Investigating Protein Structure

Investigating Protein Structure

Unit 3 Applied Science. 

Learning Objective

• Understand the structure of proteins
• Learn about the composition and function of amino acids
• Understand how peptide links join amino acid residues
• Learn about the structure and function of enzymes

What do you already know about proteins and their structure?

Proteins and their Structure

• Proteins are composed of amino acid residues connected by peptide links
• Enzymes are a type of protein molecule

Amino Acids and Protein Structure

• Amino acids have an amino group and a carboxyl group attached to a central carbon atom
• Amino acids play a role in protein structure

Peptide Links in Protein Formation

• Peptide links are covalent chemical bonds formed between two amino acid molecules
• Peptide links join amino acid residues in proteins

Enzymes as Protein Molecules

• Enzymes are a type of protein molecule
• Understanding protein structure helps comprehend enzyme function

Definition List

• Peptide link: a functional group consisting of covalent chemical bonds formed between two amino acid molecules (CO-NH-)
• Alpha amino acid: a compound that contains a carboxyl group (COOH) and an amino group (NH₂) attached to a central carbon atom

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
