K-Bio Matter 3: Biological Molecules 1- Carbohydrates & Lipids

There may be nothing all that special about the elements we find in living systems, but there sure is something special about the way those elements are put together. In this video (part 1 of 2), Mr. Knuffke discusses two of the four major types of biological molecules: Carbohydrates and Lipids. An introduction to their structures and functions is provided, with examples from both groups to illustrate how differences in their structures leads to differences in their functions for life.
