Learning Outcomes
• Analyze and distinguish among triglyceride,
phospholipids, fats, and steroids, and describe
the structural composition, characteristics, and
biological functions of each.
• Explain the meaning of the terms primary

Overview: Carbon: The Backbone of
Life
• Although cells are 70–95% water, the rest
consists mostly of carbon-based compounds
• Carbon is unparalleled in...
