-
Where are all AA derived from?
Intermediates in glycolysis, TCA cycle or pentose phosphate pathway
-
How does nitrogen enter Glycolysis, TCA, and Pentose shunt?
Via glutamine and glutamate
-
How many AA can Bacteria/Plants/Animals synthesize
- Plants/bacteria: All 20
- Animals: Can only synthesize 10 simple AA, need to eat the rest (the ones eaten are the essential aa)
-
Overview of AA Biosynthesis
-
General Transamination Reaction
- Carried out by aminotransferase
- Switches O and NH3 f carboxylic acid and amine
-
Role of alpha-keto glutarate
-
Non-essential AA pathways
-
3-Phosphoglycerate Family (Ser, Gly, Cys)
-
Arginine Synthesis
- Comes from alpha-ketoglutarate
- Via Urea cycle
- Children need it, adults make enough
-
Synthesis of Tyr, Phe, Trp
-
All amino acids derived from what intermediates:
Glucose, 3-Phosphoglyceric Acid, Phosphoenolpyruvic acid, Pyruvate, alpha-KG, OAA
-
Essential Human Amino Acids
- Val, Met, His, Leu, Phe, Lys, Ile, Thr, Trp, Arg
- Very Many Hairy Little Pigs Live In The Torrid Argentina
-
-
Porphyrin Biosynthesis
- Glycine is basic part
- Aminolevulinate is used in repetitive condensation reactions to make porphyrin
-
Heme B and Chlorophyll
- Porphyrins:
- Heme b has cofactor Iron, Chlorophyll has cofactor Mg
- Chlorophyll also has fatty acid chain to help anchor it
