Plants
Frucotse
Function
Disaccharides
madeup two monosaccharides
formed by a
Covalent bond
with a
Glycosidic Linkage
Examples
for
Animals
Lactose
Breaks
into
Gluose + Galactose
by the lactase enzyme
has a alpha (1-4) linkage
Maltose
Breaks
into
Glucose + Glucose
by the lactase maltase
has a beta ( 1-4) linkage
Plants
Sucrose
Breaks
into
Glucose + Galactose
by the lactase sucrase
has an alpha(1-4) linakge
Polysaccharides
made up of many monosaccharides formed by a
Covalent bond
with a
Glycosidic linkage
Function
used for
Storage
the poly involves is
Starch
used in plants
provides a structural unit for plants
the poly involved is
Cellulose
used in plants
provides sugar for
Energy
is stored in
Glycogen
used in animals
used for short term
BY: LUL ZERGABER
Lipids
Function
provides
Long term energy
Storage molecules in the body
In charge of
Digestion
Insulation
Fat soluble vitamins
Food Storage
Chemical Signalling
Structural Function
Consist of
Carbon
and hydrogen =
Bonds
results in being
Insoluble in H20
which means its
Hydrophobic
Hydrogen
Oxygen
Storage
in
Plants
are
Oils
Animals
are
Fats
Forms
Trigylceride
Most common form of lipids
Composed of a Glycerol + 3
Fatty Acids
Saturated
Can result in situated health problems
are bonded by a
Ester Bond
so it will have a straight chain
are solids at room temperature
Unsaturated
are bonded by a
Double Bond
so it will have kinks
are liquids at room temperature
forms fats in
Adipose cells
form together through an
Esterficaton Reaction
the bond formed is an
Ester Linkage
is the monomer of lipids
Waxes
Contain
long -chain fatty acids that are linked to alchols or carbon rings
form molecules
Cutin
that
helps pants conserve water and resist dsease
forms a water resistant coating on
leaves
fruits
stems
Steriods
contain
Cholestral
maintains fluidity in lipid bilayer
are incorperated into vitamins and bile
are part of sex hormones
have harmful
Effects
Acne
Bad breath
Kidney Disease
Phosphalipids
composed of a
Glycerol molecule
and is attached to
2 non polar fatty acids (tail)
highly polar phophate group (head)
in H20 they two possible arrangments
Phospahlipid bilayer
Ring
Hydrogented fats
Do not exist in nature
processed naturally from fats and oils by convertingcis to trans form
Is done by bubbling hydrogen gas into oil at a high temperture
Trans Fats
Are creted through hydrogenation. This process helps the shelf life and taste of the product
After hydrogenation,, they are now partially hydrogenated
Proteins
Monomer
is
Amino Acids
Joined by
Dehydration Synthesis
Removes the H20
a covalent bond
100-200 make
Protein Polymer Chains
change in
Sequence
causes blood clots
change in shape
possible sickle cell anemia
response to physical and chemical
Conditions
alter in PH levels
Temperature
Denaturing
meaning breaking down
Salt concentration
there are 20 different amino acids
Structure
Depicts its
Function
which is
Transport Molecules
they facilitate diffusion
Storage
for energy
Enzymes
accelerate chemical reactions
Defense against foreign substances
immunoglobins
Movement
cells traveelling through the flagells or cillia
Hormones
some carry chemical signalling
Structural support
give it shape
Contains
A Hydrogen and R group
Amino Group
Carbxylic Acid
Central Carbon
Levels
Primary
are joined by a peptide bond
Secondary
polypeptide forms pleated sheet and are held by hydrgoen bonds
Tertiary
side chains form to make it 3D so ti determines a variety of R groups
Quatnary
take on a rounded shape and not all proteins have this structure
Nucleic Acids
Monomer
Nucleotide
consists of
A Phosphate group
Sugar w/ 5 carbons
Nitrogen containing bade
Types
Pyrimidines
have single six-membered ring
Cytosine, Thymine and Uracil
Purines
have a six-membered ring jpined to a five membered ring
Adenine and Guanine
vs.
Nucleotideds
generally lack phosphate group
one or more phosphate groups covantly bonded to creates a
one of the 4 DNA bases covalently attached to a sugar
Types
DNA
functions to
provide direction for own replication
Directs RNA synthesis (through RNA)
Has a role of protein expression, Inhertance, and Evolutions
Pairings
3 H bonds for between Guanine and Cytosine
they are complementary strands
2 H bonds form between Adenine and Thymine
H bonds not covalent bonds because they need to be able to replicate itslef
