Alkanes are found in animal products, although they are less important than unsaturated hydrocarbons. One example is the shark liver oil, which is approximately 14% pristane (2,6,10,14-tetramethylpentadecane, C 19 H 40). They are important as pheromones, chemical messenger materials, on which insects depend for communication.
They include higher alkanes and lipids, typically with melting points above about 40 °C (104 °F), melting to give low viscosity liquids. Waxes are insoluble in water but soluble in nonpolar organic solvents such as hexane, benzene and chloroform. Natural waxes of different types are produced by plants and animals and occur in petroleum.
For example, a certain sequence on the genome codes for the degradation of a certain range of alkanes. The A. borkumensis genome has many sequences that each code for a different type of alkane, allowing it to be highly adaptable and versatile. Its genome also contains instructions for the formation of biosurfactants which aid in the process of ...
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs.
The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1 ] [ 2 ] Number of C atoms
An alkane is an acyclic saturated hydrocarbon. See Alkane. Alkanes as substituents are called alkyl groups Subcategories. This category has the following 5 ...
An example is the members of Methanosaeta genus dominate the digestion of palm oil mill effluent (POME) and brewery waste. [54] Modernizing wastewater treatment systems to incorporate higher diversity of microorganisms to decrease organic content in treatment is under active research in the field of microbiological and chemical engineering.

For example, the abdominal glands of the female silkmoth release traces of the (E,E)-isomer of alcohol as well as the analogous (E,Z)-aldehyde bombycal, in addition to the sex pheromone bombycol. [ 33 ] [ 34 ] Suitable surface geometries in the vicinity of the glands, such as grooved pore plates, may favor effective evaporation of a leaked ...
