Element | A substance that cannot be decomposed into simpler substances by chemical means, and is made up of atoms all with identical number of protons. |
Compound | A material made up of two or more parts or elements |
Organic compounds | An organic compound always contains carbon. |
Inorganic compounds | Inorganic compounds can be defined as any compound that is not organic compound. Some simple compounds that contain carbon are often considered inorganic. |
Carbohydrates | are molecular compounds made from just three elements: carbon, hydrogen and oxygen. |
Lipids | A lipid is an organic molecule of biological origin that is insoluble in water and soluble in non-polar solvents. |
Proteins | A molecule composed of polymers of amino acids joined together by peptide bonds. |
Enzymes | Catalysts which speed up chemical reactions, but remain unchanged themselves. Substrate. the substance which an enzyme works on. |
Nucleic acids | consist of either one or two long chains of repeating units called nucleotide, which consist of a nitrogen base (a purine or pyrimidine) attached to a sugar phosphate. |
Hydrolysis | A chemical reaction in which water is used to break down a compound. |
Synthesis | The production of an organic compound in a living thing, especially as aided by enzymes. |
pH | pH is a measure of the hydrogen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH. |
