B0007705 Amino acid: Tyrosine by wellcome images on flickr

  • Can you distinguish between organic and inorganic compounds?
  • Can you identify carbohydrates, lipids and proteins from diagrams?
  • Can you explain the role of condensation and hydrolysis reactions between amino acids and polypeptides, between mono, di and polysaccharides, and between fatty acids, glycerol and triglycerides?
  • Can you compare the use of carbohydrates and lipids in energy storage?

If you can answer yes to all of the above questions, you are ready to move on….

In this section we’ll use this great presentation, and we’ll also be doing a lab. Lab – Comparison of chemical composition of food

Then we’ll need to venture into our first bit of higher level material on protein structure.  This may also be useful: Proteins AHL

Do you know the structure of glucose, amino acids and triglycerides

Can you draw these molecules? 

Do you know what carbohydrates, proteins and lipids are used for in living organisms? 

By the end of the week, the answer should be YES to each of these questions.  If not – come and ask for help in tutorials.
