Carbon starts out as a simple organic molecule, Carbon Dioxide. The leaf changes it into sugar, which is not a simple compound. It takes the sugar and changes that into a whole lot of different compounds.
DEfinitely ORGANIC , because it contains carbon atoms. It is a sugar molecule.
Sugar is an organic molecule because it contains carbon atoms. More rigorously, it contains carbon-hydrogen bonds.
carbohydrates
It is the formula for the simplest sugar molecule.
There are many examples of this, particularly in organic chemistry. Sucrose, for example, is a disaccharide commonly known as "table sugar." It is actually a glucose molecule and a fructose molecule, minus a water molecule, linked together.
The organic molecule that undergoes glycolysis is the sugar glucose which contains 6 atoms of carbon per molecule.
No, both are organic and should not have a polar bond.
The assumption is that life requires complex organic (i.e., carbon-based) molecules. Sugar, or other organic molecules, would be a first step. However, sugar is a fairly simple molecule; from sugar to life is still a huge step.
Fructose, or fruit sugar, is a simple monosaccharide found in many foods. The organic fructose molecule was first discovered in 1847 by Augustin-Pierre Dubrunfaut.
A simple fat molecule is composed of glycerol which is a simple sugar and 3 fatty acids, which are also chains of carbon and hydrogen with a carboxyl group at one end.
