Do I know the 4 Biomolecules?
--Carbohydrates, Lipids, Proteins, and Nuclei Acids (Carlos like pounding nails)
--Do I know the monomer and polymer for each?
Monomers
C-monosaccharide
L-triglyceride (1 glycerol and 3 fatty acids) P-amino acid N-nucleotide
Polymers
C-polysaccharide, L-none, P-polypeptide chains that make proteins, N-DNA and RNA
Would you recognize the molecules of each??
How to tell what the Molecule is:
CHO-Carbohydrates –only have these three elements –you will see carbon rings that are not fused together but look like they
are holding hands---NO NITROGEN NO PHOSPHATE VISIBLE
CHO-Lipids-only have these three elements how to tell the difference because Carbs and lipids only have CHO is that there are
no rings and they should…should….have a glycerol and three fatty acid tails or two tails, or 1 tail unless it is a phosphorlipid
there should be no Phosphate present in the picture , definitely no Nitrogen
CHON—Proteins…Look for nitrogen and phosphate if there is no phosphate but there is Nitrogen it has to be a protein or
amino acid. How to tell look for a backbone or repeating N-C-C-N-C-C-N
Look for a central Carbon and an R-group it will either be a ring or literally say R and then you will see a Nitrogen
CHONP- if you see a Phosphate and Nitrogen then it’s a nucleotide or a chain of DNA or RNA and is Nucleic Acid
What kind of foods contain each?—look in your notes
If it was ever alive or came from a living organism it has DNA so—nucleic acids
Meats have carbs, lipids, proteins, and nucleic acids
Veggies—carbs, lipids, nucleic acids
Fruit—carbs, lipids, nucleic acids
Beans-proteins and carbs and nucleic acids
Oil--lipids
What are the functions of each?—look in your notes
Transmit information/genetic/make proteins---NUCLEIC ACID
ENERGY—Carbs, Lipids
Cell reaction, growth, repair, movement, -----Proteins
Lipids-cell membrane, chemical messenger, not soluble in water, insulation
Carbs—cell walls, photosynthesis
WHAT ABOUT ENZYMES??
What are the parts involved—substrate,enzyme, active site, enzyme-substrate complex, products, inhibitor
Can you recognize them???? They don’t always look like pac man
Do I know what INDUCED FIT IS and can recognize this happening but the shape of the active site changing to fit the substrate
at the bonding?
Do I know the difference between COMPETITIVE and NONCOMPETIVE INHIBITORS? (which one enters the active site and
which one binds to a different spot but changes the active site so the substrate can no longer bind to enzyme?)
What does the Enzyme do?
Where do we have them?
How many does a cell have?
ENZYMES are Proteins don’t forget that!!
