Chapter 7 Lesson 1 Flashcards
What are the four levels of protein structure?
- Primary
- Secondary
- Tertiary
- Quaternary
What is the primary structure of a protein?
A chain of unique amino acids
What is the secondary structure of a protein?
Groupings and foldings into Alpha Helices and Beta Plates Sheets
What is the tertiary structure of a protein?
3-dimensional shape of a single polypeptide
What is the quaternary structure of a protein?
More than one polypeptide chain bonded together
What is the function of an enzyme?
Cutting and joining the molecules of life
What is the function of a hormone?
Carry molecular messages throughout the body
What is the function of an antibody?
Constantly fight battles in the bloodstream
What is the function of an infrastructure?
Support and move cells
What is the function of pumps, channels, and receptors?
Getting back and forth throughout the body
How would a proteins structure change if a hydrophilic molecule was changed with a hydrophobic one?
The proteins shape would go inwards clumping the molecules together more in the middle
Epidermal growth factor is a protein message telling cells that they have permission to grow. It would be classified as which protein type?
Hormone
How can you tell which amino acid side chains are nonpolar?
If they have CH3 bonds
How can you tell which amino acids form covalent disulfide bridges?
If they contain a SH bond
