Proteins Flashcards
Secondary structure of protein
Folded structure of a protein
Types of 2d fold structures
Alpha-helix or beta-pleated
Folded structure of a protein
Secondary structure of protein
Heteromultimeric
Different subunits in quaternary structure
Polypeptides
Long chains of amino acids
Polar
Hydrophilic
How many amino acids are there
20
What part of an amino acid is different for each one
Side chain
Long chains of amino acids
Polypeptides
Homomultimeric
Same subunits in quaternary structure
Peptide bonds
hold amino acids together
What are formed when amino acids bind
Peptides
How many essential amino acids are there
9
What protein structure of multiple polypeptide chains
Quaternary structure
What structure do side chains influence
Tertiary
What are the structures of protein from from lowest to highest
Primary, secondary, tertiary, quaternary
Hydrophilic
Polar
What forces contribute to folding
Van der waals forces, hydrogen bonds, electrostatic interactions
Largest protein
Titin
What do hydrogen bonds do that affects protein structure
Affect the secondary structure shapes
What protein structure is the sequence of amino acids
Primary protein structure
Chaperonins
Barrel shaped proteins that help fold proteins, proteins go into them and fold inside of them
Different subunits in quaternary structure
Heteromultimeric
What bonds cause the shapes
Hydrogen bonds
What bonds hold amino acids together
Peptide bonds
Hydrophobic
Non polar
What is the tertiary structure influenced by
Side chains (R groups)
Same subunits in quaternary structure
Homomultimeric
Hydrophobic
Barrel shaped proteins that help fold proteins, proteins go into them and fold inside of them
Chaperonins
Tertiary structure
3d folding of proteins
Peptides
formed when amino acids bind
