himoglobin (angrezi: Hemoglobin) ek prakar ka protin hota hai, jisamen ayaran upasthit rahata hai. yah aauksijan ko sharir ke ek hisse se doosare hisse men pahunchata hai. ise snkshipt roop se 'echabi' ya 'echajibi' bhi kaha jata hai. rakt men maujood himoglobin phephadon ya gilon se sharir ke shesh bhag ko[1] aauksijan ka parivahan karata hai, jahan vah koshikaon ke prayog ke liye aauksijan ko mukt kar deta hai.

  • yah prishthavnshiyon ki lal rakt koshikaon aur kuchh aprishthavnshiyon ke ootakon men paya jane vala lauh yukt aauksijan ka parivahan karane vala dhatu protin hai.
  • stanadhariyon men lal rakt koshikaon ke shushk bhag ka lagabhag 97 pratishat aur kul bhag[2] ka lagabhag 35 pratishat protin se nirmit hota hai.
  • himoglobin lal rakt koshikaon aur unako utpann karane vali projenitar rekhaon ke bahar bhi paee jati hai.
  • kuchh any koshikaon men jo himoglobin yukt hoti hain, sabastainshiya naigra ke e9 dopaminarjik nyooran, maikrophaij, alviyolar koshikaen aur gurdon ki mesainjiyal koshikaen shamil hain. in ootakon men himoglobin ki bhoomika aauksijan ke parivahan ki jagah entiaksidaint aur lauh chayapachay ke niyntrak ke roop men hoti hai.

rachana

himoglobin anu haidrojan, karban, naitrojan, salphar aur aauksijan ke karib 10,000 paramanuon se milakar bana hota hai aur ye sabhi paramanu badi taratib se ayaran ke charon paramanuon ke as-pas rakhe hote hain. lekin ayaran ke in char paramanuon ko itane sare paramanuon ki zaroorat kyon hoti hai? amataur par jab paramanu men ilektraaun ki snkhya badhati ya ghatati hai, to vah ayan ban jata hai. himoglobin men ayaran ke paramanu, ayan ke roop men hote hain aur unhen kaboo men rakhana zaroori hota hai. kyonki agar inhen yoon hi chhod diya jae to ye ayan, koshika ko nukasan pahuncha sakate hain. ye char ayan, char sakht tashtari ke bich jade hote hain. ye charon tashtariyan himoglobin anu men is tarah savadhani se bithayi huee hoti hain ki aauksijan ke anu to ayan tak pahunch pate hain, lekin jal ke anu is tak nahin pahunchate. yahi vajah hai ki ayan men zng nahin lagata.

kary pranali

himoglobin anu ka saphar tab shuroo hota hai, jab lal rakt koshikaen phephadon ke ailaviolai par pahunchati hain. sans lene par aauksijan ke dheron anu phephadon men pahunchate hain. yah chhote-chhote anu lal rakt koshika men pahunchate hain. himoglobin ke andar ayaran ke paramanu hote hain aur aauksijan ke anu unase ja chipakate hain. himoglobin men paya jane vala ayaran svayn aauksijan se nahin judata ya chhutata. agar ayaran ke paramanu, ayan ke roop men maujood n hote, to himoglobin anu kisi kam ka nahin hota. ayan bakhoobi himoglobin men jade hote hain, isalie ye rakt ki naliyon se hote hue aauksijan ko ootakon tak asani se pahunchate hain. jaise hi lal rakt koshikaen dhamaniyon se hokar rakt ki chhoti-chhoti naliyon men ati hain, to koshika ke as-pas ka tapaman badal jata hai. phephadon ke mukabale naliyon men tapaman garam hota hai. sath hi, naliyon men aauksijan ki kami hoti hai aur karban daiaauksaid se banane vale aml ki matra zyada hoti hai. ye badalav himoglobin ke lie ek snket hota hai ki unhen ab aauksijan ko mukt karana hai.[3]

aauksijan ko sahi jagah tak pahunchane ke bad, himoglobin apana akar ek bar phir badal leta hai. himoglobin se matr itani hi jagah khulati hai ki aauksijan bahar nikal jae aur phir yah jagah band ho jati hai. aisa isalie hota hai ki aauksijan ka koee anu andar n a sake. vapasi yatra men himoglobin karban daiaauksaid ko utha le jata hai. isake bad, lal rakh‍t koshikaen dobara phephadon men pahunchati hain, jahan himoglobin, karban daiaauksaid ko chhodakar phir se jivan kayam rakhane vali aauksijan ko ekatr karata hai. ek lal rakh‍t koshika karib 120 din tak jinda rahati hai. is dauran hazaron bar phephadon se lekar ootakon tak unaka saphar jari rahata hai.

kami ke lakshan

svasth purush ke sharir men 13-16 v mahila men 12-14 miligram prati desilitar himoglobin hona chahie. hath-panv men soojan, ekagrata ka abhav, jaldi thakana v sans phoolana adi sharir men himoglobin ki kami ke lakshan hain.
