What are the four main types of proteins mentioned in the notes?

Enzymatic proteins, hormonal proteins, motor proteins, and defensive proteins.

What role do enzymatic proteins play?

They act as catalysts to speed up biochemical reactions.

What is an example of a hormonal protein?

Insulin.

What is the function of motor proteins?

They are responsible for muscle contraction and movement.

How do defensive proteins function in the body?

They provide protection against disease by destroying bacteria and viruses.

What is the role of transport proteins?

They transport substances, such as hemoglobin which carries oxygen in red blood cells.

What are receptor proteins responsible for?

They respond to chemical stimuli and help cells communicate.

What are structural proteins and give examples?

They provide support and structure; examples include keratin and collagen.

What is the basic building block of proteins?

Amino acids.

What type of bond forms between amino acids to create proteins?

Peptide bonds.

What is the significance of the R-group in amino acids?

The R-group (side chain) determines the characteristics and properties of each amino acid.

What are the two terminus ends of a polypeptide chain?

The N-terminus (amino end) and C-terminus (carboxyl end).
