IVithamin B5 —— Isetyenziswa ngokubanzi iVithamin B yeSongezo.

I-Vitamin B5, eyaziwa ngokuba yi-pantothenic acid, yivithamini enyibilikayo emanzini eyinxalenye ye-B-vitamin complex. Idlala indima ebalulekileyo kwiinkqubo ezahlukeneyo zefiziyoloji emzimbeni.Nazi ezinye iinkalo eziphambili ze-Vitamin B5:

Indibaniselwano yeCoenzyme A:Omnye wemisebenzi ephambili ye-Vitamin B5 kukubandakanyeka kwayo kwi-synthesis ye-coenzyme A (CoA). I-CoA yimolekyuli edlala indima ebalulekileyo kwiimpendulo ezininzi ze-biochemical, kubandakanywa imetabolism ye-carbohydrates, amafutha kunye neeprotheni.

Ukuveliswa kwamandla:I-Vitamin B5 ibalulekile ekuguquleni ukutya kube ngamandla. Liyinxalenye ephambili kumjikelo weKrebs, oyinxalenye yokuphefumla kwamaselula. Lo mjikelo unoxanduva lokuvelisa i-adenosine triphosphate (ATP), eyona mali yamandla engundoqo yeeseli.

Ukwenziwa kwe-Acid enamafutha:ICoenzyme A, eyilwe ngoncedo lweVithamin B5, ibalulekile ekudibaneni kwamafutha acid. Oku kwenza ukuba i-B5 ibaluleke kakhulu ekuveliseni i-lipids, eyona nxalenye ebalulekileyo yeembrane zeseli kwaye idlala indima yokugcina amandla.

Ukwenziwa kweHormone:I-Vitamin B5 ibandakanyeka kwi-synthesis yeehomoni ezithile, ezifana neehomoni ze-steroid kunye ne-neurotransmitters. La mahomoni adlala indima ebalulekileyo kwimisebenzi eyahlukeneyo yomzimba, kubandakanya impendulo yoxinzelelo kunye nokulawula imo.

Impilo yolusu:I-Pantothenic acid ihlala ibandakanyiwe kwiimveliso zokhathalelo lwesikhumba ngenxa yeenzuzo zayo ezinokubakho kwimpilo yolusu. Kukholelwa ukuba negalelo ekugcinweni kolusu olunempilo ngokuxhasa ukuhlanganiswa kweeprotheni zesikhumba kunye ne-lipids.

Ukunyangwa Kwenxeba:I-Vitamin B5 idibene neenkqubo zokuphulukisa isilonda. Ibandakanyeka ekubunjweni kweeseli zesikhumba kunye nokulungiswa kwezicubu, okwenza kubaluleke ukubuyiswa kokulimala.

Imithombo:Imithombo emihle yokutya ye-Vitamin B5 ibandakanya inyama, iimveliso zobisi, amaqanda, iimbotyi, kunye neenkozo ezipheleleyo. Isasazwa ngokubanzi kwizidlo ezahlukeneyo, kwaye ukusilela kunqabile ngenxa yokuxhaphaka kwayo ekutyeni.

Ukunqongophala:Ukunqongophala kwe-Vitamin B5 ayiqhelekanga, njengoko ikhona kuluhlu olubanzi lokutya. Nangona kunjalo, iimpawu zisenokuquka ukudinwa, ukucaphuka, ukuba ndindisholo, nokuphazamiseka kwesisu.

Ukongeza:Kwezinye iimeko, izongezelelo ze-Vitamin B5 zingasetyenziselwa izizathu ezithile zempilo. Nangona kunjalo, kubalulekile ukubonisana nochwepheshe bezempilo ngaphambi kokuba uthathe naziphi na izongezo ukuze uthintele iziphumo ezibi ezinokubakho.

Ingakanani ivithamin B5 oyifunayo?

IBhodi yokutya kunye neZondlo kwiiZiko leSizwe leSayensi, ubuNjineli kunye neMedicine ibeke iingcebiso zokuthatha izondlo ezahlukeneyo. Bacebisa oku kulandelayo njengokuthatha okwaneleyo kwevithamin B5:
* Iinyanga ezi-6 nangaphantsi: 1.7 milligrams (mg).
* Iinyanga ezi-7-12: 1.8 mg.
*Iminyaka eyi-1–3: 2 mg.
* 4-8 iminyaka: 3 mg.
* I-9-13 iminyaka: 4 mg.
*Iminyaka eyi-14 nangaphezulu: 5 mg.
*Abantu abakhulelweyo: 6 mg.
*Abantu abancancisayo: 7 mg.
Akukho mda uphezulu usetelwe ivithamin B5. Oko kuthetha ukuba akukho bungqina baneleyo bokuqwalasela izixa eziphezulu zevithamin B5 njengomngcipheko omkhulu wezempilo. Kodwa ezinye izifundo ziye zaxela ukuba ukuba ngaphezu kwe-10 mg ngosuku lwezongezelelo ze-pantothenic acid kunokunxulunyaniswa nemiba yesisu, njengohudo oluncinci.
Isishwankathelo, i-vitamin B5 sisondlo esibalulekileyo esidlala indima ebalulekileyo kwiinkqubo ezininzi ze-physiological. Ukugcina ukutya okunesondlo okuquka iintlobo ngeentlobo zokutya kwanele ngokubanzi ukuhlangabezana neemfuno zeVitamin B5 zomzimba.
