|
What are the building blocks of proteins called? |
Amino acids |
|
|
|
How many protein building blocks are there? |
20 biologically important amino acids |
|
|
|
When a solution of amino acids is placed in a plane polarized light, what happens? |
Rotate the light to the left -called L amino acids -Leuorotatory |
|
|
|
Name the aliphatic amino acids |
Glycine (Gly) Alanine (Ala) Isoleucine Leucine (Leu) Valine |
5 of them - GAIL V |
|
|
What does R- mean? |
Any organic side chain |
|
|
|
Name the amino acids where R = hydroxyl group |
Serine Threonine Tyrosine |
3 of them - #rd letter = r |
|
|
What is the organic structure of a hydroxyl group? |
-OH (polar since O is so electronegative) |
|
|
|
Name the amino acids where R contains S |
Cysteine (Cys) Methionine (Met) |
|
|
|
What is the food source of amino acids that contain S? |
-Cruciferous veggies + asparagus -onions and garlic -animal products (Sulfur = antioxidant) |
|
|
|
Draw the concept map of anti-oxidation using R-SH |
2R - SH +H2O2 —> R - S - S - S (add H2O) = S - S disulfide bond/bridge created 2 cysteine = cystine |
|
|
|
What “amino acid” contains a disulfide bond or bridge? |
Cystine = 2 cysteine are joined by a disulfide bond |
|
|
|
Name the acidic amino acids |
Aspartic acid Glutamic acid (has one more C than aspartic) |
2 of them |
|
|
Name the salts of the acidic amino acids |
Aspartate Glutamate (Food example containing salt: MSG = monosodium glutamate) |
2 of them |
|
|
What is the charge of the salts of the acidic amino acids? |
Negative |
|
|
|
Name the amides of the acidic amino acids |
Asparagine Glutamine |
2 of them |
|
|
Name the basic amino acids |
(They have an extra amine group that gets charged.) Histidine (His) Arginine (Arg) Lysine (Lys) |
3 of them |
|
|
What is the charge of the basic amino acids? |
Positive |
|
|
|
Name the aromatic amino acids |
Phenylalanine Tyrosine Tryptophan (Phenylalanine can easily be made into tyrosine so tyrosine is non essential; tryptophan is essential) |
3 of them |
|
|
Name the imino acid |
Proline (pro) (Important in collagen) |
|
|
|
List the essential amino acids |
Phenylalanine (Phe) Valine Tryptophan (Try) Threonine (Thr) Isoleucine Methionine Histidine Arginine (Arg) Lysine Leucine |
10 of them - PVT TIM HALL |
