Types of Structure
What is the primary structure of proteins?
True or false: Proteins are small, but complex molecules
False: proteins are LARGE and complex molecules
True or false: the shape of proteins determines the function
True: the structure of proteins dictates their job!
True or false: globular proteins are more linear than fibrous proteins.
False - it is the opposite!
When you change the shape of a protein without breaking the bonds, what is this process called?
Denaturation
What is the secondary structure of proteins?
Helix
What elements make up proteins? Hint: there are 4 major ones.
Carbon, hydrogen, oxygen, and nitrogen
What do proteins and carbohydrates have in common relating to structure?
They both are important in the structure of the cell wall.
What is the function of fibrous proteins?
Provide structure and strength
When a protein is broken down, and then reaggregates, what is this process called?
Coagulation
What is the tertiary structure of proteins?
Polypeptide chains
What part of the composition of proteins gives them their versatililty?
Nitrogen
What are the two types of proteins?
Fibrous and globular
What is the function of globular proteins?
Many roles, but important in transportation/carrier molecules.
What is the most common form of denaturation?
Denaturation by heat
2+ polypeptides
Polypeptides are linked with what kind of bonds?
Collagen and elastin are two examples of which kind of protein?
Fibrous
What kind of protein is meat?
Fibrous
What is found in the hides and bones of animals to make gelatin?
Collagen
How many alpha amino acids exist?
22
Peptide bonds are between what two elements?
Carbon and nitrogen
Hemoglobin is an example of which kind of protein?
Globular
How is the structure of fish different from meat?
Fish have minimal connective tissue and segmented muscle fibres, making it more flaky!
How is meringue formed?
Meringue is formed by beating eggs whites and incorporating air bubbles. As you beat the egg whites, they are denatured, and this allows them to form a protein film around the air bubbles, keeping the meringue fluffy and light!
