Carbon BondingCarbon Bonding

Organic Compounds: made primarily of carbon atoms

Carbon is the molecule of life

Carbon Bonding (cont)Carbon Bonding (cont)

A carbon atoms has 4 e- in the outer most level So it can form four covalent bonds

with other atoms Carbon Video

Carbon Bonding (cont)Carbon Bonding (cont)

Carbon-based molecules have three general types of structures

a. Straight chain

b. Branched chain

c. Ring

Large Carbon Large Carbon MoleculesMolecules

Monomers: smaller, simpler molecules

Polymers: molecule made up of repeating monomers

Macromolecule: Large polymers 4 main ones found in living

organisms Draw and LABEL this image on the Left Column

1. NUCLEIC ACIDS1. NUCLEIC ACIDS

Function: Store and transfer genetic information.

Made up of C, H, O, P, N

Monomer = nucleotide

Nucleotides: 3 basic parts Phosphate group a sugar nitrogen containing base

There are four nucleotides A, C, G, T in DNA

1. NUCLEIC ACIDS1. NUCLEIC ACIDS

Examples: DNA and RNA

2. PROTEINS2. PROTEINS Monomer= Amino acids

Made from C, H, O, and N

Same basic structure but differ at functional (R) group

20 amino acids

2. PROTEINS2. PROTEINS Peptide bond: holds amino acids

together

Polypeptide: formed from long chains of amino acids

2. Proteins (cont)2. Proteins (cont)
