Match the type of carbohydrate with its description:
Monosaccharides = Simplest carbs (simple sugars) Polysaccharides = Long chain carbohydrates, used for food storage Disaccharides = Carbohydrates formed due to glycosidic bonds Micromolecule = Another term for monosaccharides
Match the carbohydrate role with its function:
As the body's main source of energy = Glucose As food storage compounds = Polysaccharides Form structural components in plant cells = Long chain carbohydrates Excess consumption results into stored fat = Long chain carbohydrates
Match the carbohydrate type with its characteristics:
Monosaccharides = Highly soluble in water, can pass through cell membranes Polysaccharides = Includes sugar, starch, and fibers Disaccharides = Formed due to combining two monosaccharide molecules Micromolecule = Simplest form of carbohydrates
Match the carbohydrate with its alternate name:
Glucose = Dextrose Carbohydrates = Hydrate de carbone (French) / saccharide (sakcharon, Greek) Monosaccharides = Simple sugar Polysaccharides = Long chain carbohydrates
Match the carbohydrate type with its composition:
Monosaccharides = (CnH2nOn) Polysaccharides = (C6H10O5)n Disaccharides = (C12H22O11) Micromolecule = (CH2O)n
Match the carbohydrate with its abundance in nature:
Glucose = Most abundant monosaccharide in nature Fructose = Found in the bloodstream and provides immediate source of energy Sucrose = Commonly found disaccharide in nature Starch = Widely present polysaccharide in plants
Match the carbohydrate with its description:
Maltose = Formed from glucose with a glycosidic bond and the release of one molecule of water Fructose = The sweetest among all sugars, found in flowers, molasses, and honey Galactose = Found as a component of lactose in milk, produced in the body through digestion of lactose Sucrose = The most abundant disaccharide, composed of one molecule of each two monosaccharides
Match the carbohydrate with its source:
Lactose = Milk sugar Maltose = Found in germinating grains and used to make beer Sucrose = A.K.A. table sugar Polysaccharides = Stored carb in plants
Match the lipid term with its function:
Saturated fats = Fatty acid chain is straight, solid at room temperature, mostly found in animals Cholesterol = Contributes to the structure of cell membranes and production of hormones Triglycerides = Consists of one glycerol molecule bonded with three fatty acid molecules Lipids = Play an important role in cell membrane, absorption of vitamins, and insulation of the body
