Study Notes
Polymers
-
Polymer 2 (Phospholipid):
- Composed of a phosphate group and fatty acid tails.
- Forms a bilayer in cell membranes.
- Phosphate group is hydrophilic (attracts water).
- Fatty acid tails are hydrophobic (repel water).
-
Polymer 3 (Steroid):
- Cholesterol is a type of steroid.
- Important component of cell membranes.
- Makes the membrane sturdy and helps hold it together.
- Involved in hormone signaling
Proteins
-

- Made up of carbon, hydrogen, oxygen, and nitrogen (C, H, O, N).
-
Function:
- Crucial for structure and support.
- Act as enzymes, facilitating biochemical reactions.
-
Monomer:
- Amino acids.
-
Polymer:
- Polypeptide chain.
Nucleic Acids
-
Composition:
- Made up of carbon, hydrogen, oxygen, nitrogen, and phosphorus (C, H, O, N, P).
-
