What three components make up the structure of a fatty acid?

Fatty acids are constructed from the chemical elements carbon, oxygen and hydrogen. Fatty acids can be divided into a carboxylic acid head group–hence fatty acid–linked to a long chain of carbon atoms.

What is the structure and function of fatty acids?

Function of Fatty Acids. Fatty acids have important roles in: 1) signal-transduction pathways; 2) cellular fuel sources; 3) the composition of hormones and lipids; 4) the modification of proteins; and 5) energy storage within adipose tissue (specialized fat cells) in the form of triacylglycerols.

What are the properties of fatty acids?

Physical Properties:

  • Fats and fatty acids are soluble in organic solvents, such as petroleum ether, benzene and chloroform.
  • Saturated fatty acids are solid at room temperature, while unsaturated fatty acids are liquid.
  • Unsaturated fatty acids show cis-trans isomerism due to presence of double bonds.

What are the main differences in various fatty acids?

Fatty acids differ from each other in the number of C atoms, from 12-C to 24-C, and in the number of double bonds in the chain, from none to one, two, or three. Seed oils in different species vary widely in the proportion of different fatty acids, although 18-C unsaturated fatty acids generally predominate.

What are the three main types of fatty acids?

There are three main types of fatty acids: saturated, monounsaturated and polyunsaturated. All fatty acids are chains of carbon atoms with hydrogen atoms attached to the carbon atoms.

What do all fatty acids have in common?

The most common fatty acids contain 12–22 carbon atoms. Monounsaturated fatty acids have one carbon–carbon double bond, which can occur in different positions. The most common monoenes have a chain length of 16–22 and a double bond with the cis configuration.

What are the worst fats?

The worst type of dietary fat is the kind known as trans fat. It is a byproduct of a process called hydrogenation that is used to turn healthy oils into solids and to prevent them from becoming rancid. Trans fats have no known health benefits and that there is no safe level of consumption.
