This detailed lesson describes the different levels of protein structure and focuses on the bonds that hold these molecules in shape. Both the engaging PowerPoint and accompanying resources have been designed to cover specification point 2.3 (b) of the CIE International A-level Biology course and makes continual links to previous lessons such as amino acids & peptide bonds as well as to upcoming lessons like enzymes and antibodies.
The start of the lesson focuses on the formation of a peptide bond during a condensation reaction so that students can understand how a dipeptide is formed and therefore how a polypeptide forms when multiple reactions occur.
The main part of the lesson describes the different levels of protein structure. A step by step guide is used to demonstrate how the sequences of bases in a gene acts as a template to form a sequence of codons on a mRNA strand and how this is translated into a particular sequence of amino acids known as the primary structure. The students are then challenged to apply their understanding of this process by using three more gene sequences to work out three primary structures and recognise how different genes lead to different sequences. Moving forwards, students will learn how the order of amino acids in the primary structure determines the shape of the protein molecule, through its secondary, tertiary and quaternary structure and time is taken to consider the details of each of these. There is a particular focus on the different bonds that hold the 3D shape firmly in place and a quick quiz round then introduces the importance of this shape as exemplified by enzymes, antibodies and hormones. Students will see the differences between globular and fibrous protein and again biological examples are used to increase relevance. The lesson concludes with one final quiz round called STRUC by NUMBERS where the students have to use their understanding of the protein structures to calculate a numerical answer.

Topics 1 & 2: Cell structure & Biological molecules (CIE A-level Biology)
It's no coincidence that cell structure and biological molecules find themselves as topics 1 and 2 of the CIE A-level Biology course, because a clear understanding of their content is absolutely critical to promote success with the 17 topics that follow. Hours and hours of intricate planning has gone into the 18 lessons included in this bundle to ensure that the detailed content is relevant and can be understood and that links are made to related sections of topics 3 - 19. The lesson PowerPoints and accompanying resources contain a wide range of activities that include: * differentiated exam-style questions with clear mark schemes * directed discussion points * quiz competitions to introduce key terms and values * current understanding and prior knowledge checks Due to the detail included in these lessons, it is estimated that it will take in excess of 2 months of allocated teaching time to cover the content of the resources A number of the resources have been shared for free so these can be downloaded in order to sample the quality of the lessons

Topic 2: Biological molecules (CIE International A-level Biology)
The biological molecules topic is incredibly important, not just because it is found near to the start of the course, but also because of its detailed content which must be well understood to promote success with the other 18 CIE International A-level Biology topics. Many hours of intricate planning have gone into the design of all of the 11 lessons that are included in this bundle to ensure that the content is covered in detail, understanding is constantly checked and misconceptions addressed and that engagement is high. This is achieved through the wide variety of tasks in the PowerPoints and accompanying worksheets which include exam-style questions with clear answers, discussion points, differentiated tasks and quick quiz competitions. The following specification points are covered by the lessons within this bundle: * Tests for reducing and non-reducing sugars * The iodine test for starch * The emulsion test for lipids * The biuret test for proteins * The ring forms of alpha and beta glucose * The meaning of the terms monomer, polymer, macromolecule, monosaccharide, disaccharide and polysaccharide * The formation of a glycosidic bond by a condensation reaction * The breakage of glycosidic bonds by hydrolysis reactions * The relationship between the molecular structure and functions of a triglyceride * The relationship between the structure and functions of a phospholipid * The structure of an amino acid and the formation and breakage of a peptide bond * The meaning of the different protein structures and the types of bonding that hold these molecules in shape * The molecular structure of haemoglobin and collagen as examples of globular and fibrous proteins * The relationship between the properties and roles of water in living organisms The lesson on the biuret test for proteins and the emulsion test for lipids also contains a section which can be used for the revision of topics 2.2 and 2.3 Due to the detail of each of these lessons, it is estimated that it will take in excess of 4 weeks of allocated teaching time to cover the content.

Topic 2.3: Proteins and water (CIE A-level Biology)
This bundle contains 4 detailed and engaging lessons that cover the content in topic 2.3 of the CIE International A-level Biology course. Due to the importance of proteins and water in living organisms, this mini-topic is fundamental to the whole course and planning has taken account of this with extra time given to key details that must be understood. The PowerPoints and accompanying resources contain a wide range of activities which include discussion points, current understanding and prior knowledge checks and quiz competitions. The following specification points are covered in this bundle: * The structure of an amino acid and the formation and breakage of a peptide bond * The meanings of primary, secondary, tertiary and quaternary structure * The types of bonding that hold protein molecules in shape * The molecular structure of haemoglobin as an example of a globular protein * Collagen as an example of a fibrous protein * The relationship between the properties of water and its roles in living organisms If you would like to sample the quality of the lessons, download the haemoglobin and collagen lesson as this has been shared for free
