusangana adenine, chinhu chinonzi nitrogen-based, uye ribose, shuga. Mukuwedzera pakuva neurotransmitter, adenosine inorondedzerwa semakemikari inozivikanwa sa xanthine. Sero yese iri mumuviri inosanganisira adenosine iri mukati meDNA neRNA.
Adenosine Inogadzirisa Sei Kurara?
Adenosine ine basa rinokosha mune dzimwe nzira dzehupenyu hwehupenyu uye ndeimwe yevana neurotransmitter uye neuromodulators inobata maitiro akaoma ekurara, kunyanya kutanga kwehope. Muhuropi, inonzi neurotransmitter inhibitory, zvinoreva kuti inoshanda senhengo inotyisa yenhamo inodzvinyirira uye inovhara maitiro akawanda anobatana nekumuka. Nepo kumuka kwezinga reAdenosine muuropi rinomuka kweawa imwe uye naizvozvo rinotendwa kuti rinokonzerwa nekuwedzera kwehutano hunoita kuti munhu arambe akasvinuka kwenguva refu.
Panguva yekumuka, adenosine zvishoma nezvishoma zvinowedzera munzvimbo dzeuropi dzakakosha mukusimudzira kukwidza , kunyanya kuratidza kushandiswa kwemamiriro ezvinhu mu brain brain. Nepamusoro uye zvakakwirira, adenosine inhibits inomutsa uye inokonzera kurara. Zvadaro, mazinga adenosine anoderera munguva yehope. Nokudaro, masayendisiti ave achiwedzera kwenguva yakareba kuti mazinga akadai eAdenosine anokonzera kurara.
Zvechokwadi, caffeine inowanikwa mukofi, tei, nezvimwe zvinwiwa zvewaffeinate, ixanthine chemikemu yakadai sedenosine uye inoshanda kuti inzvidzire kurara nekuvhara chiito cheAdenosine mukati meuropi, iyo inowedzera kukurumidza.Kumwe mamwe mazwi, kana iwe ukanwa caffeine, iyo inobudirira pamigumisiro yaro inokurudzira nekuvhara uropi hwako hwekugadzirisa urinosine.
Nhanho dzehope
Kunyange zvazvo munhu akarara, ubongo hwake huchiri kushanda panguva dzakasiyana-siyana dzehope . Zvikamu zvakasiyana-siyana zvehope zvose zvinoshandisa zvinangwa zvakasiyana zvekuzorora nekudzorerwa. Nhanho 1 kurara kunoratidzirwa nekunetseka kumutsa nyore; panguva yechitsauko 2 kurara, mahupi europi anotanga kuderera uye kufamba kweziso kunogumira; vanhu vari muchitsauko 3 kurara zvinoratidza kutanga kwepfungwa dzenguva dzepfungwa dzakadzika; muchitsauko 4 kurara, kunonoka kwakanyanya kwehuropi hunoita; panguva yechikamu chechipiri, iyo inozivikanwawo sehope REM , zviroto zvinotanga kuitika, mitezo inowanzofa mitezo, nguva inokurumidza kupera, uye kufema kunowedzera uye kusina kujeka.
Muyero weAdenosine metabolism unoratidzika kuti unobatsira zvakananga kana kuti uone hutano hwehope huru, vatsvakurudzi vakawana, pamwe chete nehutano hwemunhu hwekurara kusara.
