Organic Compounds
7.6D Organic Compounds
Term | Definition |
---|---|
Atom | The smallest particle of an element, made of electrons, protons, and neutrons; basic unit of matter. |
Element | A pure substance composed of the same type of atom throughout; cannot be broken down into simpler substances. |
Molecule | A particle made of two or more atoms bonded together; the simplest structural unit of an element or compound. |
Compound | A substance made of two or more different elements that are chemically combined in fixed amounts and joined by chemical bonds. |
Organic Compound | A compound that contains organic carbon and other atoms, usually oxygen, hydrogen, nitrogen, phosphorus, and/or sulfur. |
Inorganic Compound | Does not contain the carbon-hydrogen atom combination that characterizes organic molecules; not of biological compounds. |
Carbon | Naturally occurring element of Earth; essential building block of organic compounds; represented as "C" with atomic number of 6 on the Periodic Table of Elements. |
Hydrogen | Lightest of all gases, occurring mostly in combination with oxygen in water; 1st & simplest element on the periodic table; 1 of the most common elements in the galaxy; represented as "H" with atomic number of 1 on the Periodic Table of Elements. |
Oxygen | Colorless & odorless gas; life-supporting component of air; forms about 20% of Earth's atmosphere; most abundant element in Earth's crust; produced with glucose during photosynthesis; consumed with glucose during cellular respiration; represented as "O" with atomic number of 8 on the Periodic Table of Elements. |
Nitrogen | Most abundant gas (78%) in the atmosphere; key element in organisms; represented as "N" with atomic number of 7 on the Periodic Table of Elements. |
Phosphorus | Mineral substance found in bones in combination with calcium; represented as "P" with atomic number of 15 on the Periodic Table of Elements. |
Sulfur | Pale-yellow, brittle nonmetallic element that occurs widely in nature, especially in volcanic deposits, minerals, natural gas, & petroleum; represented as "S" with atomic number of 16 on the Periodic Table of Elements. |
Carbohydrates | Biomolecules made of oxygen, hydrogen, and carbon that organisms use for structural support and energy storage; can be broken down into simple sugars (glucose) to provide energy; includes starches, fibers and sugars. |
Proteins | Biomolecules made of amino acids that perform biological functions; build and repair tissues, and supply energy when needed; group of nutrients that provides energy and building blocks for growth and repair of body tissues. |
Amino Acids | Nitrogen-containing organic molecules that are the building blocks of proteins. |
Lipids (Fats) | One of the nutrient-providing components of food; used as an energy source in the body, and found in butter, oils, nuts, meat, fish, and some dairy products. |
