Acetate

is a salt formed by the combination of acetic acid with an alkaline, earthy, or metallic base. “Acetate” also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written...

Anion and Cation

– Anion (-) is an ion with more electrons than protons, giving it a net negative charge (since electrons are negatively charged and protons are positively charged). Cation (+) is an ion with fewer electrons than protons, giving it a positive...

Anions

– Hydrogen atom (center) contains a single proton and a single electron. Removal of the electron gives a cation (left), whereas addition of an electron gives an anion.  

Bacteriophage

also known informally as a phage – is a virus that infects and replicates within a bacterium. Bacteriophages are composed of proteins that encapsulate a DNA or RNA genome, and may have relatively simple or elaborate structures. Their genomes may encode as few as...

Capsids

Capsids – A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called...
