Protonation behavior of dextran amino acid esters

Protonation constants of amino acid salts at 298-353 K

Since there is no flue-gas desulfurization facility (FGD) in Australian Power Plants, the temperatures of flue gases from the plants range from 393–433 K which is much higher than the absorption temperatures in a typical post combustion CO2 capture (PCC) process. The additional cooling systems and equipments are required to cool flue gases. This adds to the cost, and water and energy consumptio...

Crystallization Behavior of Fatty Acid Methyl Esters

Biodiesel from most agricultural feedstocks has flow properties that are prone to startup and operability problems during cold weather. Biodiesel from soybean oil is generally a mixture of long-chain fatty acid alkyl esters composed of 0.15–0.20 mass fraction saturated esters (melting point [MP] 0 C) mixed with unsaturated esters (MP \ 0 C). This work investigates the crystallization properties...

A convenient synthesis of amino acid methyl esters.

A series of amino acid methyl ester hydrochlorides were prepared in good to excellent yields by the room temperature reaction of amino acids with methanol in the presence of trimethylchlorosilane. This method is not only compatible with natural amino acids, but also with other aromatic and aliphatic amino acids.

The pH Dependence of Protonation States of Polar Amino Acid Residues Determined by Neutron Diffraction

Amino acid derivatives. Part I. Synthesis, antiviral and antitumor evaluation of new alpha-amino acid esters bearing coumarin side chain.

A series of amino acid esters bearing coumarin (3-15) were synthesized and evaluated, in vitro, against HIV-1, and bovine viral diarrhea virus (BVDV). The in vitro cytotoxicity of 3-10 and 12 was assayed against a panel of tumor cell lines consisting of CD4 human T-cells. Compound 14 showed inhibition of HIV-1 with EC50 > 1.6 microg mL(-1), meanwhile compound 9 exhibited activity against leukae...
