Proteins in General
Proteins are made from 20 different
amino acids
sequence of amino acids
primary structure
sickle cell occurs in this structure of the protein
primary structure
T/F proteins have four main structures
true
T/F proteins are made of amino acids
true
Proteins account for more than this much mass of cells
50%
What determines the primary structure of a protein
DNA sequence in the nucleus
genetic disorder where red blood cells are shaped like crescents rather than saucers
sickle- cell anemia
Proteins are composed of which molecules? a. amino acids b. fatty acids c. monosaccharides d. nucleic acids
a. amino acids
Which of the following foods do not belong to the protein group a. meat b. fish c. nuts d. pasta
d. pasta
The sequence of amino acids determines this
the shape of the protein
folding or coiling of a protein chain
secondary structure
the main symptom of sickle cell is
a person is very tired
hemoglobin is made from this number of polypeptides
four
complete proteins are
The shape of the protein is the biggest factor that determines its
function
Two types of secondary structure
helix and folded pleated sheet
T/F sickle cell will affect all four protein structure
true it begins in the primary and will affect secondary, tertiary and quaternary
Form between atoms of sulfur within the protein
disulfide bond
results when two or more smaller polypeptides with different shapes join together.
quaternary structure
List the five functions of proteins
structural support
storage and transport
cellular communications
movement
defense against foreign substances
3D shape of the protein
tertiary structure
This terms means a protein is misshapen and is biologically inactive
denatured
What determines tertiary structure
hydrogen bonds, ionic bonds, Van der Waals interactions
What two effects do disulfide bonds have on hair
curly hair and the burnt hair smell so bad
