Ukubuka konke

I-hormone yokukhula (GH) iyi-hormone yamaprotheni ekhishwe kwi-anterior pituitary gland ngaphansi kolawulo lwe-hypothalamus.Ezinganeni, i-GH inemiphumela ekhuthaza ukukhula emzimbeni. Kuvusa uketshezi lwama-somatomedins avela esibindini, okuwumndeni wama-hormone afana ne-insulin factor (IGF). Lokhu, kanye ne-GH ne-hormone ye-thyroid, kushukumisa ukukhula okulinganayo kwamathambo ezinganeni.

Kubantu abadala, i-GH ivuselela amaprotheni synthesis emisipheni kanye nokukhishwa kwamafutha acid avela kwizicubu ze-adipose (imiphumela ye-anabolic). Ivimbela ukuthathwa kweglucose ngemisipha ngenkathi kukhuthazwa ukutholwa kwama-amino acid. Ama-amino acid asetshenziswa ekuhlanganisweni kwamaprotheni, kanye nemisipha eshintshela ekusebenziseni okunamafutha acid njengomthombo wamandla. Ukuvikeleka kwe-GH kwenzeka nge-pulsatile (imfihlo emfushane, egxilile) nangendlela engajwayelekile. Ngakho-ke, isivivinyo esisodwa sezinga le-GH ngokuvamile alenziwa.
