apigenin is best known as an irreversible inhibitor of monoamine oxidase (mao), an intracellular enzyme associated with the outer membrane of mitochondria. the purpose of this study is to establish a reliable and quick method for the assignment of apigenin in cosmos bipinnatus, apium graveolens and petroselinum crispum by high performance liquid chromatography with ultraviolet detection (hplc-u...

We study a simple heteropolymer model containing sequence-independent local interactions on both square and triangular lattices. Sticking to a two-letter code, we investigate the model for varying strength of the local interactions; = 0 corresponds to the well-known HP model K.F. Lau and K.A. Dill, Macromolecules 22, 3986 (1989)]. By exhaustive enumerations for short chains, we obtain all struc...

La parte experimental consistió colectar preparar reactivo DNS elaborar curva cali...

We study the conformational properties of heteropolymers containing two types of monomers A and B, modeled as self-attracting self-avoiding random walks on a regular lattice. Such a model can describe in particular the sequences of hydrophobic and hydrophilic residues in proteins [K. F. Lau and K. A. Dill, Macromolecules 22, 3986 (1989)] and polyampholytes with oppositely charged groups [Y. Kan...
