The function of a protein is its amino acid sequence
determined by its
three-dimensional
conformation. Therefore, the
function
of a protein is ultimately due to
what
characteristic of the protein?
, Covalent Bond -sharing of electrons
-can be polar or non-polar
-ex. CO2
Hydrogen Bond -weak attraction between a hydrogen atom
and
another atom
-negative region of a molecule attracted to
positive region of a molecule
Ionic Bond -between cation and anion
-gain/loss of electron(s)
-disassociation occurs in water
-ex. NaCl
Glucose and glycogen are carbohydrates
examples
of what group of organic
compounds?
Which class(es) of organic -proteins
compound can provide a source of -carbohydrates
energy for cells? -lipids
Decomposition Reaction a reaction in which a single compound
breaks
down to form two or more simpler
substances
-ex. HCl → H+ + Cl-
