애플리케이션

Magnesium sulfate heptahydrate can be used as a catalyst to synthesize tri/tetra-substituted imidazoles via a one-pot condensation reaction of aromatic aldehydes, benzil, aliphatic and aromatic primary amines, and ammonium acetate. It is also used to synthesize phenazine and quinoxaline derivatives.

Most bacterial species encompass strains with vastly different gene content. Strain diversity in microbial communities is therefore considered to be of functional importance. Yet little is known about the extent to which related microbial communities differ in diversity at this

Cell polarity is a key feature in the development of multicellular organisms. For instance, asymmetrically localized plasma-membrane-integral PIN-FORMED (PIN) proteins direct transcellular fluxes of the phytohormone auxin that govern plant development. Fine-tuned auxin flux is important for root protophloem sieve
