Lab 1 - Chemical Composition of Cells
Please follow these four steps:
Go to Step: 1 | 2 | 3 | 4

Step One
Lab One is about "Chemistry"! Everything in the human body can be broken down to simple chemicals like proteins, carbohydrates (sugars), lipids (fats) and nucleic acids (DNA). Even these molecules can be broken down to a relatively few important elements (atoms) like carbon (C), hydrogen (H), nitrogen (N), oxygen (O), phosphorus (P) and sulfer (S). 98% of your body consists of these six simple elements.

Please work your way through the following four steps for this online lab.

When you have completed the Pre-Lab Lectures you are ready to move onto Step Two, Lab Activity.

Pre-Lab Lecture

Objective
To understand basic atomic structure and the chemical properties of water, the structure and primary functions of carbohydrates, lipids, proteins and nucleic acids in cells.

Step Two
This BioCoach activity will help you review molecular formulas and models, major elements and their valences, and the important functional groups of biological molecules. It will also let you try your hand at building certain molecular models.

Please go to the following links to get all the instructions for doing your experiments.
