1.Organic compound | Chemical compounds that contain both carbon and hydrogen. |
2.Inorganic compound | Chemical compounds that contain either carbon or hydrogen. |
3.Carbohydrate(s) | Any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. |
4. Protein(s) | Any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms. |
5.Lipid(s) | Any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. |
6. Enzyme(s) | A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. |
7. Amino acid(s) | A simple organic compound containing both a carboxyl (—COOH) and an amino (—NH2) group. |
8. Simple sugars | Sweet in taste and are broken down quickly in the body to release energy. |
9. Disaccharide | The sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage. |
10. Ribonucleic acid | A nucleic acid that is generally single-stranded , and composed of repeating nucleotide units of ribose sugar, phosphate group, and nitrogenous base. |
11. Deoxyribonucleic acid | A double-stranded nucleic acid that contains the genetic information for cell growth, division, and function. |
12. Polysaccharide | A polymer made of many saccharide units linked by glycosidic bonds. |
13. Glycogen | A branched polymer of glucose that is mainly produced in liver and muscle cells, and functions as secondary long-term energy storage in animal cells. |
14. Peptide | A short chain of amino acids. |
15. Catalyst | A substance capable of initiating or speeding up a chemical reaction. |
16. Denature | Process modifying the molecular structure of a protein. |
17. Hydrolysis | A chemical reaction in which water is used to break down a compound |
18. Dehydration synthesis | The process of joining two molecules, or compounds, together following the removal of water. |
19. Substrate(s) | A molecule acted upon by an enzyme. |
20. Nucleotide(s) | One of the structural components, or building blocks, of DNA and RNA |
21. Fatty acids and glycerol | The building blocks for lipids |
22. Dipeptide | A compound consisting of two amino acid units joined at the amino (–NH 2) end of one and the carboxyl (–COOH) end of the other. |
23. Coenzyme | Nonprotein molecules although some are vitamins, particularly those that are phosphorylated derivaties of water-soluble vitamins. |
24. Macromolecules | A very large molecule, such as protein, commonly created by the polymerization of smaller subunits (monomers). |
