Tulaga maualuga Amino Acid Powder L-leucine
Fa'amatalaga o oloa
Leucineo se amino acid taua lea e faʻaaogaina i le biosynthesis o polotini. Leucine o se α-amino acid, o lona uiga o loʻo i ai se vaega α-amino (lea o loʻo i totonu o le protonated −NH.3+faia i lalo o tulaga olaola), o se vaega α-carboxylic acid (lea o loo i totonu o le deprotonated -COO.−fa'atupu i lalo o tulaga olaola), ma se vaega o le isobutyl filifili itu, ma avea ai o se amino acid aliphatic non-polar. E taua i tagata, o lona uiga e le mafai e le tino ona tuʻufaʻatasia: e tatau ona maua mai meaʻai. O mea'ai a tagata o mea'ai ia e iai porotini, e pei o aano o manufasi, mea'ai susu, oloa soya, ma pi ma isi leki. O lo'o fa'ailogaina e codons UUA, UUG, CUU, CUC, CUA, ma le CUG.

Galuega
Leucine o se amino acid taua mo le faʻapipiʻiina o polotini. E le gata i lea, e tutusa ma isi amino acids, o le skeleton carbon o le leucine e mafai ona faʻaaogaina e gaosia ai le ATP. Ae ui i lea, o le leucine e mafai foʻi ona faʻatonutonuina le tele o gaioiga feaveaʻi e pei o le protein synthesis, faʻafouina o le tino, ma le metabolism.
