What are the different types of proteins?
|
DMCSST
Defense - antibodies Movement - motor and contractive proteins. Catalysis - enzymes (speed up chemical reactions) Signaling - peptide hormones that bind to receptor proteins Stucture - fingernails/ hair. Transport proteins. |
|
|
monosaccharides
|
simple sugars
(mono = one) |
|
|
polysaccharides
|
polymers that form when monosaccarides are linked together.
POLY = more than one ** used to store energy (starch and glycogen) |
|
|
What is the difference between covalent and ionic bonding?
|
covalent bond = the partners SHARE a pair of electrons. (co = two)
Ionic = ONE partner captures the electron from the other. |
|
|
hydrolysis
|
seperates polymers by adding water.
- lowers the potential energy of the electrons involved. |
|
|
glycogen
|
used as storage in animals
[similar to starch/storage in plants] |
|
|
membrane transport
|
combo of size and charge (-/+) that affects the need of transport proteins. {permeability}
|
|
|
RNA
|
double stranded - secondary structure similar to protein.
|
|
|
cellulose
|
part of the cell wall.
|
|
|
lipids
|
fats (ex. oils)
|
|
|
nucleotide
|
a phosphate group linked covalently (shared electrons) to a five carbon sugar ring.
|
|
|
phospholipid
|
a 3 carbon molecule (glycerol) that is linked to a phosphate group that gives polarity with a negative charge.
|
|
|
amino acids
|
acidic due to highly electronegative oxygens.
- makes it easy to loose protons (polor/hydrophilic) |
|
|
fatty acid
|
hydro carbon chain bonded to a water loving [hydrophilic] head.
|
|
|
membrane proteins
|
allows cell-cell interactions
-senses environment. |
|
|
peptide bond
|
c-n bond between amino acids because of the condensation reactions. (stabes electrons because they're partially shared).
