addition of potassium cyanide to a mixture of schiff base and lithium perchlorate afforded a-aminonitriles in high yields. addition of potassium cyanide to a methanolic solution of schiff base and phosphoric acid afforded a-aminonitriles. when the reaction mixture was refluxed it gave a-amino acids in high yields.
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...

In order to study the tendency of amino acid neighbors in helical structures, proteins with known structures were carefully analyzed. The studied helical positions: N , Ncap, N1, N2, N3, N4, M, C4, C3, C2, C1, Ccap, C and their doublet counterparts: N Ncap, NcapN1, N1N2, N2N3, N3N4, M1M2, M2M3, C4C3, C3C2, C2C1, C1Ccap, CcapC were carefully analyzed. The propensity for all amino acids i...
