1
Q

Organic Compound

A

Any compound containing Carbon and any functional group

2
Q

Why carbon?

A
  1. Common
  2. 4 Valence electrons
  3. Binds to other carbons, forms complex backbones
  4. Forms variety of covalent bonds
  5. Versatile (can bond to many other atoms)
3
Q

Functional Group

A

Small cluster of atoms that determines properties of organic compounds

4
Q

Examples of Functional Groups

A
Hydroxyl
Methyl
Carboxyl
Amino
Phosphate
5
Q

Monomer

A

Single building block of a larger molecule, can exist independently

6
Q

Dimer

A

Two monomers bound together

7
Q

Oligomers

A

Small group of bound monomers (<10)

8
Q

Polymers

A

Long chain of monomers (>10)

9
Q

Dehydration Synthesis

A

Reaction that forms polymers by chemically combining monomer units

10
Q

What is released during Dehydration Synthesis

A

Water

11
Q

Process of Dehydration Synthesis

A

2 OH groups react, H2O is released, remaining O binds monomers

12
Q

Hydrolysis

A

Large reactant is broken down to form smaller products through addition of water.

13
Q

A

Chains of arbon atoms with a carboxyl on one end, and a methyl on the other end

25
Q

Main function of fatty acids

A

Energy storage

26
Q

What do fatty acids form

A

Triglycerides

27
Q

Triglyceride

A

3 fatty acids + glycerol

28
Q

How are triglycerides formed

A

Dehydration synthesis between three OH of glycerol and 3 OH of fatty acids

29

A

Multiple double bonds

34
Q
