Macromolecule Molecular Structure
Carbohydrates - simple and complex sugars
Assemble and draw the following macromolecules found in the boxes.
Simple Sugar - monosaccharide
example: glucose and fructose
Fructose can be straight or in a ring make the ring structure
Glucose can be straight or in a ring make the ring structure

“The structure of glycogen is essentially as shown in the following
drawing, except that in the complete glycogen molecule there are 12 layers
whereas for simplicity only 5 are shown in the drawing:
The essential features of this general structure are that each B-chain has
two branch points, and all chains have the same length, as the experiments
showed that the material is distributed at 50% between A- and B-chains.
In addition it is worth noting the molecule of glycogenin, a protein that acts
as a primer, at the centre of the structure.”

Proteins - made of amino acids are large globular molecules
Assemble the building blocks of amino acids.
In order to make an amino acid, assemble an amino functional group NH2 and a carboxyl functional group COOH.

Once you have assembled these two groups take a carbon atom this will be the hub of your amino acid.
On the left hand side attach the amino group, and on the right hand side attach the carboxyl group.
On the bottom of your carbon hub to the back place a hydrogen atom.
This is the basic structure of all amino acids.
Different amino acids have different (R) Groups attached to the last bond site of the carbon hub

Enzymes - are specialized proteins that act as biological catalysts to speed up the rate of reactions
Enzymes bond to substrates with specificity often referred to as lock and key or hand
and glove.
