Main forces between water molecules?
Water ability to disolve an ionic compound?
Water is a polar molecule with a negative end and a positive end. The hydrogen atoms have a partial positive end and the oxygen atom has a partial negative charge.
Add atomic weights
How many moles?
?/grams given = 1mole/grams molar mass
Storage form of carbohydrates in animals
Not digestable in humans
contains both a (1-4) and a (1-6) glycocidic bonds
Glycogen and amlyopectin
Contains only 1 (1-4) glycosidic bonds
Contains only b (1-4) glycosidic bonds
Contains both b(1-4) and a (1-6) glycosidic bonds
storage form of carbohydrates in plants
amylose and amylopectin
oh group down
oh group up
conpared to saturated fatty acids, fatty acids with a cis carbon-carbon double bonds
have lower melting points because cis carbon bonds don not allow for good packing
True or false? d glucose and l glucose are enantiomers
C=O with an H
Aldehyde = AL ending
= oic acid ending
N with h and side groups
- 2 H
Hydrolysis at physiological pH
+ H2O include charges
True or false? Water moves from a solution with lower osmolarity to one with a higher osmolarity.
