Honors Biomedical Sciences Test 2: Day 1

Examples of ways carbon can be found

-single bond
-double bond
-triple bond
-carbon ring
-hydrocarbon chain

Carbon is very versatile

What type of bond is water?

polar covalent bond

6 functions of water

1. creates surface tension
-insects walking on water
-skipping rocks

2. can be in 3 states
-solid
-liquid
-gas

3. high heat capacity
-takes long to heat up, long to cool down

4. universal solvent
-dissolves many substances
- dissolved=solute
-not dissolved=solvent

5. adhesion
-water is attracted to other molecules

6. cohesion
- water is attracted to itself

solvent vs solute

dissolved=solute

not dissolved=solvent

salt=solute
water=solvent

little solute=dilute
little solvent=saturated
equal amount=concentrated

functional groups

1. hydroxyl group
-OH

2. carboxyl group
carbon double bonded to O, single bonded to OH

3. amine group
a nitrogen w/ two hydrogens (2 single bonds)
