Overview:
Another level in the hierarchy of biological organization is reached when small organic molecules are joined together
Atom ---> molecule ---? compound
*
Macromolecules
Are large molecules composed of smaller molecules
Are complex in their structures

Carbon Chemistry
Carbon is the Backbone of Biological Molecules (macromolecules)
All living organisms Are made up of chemicals based mostly on the element carbon

The Structure and Function of Macromolecules
Biological Molecules
The study of carbon compounds, organic chemistry, focuses on any compound with carbon (organic compounds)
Proteins, DNA, carbohydrates, and other molecules that distinguish living matter from inorganic material are all composed of carbon atoms bonded to each other and to atoms of other elements
Chapter 2
The Chemical Context of Life
Basic Terms
Element = cannot be broken down to other substances
Examples: Na, O, C, Cl
Compound = combination of 2 or more different elements
Examples: NaCl, CO2, CH4
Requirements for Life
92 natural elements?
25 are essential to life
Carbon, oxygen, hydrogen, and nitrogen make up 96% of living matter
Trace elements are needed, too, though
