Steroids have four rings arranged in a specific configuration and are classified into three types of hormones. Ultraviolet absorption spectroscopy analyzes electronic transitions that occur when organic compounds absorb UV radiation. Chromophores and auxochromes determine a molecule's ability to absorb light at specific wavelengths. Interpretation of cholesterol's UV spectrum showed absorption peaks corresponding to carbon-carbon double bonds. Infrared spectroscopy identified functional groups in cholesterol through peaks attributed to O-H, C=H, C-H, and C=O bonds. Nuclear magnetic resonance spectroscopy and mass spectrometry further analyzed cholesterol's molecular structure.
