The Science of Food
| Term | Definition |
|---|---|
| Adenosine Triphosphate (ATP) | The compound composed of adenosine and three phosphate groups that supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis. |
| Amino Acid | An organic monomer which serves as a building block of proteins |
| Calorie | The amount of heat energy required to raise the temperature of 1 gram of water by 1 degree Celcius. The Calorie (with a capital C), usually used to indicate the energy content of food, is a kilocalorie. |
| Carbohydrate | A sugar in the form of a monosaccharide, disaccharide, or polysaccharide. |
| Chemical Bond | An attractive force that holds together the atoms, ions, or groups of atoms in a molecule or compound. |
| Chemical Indicator | A substance (as a dye) used to show visually, usually by its capacity for color change, the condition of a solution with respect to the presence of free acid or alkali or some other substance. |
| Chemical Reaction | Chemical transformation or change; the interaction of chemical entities. |
| Compound | A substance consisting of two or more elements in a fixed ratio. |
| Covalent Bond | A type of strong chemical bond in which two atoms share one or more pairs of valence electrons. |
| Dehydration Synthesis | A chemical reaction in which two molecules are bonded together with the removal of a water molecule. |
| Disaccharide | A double sugar molecule made of two monosaccharides bonded together through dehydration synthesis. |
| Element | The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms. |
| Glucose | A monomer of carbohydrate, simple sugar. |
| Homeostasis | The maintenance of relatively stable internal physiological conditions (as body temperature or the pH of blood) in higher animals under fluctuating environmental conditions. |
| Hydrolysis | A chemical process that splits a molecule by adding water. |
| Ionic Bond | A chemical bond resulting from the attraction between oppositely charged ions. |
| Lipid | One of a family of compounds including fats, phospholipids, and steroids that is insoluble in water. |
| Macromolecule | A type of giant molecule formed by joining smaller molecules which includes proteins, polysaccharides, lipids, and nucleic acids. |
| Molecule | Two or more atoms held together by covalent bonds. |
| Monomer | The subunit that serves as the building block of a polymer. |
| Monosaccharide | A single sugar molecule such as glucose or fructose, the simplest type of sugar. |
| Nutrient | A substance that is needed by the body to maintain life and health. |
| Polymer | A large molecule consisting of many repeating chemical units or molecules linked together. |
| Polysaccharide | A polymer of thousands of simple sugars formed by dehydration synthesis. |
| Protein | A three dimensional polymer made of amino acids. |
