Biological Molecules Flashcards
Where can you find DNA?
Nucleus
Four macromolecules
- Nucleic Acid (DNA/RNA)
- proteins
- lipids
- Carbohydrates
Another name for macromolecules
polymers
Monomers
The building blocks of polymers. Small molecules that join to form macromolecules
What makes lipids unique?
Polarity. They are generally non-polar, but some parts of some lipids can be polar
Pol
The monomer of lipids
None. It’s just one molecule
Monomer of carbohydrates
sugars
Monomer of Nucleic Acid (DNA/RNA)
nucleotides
Monomer of proteins
amino acids
Function of lipids
cell membrane and energy
Function of proteins
cell structure and support. Physical shape to things.
Function of nucleic acid (DNA/RNA)
carry genetic info
Function of carbs
energy
What differentiates amino acids from one another?
Their R group (also called side chain)
How do different types of carbohydrates form?
Bonding. The type of carb that forms depends on where the bonds between the sugars are formed.
Directionality
the order in which the monomers attach to one another to form a macromolecule
What is the importance of directionality?
The function and structure of the macromolecule depends on the directionality of its monomers
