L3 - The Dawn of proteins Flashcards
Why are amino acids with aliphatic/aromatic R groups always hydrophobic and non-polar?
X
Amino acids with aliphatic/aromatic R groups are …
hydrophobic and non-polar
What are the hydrophobic and non polar amino acids?
aliphatic: Alanine, valine, leucine, isoleucine, methionine
aromatic: phenylalanine, tyrosine, tryptophane
Which amino acids are charged?
acidic (negative charge): aspartate, glutamate
basic (positive charge): Lysine, arginine, histidine
Which amino acids have polar side chains?
Cysteine, serine, threonine, asparagine, glutamine
Which amino acids have non polar side chains?
alanine, valine, leucine, isoleucine, methionine
phenylanaline, tyrosine, tryptophane
small amino acids
glycine and proline
which amino acids are aromatic?
phenylalanine, tyrosine, tryptophane
which amino acids are aliphatic? XXXXX
Alanine, isoleucine, leucine, proline, and valine (internet)
alanine, valine, leucine, isoleucine, methionine (lecture)
Which amino acids are prebiotic?
glycine, alanine, valine, leucine, isoleucine, proline, serine, threonine, aspartate, glutamate
Which amino acids are basic?
Lysine, arginine, histidine
Which amino acids are acidic?
aspartate, glutamate
What makes an amino acid non polar?
when their side chains are comprised of mainly hydrocarbons
Whya re non polar amino acids hydrophobic?
water is polar, like things interact with like things, non polar moelcules cannot form H bonds with water
polar uncharged AAs
cysteine, glutamine, asparagine, threonine, serine
