Kwiphulo lethu lempilo engcono kunye nokuphila kakuhle, sihlala sidibana neekhompawundi ezahlukeneyo kunye neemolekyuli ezidlala indima ebalulekileyo ekwandiseni amandla emizimba yethu. I-Adenosine, i-nucleoside yendalo, yenye yeemolekyuli ezinjalo efumana ingqalelo engakumbi ngenxa yeenzuzo zayo ezibalulekileyo zempilo. Ukususela ekukhuthazeni impilo yentliziyo ukuya ekuboneleleni ngamandla kunye nokuxhasa imetabolism, i-adenosine inamandla amakhulu okuqinisa imizimba yethu ukusuka ngaphakathi ukuya ngaphandle.
I-Adenosine yikhompawundi yendalo efumaneka phantse kuzo zonke iiseli emzimbeni wethu. Yimolekyuli ebalulekileyo ebandakanyeka kwiinkqubo ezahlukeneyo ze-physiological, kubandakanya ukuhanjiswa kwamandla kunye nokulawulwa kokuhamba kwegazi.
I-Adenosine, i-nucleoside, yenziwe yimolekyuli yeswekile (ribose) kunye ne-adenine, enye yeziseko ezine ezifumaneka kwi-DNA kunye ne-RNA. Idlala indima ebalulekileyo ekuvelisweni kwe-adenosine triphosphate (ATP), imali yamandla ephambili yeeseli zethu. Xa imizimba yethu ifuna amandla, i-ATP iyahlulwahlulwa ibe yi-adenosine diphosphate (ADP) kunye namaqela e-phosphate akhululekileyo, ikhupha amandla okunika amandla imisebenzi eyahlukeneyo ye-metabolic.
Ukongeza kwindima yayo kwimetabolism yamandla, i-adenosine ikwabandakanyeka kwiinkqubo zokubonisa imiqondiso emizimbeni yethu. Isebenza njenge-neurotransmitter, isithunywa sekhemikhali esithwala imiqondiso phakathi kweeseli zemithambo-luvo. I-Adenosine inamandla okubophelela kwii-receptors ezithile engqondweni, ibangela iziphumo ezahlukeneyo kwimisebenzi yemithambo-luvo kwaye ichaphazela iipatheni zokulala, ukuvuka, kunye nokuvuka.
Kwicandelo lezonyango, i-adenosine isetyenziswa kakhulu njengeyeza ngexesha lovavanyo loxinzelelo lwentliziyo. Inikwa umthambo ukuze yonyuse ukuhamba kwegazi ukuya entliziyweni okwethutyana kwaye ibangele uxinzelelo, nto leyo evumela iingcali zezempilo ukuba zihlole ukusebenza kwentliziyo. I-Adenosine inobomi obufutshane kwaye iziphumo zayo zibuyela umva ngokukhawuleza, nto leyo eyenza ukuba ibe sisixhobo esikhuselekileyo nesisebenzayo kwiinkqubo zokuxilonga ezinjalo.
Ukususela kwiinkqubo zokudluliselwa kwamandla ezilawulwa ziimolekyuli ezifana ne-AMP, i-ADP kunye ne-ATP, ukuya kwindima yolawulo edlalwa yi-cAMP kwimiqondiso yeseli, i-adenosine isalokhu iyinxalenye entsonkothileyo neyimfuneko yoomatshini abantsonkothileyo bobomi.
●I-Adenosine monophosphate (AMP): I-AMP yi-metabolite ebalulekileyo ebandakanyeka ekudlulisweni kwamandla ngaphakathi kweseli. Ngokubamba amandla akhutshwayo ngexesha leenkqubo zeseli, ii-AMP zidlala indima ebalulekileyo kwi-nucleotide biosynthesis, i-protein phosphorylation, kunye ne-signal transduction. Ukongeza, yi-molecule yokuqala yokwenziwa kwe-adenosine triphosphate (ATP), eyona mali iphambili yamandla kwizinto eziphilayo.
