The enzymatic hydrolysis of the particular quality of raw material yield natural free amino acids and low molecular weight peptides in an ideal synergetic mixture. Tests made also directly on hair have shown the excellent properties of KELYAMIN for hair care formulations. The free amino acids are capable of penetrating the hair shaft whereas the peptides with their film-forming properties compl...

The liver plays a key role in the metabolism of amino acids as it removes releases and incorporates them into different proteins and compounds. Patients with liver disease show abnormalities in the plasma amino-acid profile [1-3]. In advanced liver disease there is usually an increased concentration of the aromatic amino-acids (AAA) tyrosine, phenylalanine and tryptophan, and decreased concentr...

Amino acid, Fatty acid, Meat, Freezing. Due to the effect of cold treatment on the amino acid profile of meat has not sufficiently studied. This study aimed to study the effect of freezing temperature and duration of frozen storage on amino acid profile and fatty acid pattern in imported beef meat, local beef meat, chicken breast and Nile tilapia fish. The effect of freezing on lipid and protei...

EGL3 and RCE1 are glycoside hydrolase family 45 endoglucanases isolated from Humicola grisea and Rhizopus oryzae respectively. The amino acid sequences of the two endoglucanases are homologous; on the other hand, the optimum temperature of EGL3 is higher than that of RCE1. In this study, four chimeric endoglucanases, named ER1, ER2, ER3 and ER4, in which one of four sequential amino acid region...

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...

Quorum sensing controls the luminescence of Vibrio fischeri through the transcriptional activator LuxR and the specific autoinducer signal produced by luxI. Amino acid sequences of these two genes were analyzed using bioinformatics tools. LuxI consists of 193 amino acids and appears to contain five α-helices and six ß-sheets when analyzed by SSpro8. LuxI belongs to the autoinducer synthetase fa...

N-alkyl amino acids find widespread application as highly valuable, renewable building blocks. However, traditional synthesis methodologies to obtain these suffer from serious limitations, providing a major challenge to develop sustainable alternatives. We report the first powerful catalytic strategy for the direct N-alkylation of unprotected α-amino acids with alcohols. This method is highly s...

In lb is research, adsorption of some amino acids and their complenation with manganese (II) ion on carbonnanotube (MWCNT) by using of four relations Langmuir, Freundlich. Temkin and Harkins -Jura imitherms wasinvestigated. From this relations. Freudlich and Temkin relations predict good equilibrium diagram in, isothermcondition. we could compute the theoretical constants by excel software. Hy ...

it has been reported that neurons in the vl pag projecting to nucleus raphe magnus (nrm) utilize excitatory amino acids as neurotransmitter. this projection plays an important role in the descending pain modulatory system. in order to determine the role of this pathway in pain perception, male rats received unilateral injection of ibotenic acid stereotaxically. for lesioning vl pag, unilateral ...

the adsorption of a number of amino acids on a defected single-walled carbon nanotube (swcnt) isinvestigated by using the density-functional theory (dft) calculations. the adsorption energies andequilibrium distances are calculated for various configurations such as amino acid attaching to defectsites heptagon, pentagon and hexagon in defective tube and also for several molecular orientationswi...
