|
Explain the role of hydrogen bonding in the formation of all of the the biological macromolecules |
Important in protein secondary structure ( beta pleated sheets & alpha helix) |
|
|
Be able to sketch generic dehydration synthesis and hydrolysis reactions |
Sketch it & check notes |
|
|
Be able to sketch a generic amino acid, identify the amino and carboxyl groups, and sketch how they are involved in peptide bond formation |
Sketch & check notes |
|
|
Be able to place a given amino acid structure and one of the groups, and know why it matters which group a particular amino acid belongs to |
L or D. Important because d amino acid is not in humans, only bacteria |
|
|
How do you recognize when a molecule has stereoisomers |
4 diff substituents |
|
|
What is meant by protein primary secondary and tertiary structure |
Primary - peptide bonds Secondary - H bonds between NH and C double bond O Tertiary - interactions between R groups of amino acids |
|
|
What types of interactions are involved in protein tertiary structure formation |
Hydrogen bonding, ionic bonding, Vanderwall‘s interaction, disulfide bonds |
|
|
What is the difference between an alpha helix and the beta pleated sheet |
Alpha helix is coiled while beta pleated sheet swoops in and out of rows |
|
|
How does a proteins structure determine its function |
Particular arrangement of helicis, turns, etc. to allow ligand binding and protein movement |
|
|
What is the difference between alpha and beta glycocitic bonds, and why is this important |
Alpha - dipped down between sugar Beta- straight in between Important bc enzyme can get to alpha easier, so easier to digest. Humans don’t digest beta
|
|
|
Draw structures of ribose, phosphate, and nucleotides to form a nucleoside triphosphate |
Sketch & check |
|
|
What is the difference between the five prime and the three prime end of a nucleic acid polymer |
Five prime and has a phosphate attached to the number 5 of carbon on sugar. Three prime end has an a OH attached to the number three carbon of the sugar |
|
|
A simple structures of glycerol, fatty acid’s, and phosphate to form a phospholipid |
Sketch & check |
|
|
What are saturated cis unsaturated and trans unsaturated fatty acid’s |
Saturated - straight, packs tightly, solid, animals and bacteria Cis unsaturated - very bent, packs loosely, liquid, plants and bacteria Trans unsaturated - slightly bent, packs tightly, solid, bacteria |
|
|
How do phospholipids and proteins assemble into a biological membrane |
Phospholipids are amphipathic, therefore they form membranes |
|
|
Know how to draw glycine, proline, and cysteine |
Sketch |
