14946408810polymerA large molecule composed of repeating structural units or monomers.0
14946408811carbohydrateCompound containing carbon, hydrogen, and oxygen in the approximate ratio of C:2H:O (e.g., sugars, starches, and cellulose)1
14946408812proteinClass of nutrients made up of amino acids, and the chief building block of life. They are needed to build and repair body structures, and to regulate processes in the body2
14946408813lipidOrganic molecules made of carbon, hydrogen, and oxygen and store food energy until needed (fats). Triglycerides store 2x as much energy as carbs, and steroids play an important role in growth and development.3
14946408814amino acidBuilding blocks of protein4
14946408815monosaccharideA single sugar. This simple sugar is the basic subunit of a carbohydrate5
14946408816fatty acidBuilding blocks of lipids6
14946408817macromoleculeA very large molecule (as of a protein, nucleic acid, or carbohydrate) built up from smaller chemical structures7
14946408818enzymeA protein that makes a reaction happen QUICKER; helps break down food.8
14946408819polysaccharidea carbohydrate that is composed of many monosaccharide units joined together9
14946408820glucoseA simple sugar that is an important source of energy. AKA "blood sugar".10
14946408821disaccharideA molecule composed of two monosaccharides. Common disaccharides include maltose, sucrose, and lactose.11
14946408822polysaccharideA polymer of thousands of simple sugars. A carbohydrate that is composed of many monosaccharide units joined together12
14946408823monosaccharideA simple sugar that is the basic subunit of a carbohydrate13
14946408824protein functionsStructural, protection, regulatory, contractile/motile, chemical reactions, transport. (Know an example of each...)14
14946408825CarbonThe element that is the foundation of molecular structure for all living things. It is the only element that has the ability to bon with such a variety of other elements which allows for the structure of everything from simple sugars, to complex compounds like proteins , DNA, and diamonds.15
14946408826Elements in the body96% is made up of carbon, hydrogen, nitrogen, and oxygen. Trace elements include: calcium, phosphorus, potassium, sulfur, sodium, chlorine, magnesium, and others.16
14946408829Lactosea disaccharide milk sugar made up of glucose and galactose17
14946408834StarchA storage polysaccharide in plants consisting entirely of glucose. Starches are a complex carbohydrate because the body first has to break down long chains into simple sugars before it can burn them.18
14946408835CelluloseA substance (made of sugars) that is common in the cell walls of many organisms. This becomes dietary fiber for humans and is not digestible. Fiber is important for moving bulk through the digestive tract, it slows absorption of sugar, etc.19
14946408836Triglyceridesan energy-rich compound made up of a single molecule of glycerol and three molecules of fatty acid.20
