BioChemistry Proteins (17%) Flashcards
The Essential AAs
PVT TIM HALL
Two semi-essential AA
Histidine
Arginine
AA that are aromatic
Phenylalanine
Trytophan
Tyrosine
Basic AA
HAL
Neutral AA
STAG
AA containing sulfur
Methioninie
Cysteine
AA that are not glucogenic
LL
Branch Chain AA
LIV
AA that are acidic
Glutamate
Aspartate
Digestion of Proteins occur in
Stomach and Small Intestine
Left over carbon skeletons from AA metabolism are either
Glucogenic (from Pyruvate or Oxaloacetate to make glucose)
Ketogenic (from Acetyl CoA to make ketones)
Which AA donate Nitrogen for purines and pyrimidines
Glutamine
Aspartate
Asparagine
The six AA muscles are able to oxidize
GAL VIA
What is the functon of the urea cycle
Rid the body of toxic Ammmonia
What is the enzyme used for urea cycle
Carbamoyl Phosphate Synthetase
Important Intermediates from the Urea Cycle
Fumarate Arginine Citrulline Ornithine Glutamate Aspartate (Fargo,GA)
During exercise muscles make
Ammonia
Lactate
Glucose-Alanine Cycle
- Ammonia and Lactate made during excerise
- Alanine is made up of Ammonia and Lactate
- Alanine travels to liver and converted back to Amm and Lac
- Ammonia becomes urea and Lactate becomes glucose
- Glucose returns to the muscle via blood
The bonds between AA is called
Peptide bonds
Alpha helix and Beta pleated sheet are this kind of strucutre
secondary
Tryptophan is a precurosor for
Serotonin
Glutamate is a precurosr for
GABA
Histidine is a precurosr for
Histamine
Glycine is a precurosr for
Creatine
Alanine can be converted to
Pyruvate
Glutamine can be converted to
Glutamate
Glutamate can be converted to
a Ketoglutarate
Asparagine can be converted to
Aspartate
