amino acids Flashcards
glycine
non polar hydrophobic
alanine
non polar hydrophobic
valine
non polar hydrophobic
leucine
non polar hydrophobic
isoleucine
non polar hydrophobic
proline
non polar hydrophobic
non chiral and simplest amino acid
glycine
alanine has a ___ group instead of a hydrogen
methyl
only ring structure , not aromatic
proline
three rules of aromaticity
rings
planar, unhybridized p orbitals overlapping to form a continuous ring of planar orbitals
must follow huckels rule
having 4n+2 electrons in its system of conjugated p orbital c louds where n is an integer
aromatic compounds
phenylalanine
tyrosine
tryptophan
basic amino acids
histidine lysine and arginine
sulfur containing amino acids
methionine and cysteine
acid amino acids
aspartate and glutamate
make post synaptic neurons more likely to fire
aspartate and glutamate
amide amino acids
asparagine
glutamine
in which amino acids are the hydrophobic side chains
glycine (Gly), alanine (Ala), valine (Val), leucine (Leu), isoleucine (Ile), proline (Pro), phenylalanine (Phe), methionine (Met), and tryptophan (Trp).
six amino acids have side chains that are polar but not charged. These are
serine (Ser), threonine (Thr), cysteine (Cys), asparagine (Asn), glutamine (Gln), and tyrosine (Tyr). These amino acids are usually found at the surface of proteins
