CC PROTEINS Flashcards
(85 cards)
proteins comes from greek word proteios, which means?
of first importance
these macromolecules are polymers of covalently linked amino acids through peptide bonds. these group of molecules are synthesized by hepatocytes
PROTEINS
only proteins not synthesized by the liver
immunoglobulins
VWF
factor III
only produced by the plasma cells (russell bodies)
immunoglobulins
which can be produced by endothelial cells (weilbel-palade bodies)
VWF
which are produced by tissue in general
factor III
regulate balance between anabolism and catabolism
nitrogen balance
simplest form of protein
primary structure
linear sequence of AA connected by peptide bonds.
-responsible for protein identity
-responsible for protein net electric charge
primary structure
bend form of proteins
secondary structure
3-dimensional conformation
- groups of AA binding in such a manner that alpha-helix and B-pleated sheets are formed through winding of polypeptide chains but not yet linked
secondary structure
folding patter of protein structure
tertiary structure
actual 3-D configuration
- responsible for protein FUNCTION physical and chemical properties
TERTIARY STRUCTURE
only protein with no quaternary structure
albumin
larger protein complex w/ precise 3D conformation
quaternary structure
unaffected by denaturation (regulated by strong covalent peptide bonds)
primary structure
affected by denaturation (no linage, only winding of alpha & beta units)
secondary structure
first to be affected by denaturation
tertiary structure
affected by denaturation (regulated by hydrogen, electrostatic interactions)
quaternary structure
forms of proteins are affected by the positioning of its epitopes and is easily changed by denaturation
conformational
proteins
are not affected by neither of the positioning of the epitopes nor denaturation.
non-conformational proteins
only contains AA linked by peptide chains and only yield AA acids upon hydrolysis acc to shape
simple proteins
elongated insoluble and less denatured
fibrous proteins
spherical, soluble, and more easily denatured
globular proteins
