This article covers protein engineering [1] of cytochrome (CYP) P450 enzymes.P450s are involved in a range of biochemical catabolic and anabolic process. [2] Natural P450s can perform several different types of chemical reactions including hydroxylations, N,O,S-dealkylations, epoxidations, sulfoxidations, aryl-aryl couplings, ring contractions and expansions, oxidative cyclizations, alcohol ...
Surface area plays a very important role in drug delivery and per mg of gold, as diameters decrease, the surface areas needed to transport drugs increase to the point where a single 1mL volume of 1.8 nm spherical gold nanoparticles have the same surface area as a cell phone.
The chemical reaction for the dissolution of gold, the "Elsner equation", follows: 4 Au + 8 NaCN + O 2 + 2 H 2 O → 4 Na[Au(CN) 2] + 4 NaOH. Potassium cyanide and calcium cyanide are sometimes used in place of sodium cyanide. Gold is one of the few metals that dissolves in the presence of cyanide ions and oxygen.

Gold pentafluoride, along with its derivative anion, AuF − 6, and its difluorine complex, gold heptafluoride, is the sole example of gold(V), the highest verified oxidation state. [ 19 ] Some gold compounds exhibit aurophilic bonding , which describes the tendency of gold ions to interact at distances that are too long to be a conventional Au ...

In engineering and physics, g c is a unit conversion factor used to convert mass to force or vice versa. [1] It is defined as = In unit systems where force is a derived unit, like in SI units, g c is equal to 1.
