What are the 5 Polar Charged Hydrophobic Amino Acids?
Group C
Why are amino acids called Amino acids?
They have an amine group and a carboxyl group
What is the significance of the alpha carbon atom?
It is between the carboxyl and amino group
In which isoform (L/D) are most natural amino acids?
L-form
What’s so special about glycine?
No asymmetric carbons due to Hydrogen as the R-group
What’s so special about Methionine?
It contains Sulfur
What’s so special about proline?
It forms a kink in a protein due to a ring structure
What is so special about serine, threonine, and tyrosine?
They have a hydroxyl group that easily soaks up H20
What’s so special about aspartate and glutamate?
negative charged
Whats so special about Lysine, Arginine, and Histidine?
They are positively charged
What’s so special about cysteine?
It can form a disulfide bond with another cysteine.
