Ikhwalithi ephezulu ye-Amino Acid Powder L-leucine
Incazelo Yomkhiqizo
I-Leucineiyi-amino acid ebalulekile esetshenziswa ku-biosynthesis yamaprotheni. I-Leucine iyi-α-amino acid, okusho ukuthi iqukethe iqembu le-α-amino (elikuyi-protonated −NH3+ifomu ngaphansi kwezimo zebhayoloji), iqembu le-α-carboxylic acid (eliku-deprotonated −COO−ifomu ngaphansi kwezimo zebhayoloji), kanye neqembu le-isobutyl leketango eliseceleni, elenza libe i-amino acid engeyona i-polar aliphatic. Ibalulekile kubantu, okusho ukuthi umzimba awukwazi ukuyihlanganisa: kufanele itholakale ekudleni. Imithombo yokudla yabantu ukudla okuqukethe amaprotheni, njengenyama, imikhiqizo yobisi, imikhiqizo yesoya, nobhontshisi nezinye izidumba. Ifakwe ikhodi ngamakhodi u-UUA, UUG, CUU, CUC, CUA, kanye ne-CUG.

Umsebenzi
I-Leucine iyi-amino acid ebalulekile ekwakheni amaprotheni. Ukwengeza, ngokufanayo namanye ama-amino acid, i-carbon skeleton ye-leucine ingasetshenziswa ukukhiqiza i-ATP. Kodwa-ke, i-leucine ingaphinda ilawule izinqubo eziningana zamaselula ezifana nokuhlanganiswa kwamaprotheni, ukuvuselelwa kwezicubu, kanye ne-metabolism.
