Introduction

Main Biomolecules

Proteins
Lipids
Carbohydrates
Nucleic Acids

Biochemistry

principally concerned with the chemistry and molecular interactions of biological molecules associated with living systems

Enzymes

Proteins
catalyze biochemical reactions
-composed of amino acids

Metabolism

Catabolism -yield energy, degrade
Anabolism -take energy, assemble

Electronegativity

ability to attract electrons
H, P < C, S < N < O
-bond strength

Biochemical transfromation

1. Group transfer, add or remove
2. Oxidation-Reduction
3. Rearrangement, function changes
4. Cleavage, break, add water
5. Condensation, form, remove water

Saturated hydrocarbons

C-H, C-C
non-polar
non-reactive
