Definition of Biochemistry
Biochemistry is a set of tools, or technical skills, that lend themselves to many diverse scientific
fields, most of which are related to the study of biomedical research: i.e. diseases, biomarkers,
biotechnology, etc.
1.5 Primordial Universe
Predominated by He and H
Today dominated by C, H, N, O, P & S
1.6 Human Body Elements
Main element of body - hydrogen followed by oxygen and carbon.
Main element of Earth Crust’s – Silicon, Aluminum
1.8 Periodic Table: From a Biochemists Perspective
An element is a basic substance that cannot be broken down into anything more basic
1.10 Carbon-based Biological Macromolecules
To survive, we need our body to make our building blocks – called macromolecules, which are
made up of other smaller subunits of simple organic molecules.
Chains are made when combinations of subunits undergo a linkage step called a condensation
reaction, which involves the removal of a water molecule.
3 essential macromolecules – Nucleic Acid, Proteins and Carbohydrates
1.11 Nucleic Acids
DNA and RNA
Basic structure - A ribose sugar, phosphate at 5’ carbon and 1’ carbon has ¼ nitrogenous
bases
Difference – At the 2’ location - DNA has a hydrogen and RNA a -OH group attached. Also, for
the bases, RNA does not use Thymine, but instead uses Uracil
1.13 Proteins
Made up of amino acids (20 different kinds)
Backbone of each amino acid is an amino group and a carboxyl group. The R group denotes
