Saturation, saturated, unsaturation or unsaturated may refer to:

Chemistry

* Saturated and unsaturated compounds, a classification of compounds related to their ability to resist addition reactions ** Degree of unsaturation ** Saturated fat or saturated fatty acid ** Unsaturated fat or unsaturated fatty acid ** Non-susceptibility of an organometallic compound to oxidative addition * Saturation of protein binding sites * Saturation of enzymes with a substrate * Saturation of a solute in a solution, as related to the solute's maximum solubility at equilibrium ** Supersaturation, where the concentration of a solute exceeds its maximum solubility at equilibrium ** Undersaturation, where the concentration of a solute is less than its maximum solubility at equilibrium

Biology

Saturation (magnetic) Seen in some magnetism, magnetic materials, saturation is the state reached when an increase in applied external magnetic field ''H'' cannot increase the magnetization of the material further, so the total magnetic flux density ''B'' more or less ...

, the state when a magnetic material is fully magnetized * Saturated fluid or saturated vapor, contains as much thermal energy as it can without boiling or condensing ** Saturated steam * Dew point, which is a temperature that occurs when atmospheric relative humidity reaches 100% and the air is saturated with moisture * Saturated absorption, a set-up that enables the precise determination of the transition frequency of an atom between its ground state and an optically excited state

Electronics
