Living things
are made up of
organic molecules
which contain
nucleic acids
,
proteins
,
carbohydrates
, and
lipids.
Triglycerides
are formed by a
reaction
among
three fatty acid molecules
and
one glycerol.
Lipids
are
insoluble
molecules made of
C
,
H
, and
O.
Phospholipids
have
hydrophobic tails
and
hydrophilic heads.
Enzymes are a type of
protein
, which function to
speed up chemical reactions.
Carbohydrates
include
glycogen
and
cellulose.
Lipids
store
long-term energy
,
protect vital organs
,
form
cell membranes
, and are
subdivided
into
triglycerides
,
phospholipids
, and
steroids.
Polysaccharides
are many
monosaccharides
joined together,
store energy
or
provide
structure
, for example,
starch.
Polymers
are
long chains
made of
repeating units
called
monomers
, symbolized as
'poly'
and
'mono'.
The
four levels
of
protein structure
are:
primary
,
secondary
,
tertiary
, and
quaternary.
The
four
basic classes of
organic molecules
are:
Carbohydrates
,
Lipids
,
Proteins
, and
Nucleic Acids.
Enzymes
are
proteins
that have a
general function
and are responsible for catalyzing
chemical
reactions.
Carbohydrates
supply
energy
to
cells
, are made up of
C
,
H
, and
O
, and their smallest unit is
monosaccharides
, for example,
glucose.
Biological macromolecules
are the
giant molecules
of
life.
Disaccharides
are
two monosaccharides covalently bound
to
each other
, for example,
sucrose.
Properties of water are
cohesive
,
high melting point
,
high boiling point
, and
high heat
of
vaporization
Water cohesive
means water molecules
stick
together ( called
stickiness
)
Lipids
do
not
have
monomers
Saturated
fats are
solid
at room temperature and contain
one
bond
Unsaturated
fats are
liquid
at room temperature and contain
one
or
more double
bonds between the
carbon
atoms.
The
functions
of proteins are
structural
,
transport
,
movement
and
chemical
reactions
