Bonds
a chemical bond that involves the sharing of electrons to form electron pairs between atoms.
What is a covalent bond?
Water molecules attracted to one another through hydrogen bonding (Hint- reason for high surface tension)
What is cohesion?
The building blocks of life
Bonds between monosaccharides
What are glycosidic bonds?
An attraction between two atoms that already participate in other chemical bonds
What is a hydrogen bond?
What is adhesion?
pH above 7
What is a basic pH?
Large molecules made up of many similar moleculecular building blocks
What is a polymer?
Carbohydrate monomers
A type of chemical bond that generates two oppositely charged ions.
What is an Ionic bond?
Takes more energy to raise water temp
What is high specific heat?
pH of 7
Joining two monomers together into a polymer, removing a water molecule in the process.
What is dehydration synthesis?
Triglycerides
What are three fatty acids+ glycerol?
A pair of electrons shared unequally by two atoms

What is 6 and 8?
What is a hydrolysis reaction?
Non polar regions that are often hydrophobic
What are fatty acids?
Pair of electrons shared equally by two atoms
What is a nonpolar covalent bond?
Highest energy molecules evaporate first, cooling the surface of the remaining liquid
What is evaporative cooling?
Substances produced in cells that prevent harsh dramatic changes in pH
Derived from petroleum oil and developed by scientists and engineers
