Ama-amaminesziyinhlanganisela ebalulekile emzimbeni womuntu. Akhona ezinhlobonhlobo zamamolekyuli aphilayo futhi adlala izindima ezihlukahlukene. Ama-amine aqukethe amaqembu e-amino (-NH2) namaqembu e-hydrocarbon noma okuphuma ku-hydrocarbon. Zisebenza ngamakhemikhali futhi kulula ukusabela ngamakhemikhali.
Emzimbeni womuntu, ama-amine anemisebenzi elandelayo:
1. Hlanganisa amaprotheni: Ama-amine amayunithi ayisisekelo akha amaprotheni. Amaprotheni asemzimbeni womuntu akhiwe ama-amino acid ayisisekelo angama-20, angu-19 kuwo aqukethe amaqembu amino.
2.Ukudluliselwa kwe-Neurotransmitter: Amanye ama-amine, njenge-dopamine, i-norepinephrine, i-5-hydroxytryptamine, njll., ama-neurotransmitters emzimbeni womuntu. Asebenza njengezithunywa zamakhemikhali ukuze adlulisele ulwazi phakathi kwama-neuron futhi alawule imisebenzi ehlukahlukene yomzimba yomzimba.
3.Bamba iqhaza ezinqubweni ze-metabolic: Amanye ama-amine, njenge-amino acid decarboxylase, adlala indima ebalulekile ezinqubweni ze-metabolic. Bangakwazi ukugqugquzela i-decarboxylation yama-amino acid ukukhiqiza amandla adingwa izinto eziphilayo.
4.Lawula ukucindezelwa kwegazi nokushaya kwenhliziyo: Ama-amine, njenge-norepinephrine, angakhuthaza i-vasoconstriction futhi andise umfutho wegazi. Ngaphezu kwalokho, ama-amine nawo angasheshisa ukushaya kwenhliziyo futhi agcine ukujikeleza kwegazi emzimbeni.
5.Ukulawulwa kwamasosha omzimba: Amanye ama-amine, njenge-histamine, adlala indima ebalulekile emasosheni omzimba. Ukukhululwa kwe-histamine kungabangela ukungezwani komzimba futhi kukhuthaze ukuvuvukala.
6.Ukulawulwa kweHormone: Ama-amine, njengamahomoni egilo, angamahomoni abalulekile ekugcineni imisebenzi evamile yomzimba womuntu. Amahomoni e-thyroid anomphumela olawulayo ekukhuleni komuntu, ekuthuthukisweni nasekusebenzeni komzimba.
Kunezinhlobo eziningi zeamamaminesemzimbeni womuntu, futhi asebenza ndawonye ukuze asekele ukusebenza okuvamile kokuphila. Kodwa-ke, lapho izinga lama-amine lingalingani, lingase liholele ezifweni ezithile, njengezifo ze-neurodeergenerative, izifo zenhliziyo, izifo zamasosha omzimba, njll. Ngakho-ke, ukugcina ibhalansi yama-amine kubalulekile ekugcineni impilo enhle.
