Amino acids Flashcards
Phenylalanine metabolism: Enzyme targeted in Parkinson’s
dopa decarboxylase
inhibiting dopa decarcobylase results in inhibiting dopa conversion to dopamine
Enzyme catalyzing conversion of dopa to melanin
tyrosinase
Cofactor needed for phenylalanine–>tyrosine
BH4
Cofactor needed for tyrosine–> dopa
BH4
Cofactor needed for dopamine–>NE
vit C
Cofactor needed for dopa–>dopamine
vit B6
Cofactor needed for NE–>Epi
SAM
Enzyme catalyzing dopa to dopamine
dopa decarboxylase
Hormone that facilitates converting NE to epi
cortisol
Amino acid required in heme synthesis
glycine
PVT TIM HaLL?
Phenylalanine Valine Threonine Tryptophan Isolecuine Methionine Histidine Leucine Lysine
Basic AA’s
Lysine (extra ammonia group)
Arginine (extra ammonia group)
Histidine
Chirality of amino acids found in proteins
L-
Acidic AA’s
Aspartic acid
Glutamic acid
Amino acids important during periods of growth
arginine
histidine
(BASE your build with BASIC amino acids…excluding lysine)
AA’s negatively charged at body pH
aspartate
glutamate
AA’s positively charged at body pH
arginine
lysine
Basic amino acid with NO charge
histidine
*the exception
other basic AA’s have positive charge at body pH
Amino acids important for nuclear localization signals
arginine and lysine
Amino acids heavily found in histones
arginine
lysine
responsible for POSITIVE charge –> allows easy association with NEGATIVELY charged DNA
Arginine required for
Creatine
Nitric oxide
Urea
AA precursor for Niacin
Tryptophan
Amino acids requiring B6 in production of their derivatives:
tryptophan
histidine
glycine
glutamate
AA precursor of porphyrin
glycine
heme synthesis
