- The Starting Point of Food Chemistry
Molecules are chemical structures that are made up of even smaller building blocks: atoms. You could compare it with Legos: an atom is a single lego brick, whereas a molecule is the structure that is made from putting several bricks (at least two) together. Molecules can be small, made up of as little as two atoms. But food also contains plenty of ...
To start comparing different molecules in food, it is important to know what elements they are made of. This is where chemical formulas come into play. Each molecule can be expressed by such a formula* and it will tell you exactly which elements it is made of. A chemical formula is the ‘ingredient list’ of your molecule. To write up a chemical form...
Of course, chemical formulas are just the beginning! Just about every food is made up of a lot of different molecules, with each its own chemical formula. Up next is understanding how these molecules, interact and impact your food. All of that is exactly what food chemists do day in day out. Understanding and knowing chemical formulas is the starti...

Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, milk as examples.
The food we eat has three main types of macro-nutrients: carbohydrates (sugars), fats (lipids) and proteins (polymers of amino acids). In this section we will look at the structures and properties of each of these major classes of chemicals.
