                                Steroids are organic compounds that are hydrophobic and insoluble in water, despite having a structure that differs from other lipids. They are defined by a characteristic core structure, known as the steroid nucleus or gonane. Thousands of different steroid molecules found in nature share this fundamental architecture.
