You Must Know • How the sequence and subcomponents of proteins determine their properties. • The cellular functions of proteins. (Brief – we will come back to this in other chapters.) • The four structural levels of proteins and how changes at any level can affect the activity of the protein. • How proteins reach their final shape (conformation), the denaturing impact that heat and pH can have on protein structure, and how these may affect the organism. • The directionality of proteins (the amino and carboxyl ends).

You Must Know• How the sequence and subcomponents of proteins
determine their properties.• The cellular functions of proteins. (Brief – we will come
back to this in other chapters.)• The four structural levels of proteins and how changes
at any level can affect the activity of the protein.• How proteins reach their final shape (conformation),
the denaturing impact that heat and pH can have on protein structure, and how these may affect the organism.
• The directionality of proteins (the amino and carboxyl ends).
Concept 3.5: Proteins include a diversity of structures, resulting in a wide range of functions
• Proteins account for more than 50% of the dry mass of most cells.
• Protein functions include defense, storage, transport, cellular communication, movement, and structural support.
