Questions And Answers Real Set
Molecules of life ANS carbohydrates, lipids, proteins, nucleic acids
Macromolecules ANS A very large organic molecule composed of many smaller molecules
Polymer ANS A long molecule consisting of many similar or identical monomers linked together by
covalent bonds.
Monomer ANS Small molecules that serve as the building blocks of polymers.
monomer of carbohydrates ANS monosaccharides
monomer of proteins ANS amino acids
monomer of DNA ANS nucleotide
dehydration synthesis ANS A chemical reaction in which two molecules covalently bond to each other
with the removal of a H2O molecule.
Hydrolysis ANS A chemical process that splits a polymer by adding a H2O molecule.
covalent bond ANS A chemical bond that involves sharing a pair of electrons between atoms in a molecule
Carbohydrates ANS Primary source of energy (ATP). Made of 3 elements: C, H, O.
Isomers ANS Two different molecules that have the same chemical formula, but different chemical
structure.
Disaccharide ANS A double sugar, consisting of two monosaccharides joined by dehydration synthesis.
, Polysaccharides ANS Carbohydrates that are made up of more than two monosaccharides
glycosidic linkage ANS A covalent bond formed between two monosaccharides by a dehydration reaction.
Lipids ANS Fats, oils, waxes, steroids. Second source of energy (ATP). Made of triglycerides.
Triglycerides ANS a compound made up of a single molecule of glycerol and three molecules of fatty acid.
ester bond ANS bond that connects the glycerol and fatty acid in fat molecules
saturated fats ANS fats that are solid at room temperature. Have hydrogen atoms.
unsaturated fats ANS fats that remain liquid at room temperature. Missing hydrogen double bond.
Monounsaturated ANS one double bond
polyunsaturated ANS more than one double bond
Phospholipids ANS a lipid consisting of a glycerol bound to two fatty acids and a phosphate group.
Phosphate group is hydrophilic. Lipid tail is hydrophobic.
phosphate group ANS A functional group consisting of a phosphorus atom covalently bonded to four
oxygen atoms
Hydrophilic ANS Attracted to water
Hydrophobic ANS Water fearing
phospholipid bilayer ANS Plasma membrane layers composed of phospholipid molecules arranged with
polar heads facing the outside and nonpolar tails facing the inside.
