Comparison of amino acids contents in barley and wheat
Komparacija sadržaja aminokiselina kod ječma i pšenice
Abstract
Variability of amino acids composition
of 6 barley and 6 wheat divergent genotypes were
identified by using method of chromatography.
Concentration of identified amino acids was
established by method of spectrophotometry. Total
concentration of free amino acids was determined
by standard curved line for tyrosine while
concentration for each amino acid was determined
by using of standard curved line for glycine.
Qualitative and quantitative analysis of amino
acids showed that glutamic acid, proline,
threonine, norvaline, tryptophan, were the most
present in seeds of analyzed cereal species
cultivars. Quantity of free amino acid in wheat
varies in the ratio from 35 to 92 mg/ml and in
barley from 41 to 81 mg/ml. Concentration of
glutamic acid in wheat was 6.5 mg/ml and was
higher than contents of other amino acids. In
barley cultivars the highest concentration was
established for amino acids proline (12.5 mg/ml)
Varijabilnost sadržaja aminokiselina kod
6 sorti ječma i 6 divergentnih genotipova pšenice je
identifikovana korišćenjem metode hromatogragije.
Koncentracija amino kiselina je ustanovljena
metodom spektrofotometrije. Ukupna koncentracija
slobodnih aminokiselina je odredjivana pomoću
standardne krive linije za tirozin, dok je
koncentracija pojedinih aminokiselina odredjivana
korišćenjemstandardne krive linije za glicin.
Kvalitativna i kvantitativna anliza aminokiselina je
pokazala da su u semenu ječma i pšenice od
slobodnih aminokiselina najzastupljenije:
glutaminska kiselina, prolin, treonin, norvalin,
triptofan. Kvantitet aminokiselina kod pšenice
varira u rasponu od 35-92 mg/ml a kod ispitivanih
sorti ječma od 41 do 81 mg/ml. Koncentracija
glutaminske kiseline kod pšenice bila je najveća 6.5
mg/ml u poredjenju sa drugim aminokiselinama.
Kod sorti ječma najveća koncetracija je
ustanovljena za aminokiselinu prolin (12.5 mg/ml).
