L-alanine and its peptides (L-Ala-2-6) do not attract or repulse Tetrahymena in a 10(-8) M concentration. In 10(-10) M concentration there is a consistent repellent effect. Twenty four hours after L-alanine or L-alanine-peptides' pretreatment (imprinting) the progeny generation of the cells react differently to the same materials. L-Alanine, L-alanine penta- and hexapeptide in both concentratio...

Herein, we described novel biogenic preparation of the CuO nanorods and its surface modification with l-alanine amino acid accelerated by microwave irradiation. The effect functionalized on physico-mechanical properties polyvinyl alcohol/carboxymethyl cellulose films were investigated through various characterization techniques. tensile strength was improved from 28.58 ± 0.73 to 43.40 0.93 MPa,...

Twist states of Bacillus subtilis macrofibers were found to vary as a function of the concentration of D-alanine in the medium during growth. L-Alanine in the same concentration range had no effect. Increasing concentrations of D-alanine resulted in structures progressively more right-handed (or less left-handed). All strains examined in this study, including mutants fixed in the left-hand doma...

A proton motive force (delta p) generated by oxidation of CO in membrane vesicles of Clostridium thermoautotrophicum drove active transport of L-alanine, glycine and L-serine. The maximum rate (Vmax) for L-alanine transport was 12 X higher at 50 degrees C than at 25 degrees C. The apparent transport constant (Kt) for L-alanine uptake was 30-40 microM and independent of the temperature. Glycine ...

Flies recycle the photoreceptor neurotransmitter histamine by conjugating it to β-alanine to form β-alanyl-histamine (carcinine). The conjugation is regulated by Ebony, while Tan hydrolyses carcinine, releasing histamine and β-alanine. In Drosophila, β-alanine synthesis occurs either from uracil or from the decarboxylation of aspartate but detailed roles for the enzymes responsible remain uncle...

β-alanine is an amino acid that, when combined with histidine, forms the dipeptide carnosine within skeletal muscle. Carnosine and β-alanine each have multiple purposes within the human body; this review focuses on their roles as ergogenic aids to exercise performance and suggests how to best quantify the former's merits as a buffer. Carnosine normally makes a small contribution to a cell's tot...
