Has a fatty acid in the form of a tail, glycerol head, and a phosphate group. Phospholipids behave uniquely in an aqueous environment they are said to be amphipathic meaning that they have both a hydrophilic head water loving which interacts within the aqueous environment of the cell membrane and a hydrophobic tail water fearing which interacts with the interior of the cell membrane away from the aqueous environment.

Phospholipids

Fatty acids are lipids that contain long-chain hydrocarbons that end with a carboxylic acid functional group. Fatty acids tend to have a nonpolar or hydrophobic chain.

Fatty Acids

A lipid that is formed withthree fatty acids are chemically linked to a glycerol molecule. This type of lipid plays a key factor in being energy storage molecules.

Triacylglycerides (triacylglycerol)

These are branched lipids formed by chemical modifications of the isoprene molecule. They are widely used in pharmaceuticals, pigments, fragreces, waxes, and oils.

Isoprenoids (terpenoids)

Steriods are complex ringed structures that are found within the cell membrane and some function as hormones.

Steroid

There are different types of lipids which include:

- Fatty Acids 
- Triacylglycerides
- Isoprenoids 
- Sterols
- Phospholipids

Lipids are macromolecules that are composed of carbon, hydrogen, and oxygen.  Lipids are typically hydrophobic, nonpolar, and composed of hydrocarbon chains.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
