2. Carbohydrates A carbohydrates is a is an organic compound with general formula Cm(H2O)n, that is, consisting only of carbon, hydrogen and oxygen, A Carbohydrate is an organic compound with general formula Monosaccharide's are the simplest carbohydrates in that they cannot be hydrolyzed to smaller carbohydrates The term is most commonly used in biochemistry, where it is essentially a synonym of saccharine Carbohydrates can be viewed as hydrates of carbon, hence their name. The term is most commonly used in biochemistry, where it is essentially a synonym of saccharine

3. Fat Fats consist of a wide group of compounds that are generally soluble in organic solvents and largely insoluble in water fats are generally trimesters of glycerol and fatty acids. Fats may be either solid or liquid at normal room temperature, depending on their structure and composition. Although the words "oils", "fats", Fats form a category of lipid, distinguished from other lipids by their chemical structure and physical properties

4. Protein Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues.

5. minerals A mineral is a naturally occurring solid formed through geological processes that has a characteristic chemical composition, a highly ordered atomic structure, and specific physical properties. rock, by comparison, is an aggregate of minerals and/or mineralogist, and need not have a specific chemical composition.

6. water Water is a ubiquitous chemical substance that is composed of hydrogen and oxygen and is essential for all known forms of life In typical usage, water refers only to its liquid form or state, but the substance also has a solid state, ice, and a gaseous state, water vapours or steam.

7. vitamins A vitamin is an organic compound required as a nutrient in tiny amounts by an organism The term 'vitamin' first became popular in the early 1800's as a contraction of the words 'vital' and 'mineral'
