question
Polymer
answer
Large compound formed from combinations of many monomers
question

question
Monosaccharide
answer
Single sugar molecule; monomers of disaccharides and polysaccharides.
question
Monosaccharide
answer
Large molecule formed from monosaccharides
question
Polysaccharide
answer
Macromolecule made mostly from carbon and hydrogen atoms; used to store energy, part of biological membranes, and waterproof coverings
question
Disaccharide
answer
Two single sugar monomers bonded together. Examples are sucrose and lactose and maltose.
question
Disaccharide
answer
Fatty Acid with all single C-C bonds. No double bonds. Found primarily in animal products. Solid at room temp.
question
Saturated Fat
answer
Fatty Acid with at least one double C=C bond. Has a kink in the structure. Found in Plant products. Liquid at room temp.
question
Unsaturated Fat
answer
Polysaccharide that plants use to store food (sugar). Animals can easily digest.
question
Glycogen
answer
Polysaccharide that animals use to store food (sugar). Usually in liver and muscles.
question
Cellulose
answer
Polysaccharide that plants build themselves out of; most common organic molecule on earth.
question
Triglyceride
answer
Fat used by most animals. Three fatty acids bound to a glycerol molecule.
question
Triglyceride
answer
A phosphate containing, hydrophilic head with two hydrophobic fatty acid tails.
question
Phospholipid
answer
Molecule that loves water; attracts to water
question
Hydrophobic
answer
Molecule that fears water
question
Dehydration synthesis Reactions
answer
Only chemical reaction used by living things to build polymers. Creates water as a by-product. Also called Condensation Rxns.
question
Dehydration synthesis Reactions
answer
Chemical Reaction used by living things to digest or break down polymers into monomers by splitting water apart.
