Hydocarbon, condensation reactions, and hydrolysis reactions Flashcards
By the end you must be able to explain the concept of electronegativity, and how it influences biological molecules
1
Q
What is carbon
A
- all life on earth is carbon-based
- can form 4 covalent bonds
- can result in a wide variety of molecular shapes (straight chain, branched chain, ringed, and diamond)
2
Q
What are biologically important macro molecules
A
Carbs
fats
protein
nucleic acids
3
Q
What does hydrocarbon contain
A
carbon and hydrogen
4
Q
Is hydrocarbon polar or non polar
A
Non polar (En is .35)
5
Q
What are hydrocarbon chains the backbone of
A
CHO, FA, pr-, and NA
6
Q
How are all four macromolecules formed
A
a condensation reaction (or an anabolic reaction)
7
Q
what are condensation reactions also called
A
dehydration reactions
8
Q
What are the two functional groups in condensation reactions
A
- one loses a hydrogen atom
- one loses a hydrogen atom and a oxygen atom
9
Q
What is hydrolysis reaction
A
all four biological macromolecules are broken down (catabolic state)
10
Q
What is waters involvement in a hydrolysis reaction
A
water is used to break down the covalent bond between functional groups
11
Q
What are the two functional groups in hydrolysis reaction
A
- one group that takes a hydrogen
- the other takes a hydrogen and an oxygen
