Amino acids Flashcards
proteins are chains of
amino acids
changing polar to nonpolar amino acid can cause
sickle cell anemia (from glutamic acid to valine)
building block of protein
amino acid
how many naturally occurring amino acids do we have
20
proteins are macromolecules that have amino acid polymers joint together by______ bonds
covalent
amino acids make linear molecule a polymer that can fold into
three dimensional structure
if a normal protein is heated, had a pH change, salt or has been shaken mechanically, it will
loose its function and become denatured protein
basic components of an amino acid
Carbon in the middle amine group carboxyl group (acid group) hydrogen side chain
how do we differentiate amino acids types?
by the side chain
what can a side chain contain in an amino acid?
alkyl group aromatic compounds amino groups carboxyl groups hydroxyl groups sulfur-containing groups
how many amino acids that are hydrophobic
9
how many amino acids that are hydrophilic
11
how to determine hydrophobic proteins
tend to cluster on the inside of the molecule
amino acids are classified as hydrophobic when the side chains are
alkyl groups
hydrogen
aromatic
hydrophobic (non polar) R groups:
Glycine Alanine Valine Leucine Isoleucine Methionine Phenylalanine Tryptophan Proline
