12th CBSE - Biomolecules
- 2. To discuss classification of amino acids To interpret structure of proteins To explain denaturation of proteins Learning Outcomes
- 3. What are proteins? Biomolecules Proteins are polymers of smaller subunits called the amino acids.
- 4. What is the general formula of amino acids? Biomolecules Amino acids contain amino (–NH2) and carboxyl (–COOH) functional groups. Depending upon the relative position of amino group with respect to carboxyl group, the amino acids can be classified as α, β, γ, δ and so on. Only α-amino acids are obtained on hydrolysis of proteins.

- 6. How are amino acids classified? Biomolecules
- 7. What are Zwitter ions? Biomolecules
- 8. What do we know about amino acids? Biomolecules All amino acids, except glycine, are optically active. Most naturally occurring amino acids have L-configuration.

- 18. What is denaturation of proteins? Biomolecules When a protein in its native form, is subjected to physical change like change in temperature or chemical change like change in pH, the hydrogen bonds are disturbed. Due to this, globules unfold and helix get uncoiled and protein loses its biological activity and is called denaturation.
- 19. What is denaturation of proteins? Biomolecules The reverse process is called as renaturation of proteins.

Editor's Notes
- An overview of the content of the lesson Must be in the form of a question where appropriate Students should be able to answer the question at the end - either fully, partly or in a way that demonstrates they understand what gaps in their knowledge they need to address Verbs such as to understand / to know / to gain confidence / to learn Ask students to give the question a go and point out that, at the end of the lesson, they should be able to answer fully
- Measurable outcomes that students can demonstrate and self-assess against Must be written using Bloom’s taxonomy verbs Verbs based on students ability and pitch of lesson It must be clear that students understand the outcomes before moving on Make an activity of this slide: Ask students to read this aloud Ask them to paraphrase Ask that they explain what they mean Ask what they already know related to these outcomes There may be as few as 2 outcomes, or max 4
- The next slides should be focused on achieving first outcome Make reference to the outcome in the teaching Fill this with thinking skills activities, peer assessment, higher-order questioning, engaging activities and challenge

- Revisit the first outcome and use the polling function to allow students to privately self-assess You may feel that the students do not need privacy to self-assess and in this instance, the chat box may be used Polling must be used until you can fully assess their confidence to use the chat box and express honesty If students self-assess as a 4/5, ensure that you are fully confident in their assessment Ask questions Ask for examples Students to ask each other questions If a few students self-assesses as a 3, but others as a 4/5, discretely ask the higher ones to give examples and to explain their achievement/understanding If all students are a 3 or below, do not move on. Move to a blank page at the end of the presentation and use as a whiteboard to further explain If students are ½, go back to the beginning Always ask students what the gaps are and help them to identify these in order to promote metacognition
- 1. The outcome changes colour when achieved to the same colour as the objective to demonstrate the connection, progress and what happens next
