van der Waals correct answer: -weakest (short lives) but lots could strengthen the bond 
-furthest distance 
-form as a result of hydrophobic interactions 
-strength depends on the size of the atoms and the distance between them 
-cannot be closer than the Van der Waals contact distance or else positively charged nuclei will repel each other (energy= 0) 
 
Proteins correct answer: main action molecule of the cell (Most chemical processes of the body are carried out by proteins) 
-classified in...

- modulate cell-cell recognition (glycoproteins & glycolipids) 
 
What's responsible for membrane formation correct answer: decrease in ionic interactions w/ h2o (HYDROPHOBIC EFFECT) 
-h20X tails aggregate to hide from h2o (lots of n-c interactions)

sucrose correct answer: glucose + fructose with a glycosidic bond 
 
simple monosaccharide correct answer: formula: (CH2O)n 
-simplest carbohydrates 
-have an aldehyde or ketone group 
sugars with a aldehyde have a prefix aldo- 
sugars with a ketone group have a prefix keto- 
-if a ketose, the ketone group is always at carbon 2- this decreases the amount of isomers that could form 
-made up of chiral carbons- allowing the sugars to form different isomers, leading to structural diversity (aldos...
