To ensure that you understand the material in this chapter, you should review the meanings of the bold terms in the following summary and ask yourself how they relate to the topics in the chapter. Lipids , found in the body tissues of all organisms, are compounds that are more soluble in organic solvents than in water. Many of them contain fatty acids , which are carboxylic acids that generally contain an even number of 4—20 carbon atoms in an unbranched chain.
The lipids are a large and diverse group of naturally occurring organic compounds that are related by their solubility in nonpolar organic solvents e. There is great structural variety among the lipids, as will be demonstrated in the following sections. You may click on a topic listed below, or proceed page by page. 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. These long-chain carboxylic acids are generally referred to by their common names, which in most cases reflect their sources. Natural fatty acids may be saturated or unsaturated, and as the following data indicate, the saturated acids have higher melting points than unsaturated acids of corresponding size.

It has developed from earlier publications by the author and from his experience over 50 years in reading, writing, thinking, and working with lipids and fatty acids.

Fatty acids are basic chemical units of fat, and the names and structural features of several are shown in Table The fatty acids most commonly found in primates and in primate diets have 16 and 18 carbon atoms; those found less commonly have 12, 14, 20, and 22 carbon atoms.

In chemistry , particularly in biochemistry , a fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to In any of these forms, fatty acids are both important dietary sources of fuel for animals and they are important structural components for cells.
The lipids are a large and diverse group of naturally occurring organic compounds that are related by their solubility in nonpolar organic solvents e. There is great structural variety among the lipids, as will be demonstrated in the following sections. Compounds isolated from body tissues are classified as lipids if they are more soluble in organic solvents, such as dichloromethane, than in water. They may be saturated or unsaturated.
