What are the two categories of fatty acids?

Question

Quizplus · Accepted Answer

There are two categories of fatty acids: saturated and unsaturated fats.
Saturated fats contain no double bonds in their hydrocarbon tail. As a result, saturated fats are solid at room temperature and are considered detrimental to your health.
Unsaturated fats contain one or more double bonds in their hydrocarbon tail. As a result, unsaturated fats are liquid at room temperature.
Phospholipids are a type of lipid. They consist of two fatty acids bonded to a phosphate group. The phosphate group is polar and soluble in water whereas the hydrocarbon tail of the fatty acids is nonpolar and non-soluble in water. This quality is important in the function of cellular membranes, including the plasma membrane, as the molecules organize themselves in a way that creates a barrier to protect the cell.
Steroids are a type of lipid but are not a fatty acid. They are a component of membranes and an essential part of many hormones and drugs.
Enzymes are a type of protein. They catalyze (cause or accelerate) different reactions and processes. Almost all cellular function is catalyzed by some type of enzyme.
