(Phys.org) —Strong, thin fibers called microfilaments, or actin filaments, are present in the cytoplasm of almost every cell in the body. By growing and shrinking, actin filaments play a major role in cellular movement. ...
(Phys.org)—In natural product and pharmaceutical chemistry, one goal is to find a modular reaction to put together complex products, similar to how amino acids combine to form a peptide. Ideally, this modular reaction could ...
Utah State University scientists have published two papers in a high profile academic journal this week that unlock mysteries of a chemical process upon which all life on earth depends.

Many of the objects we encounter are made of polymers—long chains of repeating molecules. Networks of polymers form manmade materials such as plastics, as well as natural products such as rubber and cellulose.

(PhysOrg.com) -- Diazomethane is a toxic, explosive reagent prepared as needed in laboratories, where it is commonly used in cyclopropanation, but its explosive nature prevents it being used widely on an industrial scale. ...
Actin filaments are dynamic protein-fibers in the cell built from single actin proteins. Many cellular functions, including cell movement, are regulated by constant filament assembly and disassembly. The disassembly phase ...

Hydrolysis (English pronunciation: /haɪˈdrɒlɨsɪs/, from Greek roots hydro "water" + lysis "separation") is a chemical reaction during which molecules of water (H2O) are split into hydrogen cations (H+, conventionally referred to as protons) and hydroxide anions (OH−) in the process of a chemical mechanism. It is the type of reaction that is used to break down certain polymers, especially those made by condensation polymerization. Such polymer degradation is usually catalysed by either acid, e.g., concentrated sulfuric acid (H2SO4), or alkali, e.g., sodium hydroxide (NaOH).
