Proteins Flashcards
What are monomers of proteins?
Amino acids
What type of bonds connect amino acids?
Peptide bonds
Name the four levels of protein structure
Primary
Secondary
Tertiary
Quaternary
What happens when a protein is denatured?
It loses its shape and function
What are the monomers of proteins?
Amino acids.
What is a polypeptide?
A long chain of amino acids linked by peptide bonds.
What bond forms between amino acids?
Peptide bond (via condensation reaction).
What are the four levels of protein structure?
Primary: Sequence of amino acids.
• Secondary: Alpha helices & beta sheets.local folding
• Tertiary: 3D folding due to side chain interactions.
• Quaternary: Multiple polypeptides combined.
What happens when a protein is denatured?
It loses its shape and function due to heat, pH, or chemicals.
What are the main components of an amino acid?
Central carbon, amino group, carboxyl group, and R-group.
What determines the shape of a protein?
The sequence and properties of amino acids.
How many different amino acids exist?
20; their combinations create protein diversity.
What factors cause protein denaturation?
Temperature, pH, and chemical exposure
