Polyenes are poly-unsaturated organic compounds that contain one or more sequences of alternating double and single carbon-carbon bonds. In Chemistry, saturation has five different meanings In Physical chemistry, saturation is the point at which a Solution of a substance An organic compound is any member of a large class of Chemical compounds whose Molecules contain Carbon. Carbon (kɑɹbən is a Chemical element with the symbol C and its Atomic number is 6 These double carbon-carbon bonds interact in a process known as conjugation, which results in an overall lower energy state of the molecule. A chemically conjugated system is a system of atoms Covalently bonded with alternating single and multiple (e

Organic compounds with two carbon-carbon double bonds are dienes; those with three such double bonds are trienes; those with four are tetraenes, etc. Dienes or diolefins are Hydrocarbons which contain two double bonds.

Amphotericin B is an example of a yellow-colored polyene antimycotic agent. Amphotericin B (Fungilin Fungizone Abelcet AmBisome Fungisome Amphocil Amphotec is a Polyene Antifungal drug, often used Intravenously Polyene antimycotics, sometimes referred to as polyene antibiotics, are a class of Antimicrobial Polyene compounds that target Fungi Note the alternating double and single bonds in the center.

Normally carbon-carbon double bonds which are not conjugated or only conjugated with only one or two other carbon-carbon double bonds have high enough energy that they absorb in the ultraviolet region of a spectrum, but the absorption energy state of polyenes with numerous conjugated double bonds can be lowered such that they enter the visible region of the spectrum, resulting in compounds which are colored yellow or other colors. Ultraviolet ( UV) light is Electromagnetic radiation with a Wavelength shorter than that of Visible light, but longer than X-rays Ultraviolet-visible spectroscopy or ultraviolet-visible spectrophotometry ( UV/ VIS) involves the Spectroscopy of Photons in the UV-visible

Many fatty acids are polyenes, and many dyes contain linear polyenes. In Chemistry, especially Biochemistry, a fatty acid is a Carboxylic acid often with a long unbranched Aliphatic tail ( chain) which A dye can generally be described as a Colored substance that has an affinity to the substrate to which it is being applied Other examples of polyene compounds include beta-carotene, which is yellow to orange colored depending on concentration, and polyene antimycotics, some of which are yellow colored. Beta-carotene is an Organic compound - a Terpenoid, a red-orange pigment abundant in plants and fruits Polyene antimycotics, sometimes referred to as polyene antibiotics, are a class of Antimicrobial Polyene compounds that target Fungi
