Study Notes
Dehydration Reaction and Maltose Formation
- Glucose (C6H12O6) molecules combine via a dehydration reaction to create maltose (C12H22O11).
- The reaction is: C6H12O6 + C6H12O6 → C12H22O11.
Fat (Triglyceride) vs. Phospholipid Structure
- Triglycerides: Glycerol molecule with three fatty acids attached.
- Phospholipids: Glycerol molecule with two fatty acids and a phosphate group attached.
Polypeptide Structure and Bonds
- Secondary structure: Hydrogen bonds between atoms in the peptide chain.
- Tertiary structure: Interactions between amino acid side chains.
Greek Letters α and β in Structure
- α-glucose/β-glucose: Different arrangements of hydroxyl groups around the carbon atoms of glucose. Glycosidic bonds determine the specific arrangement.
- α-helix/β-pleated sheet: Common secondary structures in proteins, formed by hydrogen bonds within the polypeptide backbone. α-helices are coiled, β-pleated sheets are folded.
Amino Acid Groups in Polypeptides
- Polypeptides retain amino and carboxyl groups from the constituent amino acids from the ends.
- The carboxyl group of one amino acid bonds with the amino group of the next to create a peptide bond. This leaves an amino group at one end (NH2) and a carboxyl group at the other (COOH) of the polypeptide chain.
