fish larvae have a high requirement of amino acid (aa) for energy production and growth. this study was aimed to increase knowledge of aa profile during feral carp larval ontogeny and estimate larval aa requirements. larvae were collected randomly at 1, 3, 7, 11, 15, 19, 26 and 33 days post hatch for growth and aa analysis. the composition of total aa changed significantly during ontogeny. the ...

the thermodynamic functions such as enthalpy (h), gibbs free energy (g) and entropy (s) of serineand threonine amino acids were theoretically studied at different condition (solvents andtemperatures) by using gussian o3, software. first, the structural optimization of isolated serine andthreonine were done in the gas phase by using the hartree-fock (hf) level of theory with 3-21g, 6-31g and 6-3...

In this study rainbow trout (Oncorhynchus mykiss) fillets were vacuum packed, frozen and stored at -18°C and  the effect of this packaging method on proximate composition, fatty acids and amino acid profile and their changes compared to control conditions during 9 months of storage were studied. The results showed that 18 fatty acids were identified. The unsaturated fatty acid (UFA) were 56.77 ...

structure with three long leops. The amino acids making up PL 47 are richer in hydrophobic amino acids and glutamic acid than BsPel. The hydropathy profile of PL 47 indicated that the amino acid sequences around putatiye calcium binding sites are more hydrophobic than the same region of BsPel. The gene product expressed in B. subtilts as the host was stable up to 700C and the reaction was optim...

The impact of PGF2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, Bombyx mori L. were investigated in the present experiment. The effect of PGF2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. The enhanced activity levels of amin...

The plasma free amino acid (PFAA) profile is affected by various nutritional conditions, such as the dietary energy balance. Regarding the clinical use of PFAA profiling, it is of concern that differences in food ingestion patterns may generate systematic errors in a plasma amino acid profile and constitute a confounding factor in assessment. In this study, the overnight impact of the dietary e...

Appreciated for its exotic flavor and considered a nutrient-rich food, Brazil nut is composed mostly of unsaturated fatty acids and high biological value proteins. The aim of this study was to evaluate the profile of amino acids in Brazil nut powdered milk using an HPLC system. The Brazil nut powdered milk was featured and the aminoacid profile was evaluated. The amino acids values of glutamic ...

to determine the amount of food amino acid and to spend time in the laboratories are expensive & time-consuming due to a chemical analysis. in the current laboratories, digestion nirs method is widely used for this purpose. but this method has technical limitation. therefor is important find appropriate method for estimate amount of amino acids. artificial neural network (ann) can provide a bet...
