First, the syllabus guide:
1 From: Biology for the IB Diploma 2nd Edition, c.J.Clegg, 2014, Hodder Education
This is the Core material
2 From: Biology in Context for Cambridge International A Level, Glenn and Susan Toole, Nelson Thornes, 2013
Very thorough and readable but be careful – quite much is HL!
AMINO ACID STRUCTURE
You do not need to remember the different amino acids, but it is useful to see the common structure.
THE PEPTIDE BETWEEN TWO AMINO ACIDS (which you have to be able to draw)
CHROMATOGRAPHY FOR AMINO ACIDS
This is a quite sophisticated lab, needing proper chromatography equipment and also ninhydrin to stain up the amino acids. As the amino acids stain up and show on the chromatography paper, you can expect a “Eureka!” moment!
