WVSOM Amino Acids

Discriptions

QuestionAnswer
Carboxylic acid side chains pka around 4 so they are unprotonated and negatively charged at physiologic pH Are hydrophilic and can form hydrogen and ionic bonds Aspartate (aspartic acid) and Glutamate (glutamic acid)
All polar but not charged so H-bonding N residues in proteins are often glycosylated Asparagine Glutamine Tryptophan
Side chain pKa's are 10-12 so they are positively charged at neutral pH Ionic and H bonding Significant hydrophobic portions in proteins the chains frequently are hiding in the interior with the positive ends sticking out at the surface Arginine Lysine
Have hyroxyl (OH) groups OH is a common site of postranslational modification (esp phosphorylation) Polar but not charged so H-bonds Serine Threonine Tyrosine
Side chain has pKa of 6 so unprotonated at physio pH it is predominantly positively charged Can participate in H and ionic bonding Because it's side chain pKa is 6 it is a good buffer Histidine
Side chain is easily oxidized and reduced, can form covalent bonds Disulfide bonds are very important for the structure of many proteins Cystine (two cysteins with a disulfide bridge) can form in blood- can form calculi Cystein
Except for M the side chains have only C and H atoms Side chains aren't ionizable or polar so they are hydrophobic Degree of hydrophobicity varies V, L, and I are the "branched chain" amino acids (remember this) Glycine Alanine Proline Valine Leucine Isoleucine Phenylalanine Methionine

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
