Proteins (OCR A-level Biology)

According to Bill Bryson’s book, “THE BODY”, estimates of the number of proteins in the human body range from a few hundred thousand to a million or more. Regardless of whether the actual number is closer to the bottom or the top estimate, as most of the useful things in the body are proteins, it is clear that a deep understanding of the structure and function of this biological molecule is critical for the success of any student on the OCR A-level Biology A course. All 5 of the lessons included in this bundle are highly detailed and contain a wide range of tasks that will engage and motivate the students whilst ensuring that the specification points in module 2.1.2 regarding proteins are covered.

The following content is covered by the lessons in this bundle:

• The general structure of an amino acid
• The synthesis and breakdown of dipeptides and polypeptides, by the formation and breakage of peptide bonds
• The levels of proteins structure
• The structure and function of globular proteins
• The properties and functions of fibrous proteins
• The biuret test for proteins

The 5th lesson is a revision lesson which uses a range of exam-style questions, understanding checks and quiz competitions to check on the students knowledge of the specification details listed above
