Cholesterol is a component of the phospholipid bilayer and plays a role in the structure and function of membranes. Steroids are found in the brain and alter electrical activity in the brain.

3.6: Lipids

Fats are actually a type of lipid. Lipids are a major class of biochemical compounds that includes oils as well as fats. Organisms use lipids to store energy and for many other uses. Lipid molecules consist mainly of repeating units called fatty acids. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids.

Anabolic steroid

OverviewUsesAdverse effectsPharmacologyChemistryHistorySociety and cultureResearch

Anabolic steroids, also known as anabolic-androgenic steroids (AAS), are a class of drugs that are structurally related to testosterone, the main male sex hormone, and produce effects by binding to the androgen receptor. Anabolic steroids have a number of medical uses, but are also used by athletes to increase muscle size, strength, and performance.

2.3: Biological Molecules

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell''s mass. Biological macromolecules are organic, meaning that they contain carbon (with ...
