The function of carbohydrates?
main source of energy
Monomer and polymer of carbohydrates
monomer- monosaccharide
polymer- polysaccharide
Two types of carbohydrates?
Aldose and Keytose
Aldose is where?
End
Keytose is where?
mid
Disaccharides are what type of reaction?
dehydration reaction
What are disaccharides formed by?
Two monosaccharides (carbs)
What linkages are disaccharides?
Ether linkages (dehydration reactions)
Disaccharides are what type of reations?
dehydration reaction
maltose is made out of ^ ^
glucose + Glucose +H2O
Lactose is made out of ^ \/
glucose + glactose +H2O
Sucrose is made out of ^ /_\
glucose + fructose
Polysaccharides are what type of linkages
many ether linkages by many monosaccharides
Polysaccharides are starch, cellulose, glycogen T or F
T
starches are many alphas put together?
T
Cellulose is many betas put together?
T
Glycogen is many alpha put to gether that build off each other
T

1,4
Lactose is what type of # bonding
1,4
Sucrose is what # of bonding
1,2
Starch is used for what?
plant food storage molecule
Cellulose is used for what?
structural components in cell walls
Glycogen is used for what?
- animal food storage molecules
- similar to starch but with more braces.
Proteins control the rate of chemical reactions through enzymes T or F
T
Proteins transport in and out of the cell T or F
T
Monomer of protien
amino acid
polymer of protien
polypeptide
proteins have what type of weird group?
Radical group fro amino acid
protein structure - primary
little beads
amino acids linked together and form peptide bonds
Protein structure - secondary
two single wavey coil
-amino acids linked together by hydrogen bonds
-ex hydrogen bonds, disulphide bridges, ionic bonds and hydrophobic interactions
protein structure - Tertiary
waved and coiled togter
-attractions are present between pleased shapes
-decided to coil up due to hydrogen bonds
protein structure- Quanatary
scribbled together
-some proteins are a combination of 2 or more polypeptide chains
-proteins may have inorganic compounds
- each combination of poly peptide chains produces a different protien
Lipids function
store energy and makeup biological membranes
no polymers of lipids because…
because its not composed of repeating units of the same molecules or atoms
what is glycerol
a lipid
properties what is a hydrocarbon
-non polar
-low boiling points
-hot water soluble
-combustible
why is benzene a special hydrocarbon?
alternate single double bonds between the carbons
bonds move around
resignates between 2 forms
t or F energy is required to break down bonds
T
t or f energy is released when new bonds are formed
T
endergonic means
require energy
exergonic means
gives off energy
how do chemical reactions speed up
catalsits
