Fats, Oils, Waxes & Phospholipids 1. Fatty Acids. The common feature of these lipids is that they are all esters of moderate to long chain fatty acids. Acid or base-catalyzed hydrolysis yields the component fatty acid, some examples of which are given in the following table, together with the alcohol component of the lipid.

Lipids, as a class of compounds, are insoluble in water but are soluble in other organic solvents.Examples of such solvents include acetone and ether. Waxes, steroids, phospholipids, and fats are the most common types of lipid groups. Fats have glycerol in addition to three fatty acids. The structure of the fatty acids determines whether or not the fat is considered saturated or unsaturated.

Waxes are esters of fatty acids with long chain monohydric alcohols (one hydroxyl group). Natural waxes are often mixtures of such esters, and may also contain hydrocarbons. The formulas for three well known waxes are given below, with the carboxylic acid moiety colored red and the alcohol colored blue.
Get Price19.10.2015· Waxes and Oils are lipids, having hydrophobic properties, and are derived from plants and animals. Oil is simply fat with unsaturated fatty acid chains, and is found in liquid form at room temperature. Waxes are very much like fats or oil, except that they are malleable in normal conditions, and have only single long-chain fatty acid, attached to a long-chain alcohol group.

Long-chain isoprenoids are also found in hydrophobic oils and waxes. Waxes are typically water resistant and hard at room temperature, but they soften when heated and liquefy if warmed adequately. In humans, the main wax production occurs within the sebaceous glands of hair follicles in the skin, resulting in a secreted material called sebum

Waxes, esters of fatty acids with fatty alcohols, found in olive oil are esters C36, C38, C40, C42, C44, and C46. As they accumulate in the skin of olives, higher amounts of them can be detected in olive pomace oils rather than in olive oils ( Bianchi et al., 1994 ).

Fatty acid metabolism is an attractive route to produce liquid transportation fuels and commodity oleochemicals from renewable feedstocks. Recently, genes and enzymes, which comprise metabolic pathways for producing fatty acid-derived compounds (e.g. esters, alkanes, olefins, ketones, alcohols, polyesters) have been elucidated and used in engineered microbial hosts.
