Biochem terms I don't know Flashcards
Triacyglycerols
the most abundant lipid category. They are the main components of animal (including human) fat, most of which is concentrated in adipose tissue; they are also the main components of vegetable oils. Because of this abundance, they constitute 90% to 95% of dietary fat
valine
essential, non-polar
amino acid synthesized in plants. It is noteworthy in hemoglobin, for when it replaces
glutamic acid at position number six, it
causes hemoglobin to aggregate abnormally
under low oxygen
conditions, resulting
in sickle cell disease.
Asparagine (Asn/N
is a non-essential
amino acid coded by AAU and AAC. Its carboxyamide in the R-group gives it polarity.
Leucine (Leu/L)
Leucine (Leu/L) is a branched-chain amino
acid that is hydrophobic and essential.
Leucine is the only dietary amino acid reported to directly stimulate protein synthesis in muscle,
hypotonic
concentration of solutes is greater inside the cell than outside water will tend to move into the cell causing the cell to swell
hypertonic
if the solute concentration is greater outside the cell than inside of it
then water will exit the cell and the cell will shrink
isotonic
concentrations of solutes inside and outside of the cell is equal
symports
proteins that move two molecules in the same direction across a membrane
antiport
two molecules are moved in opposite directions across the bilayer
isonophores
proteins involved in moving ions
electrogenic transport
movements that result in change of charge
if simple diffusion is the driving force the process is called _____ and if the process requires other energy input, the process is _____
facilitated diffusion , active transport
ligand gated ion channels
transmembrane proteins which open to selectively allow ions such as Na+, K+, Ca++ or Cl- to pass through the membrane in response to the binding of a ligand messenger
voltage gates channels are essential for ____
transmission of nerve signals
___ selectively allow ions to pass based on size and energy of dehydration/hydration
ion channels
