• Via 🌊 condensation reactions, think of it as LEGO bricks coming together!
• Each time a fatty acid and glycerol combine, a water molecule pops out. It's like squeezing a sponge! Do it thrice, and you get three water molecules.
• The special link between fatty acid and glycerol is called the ester bond (imagine it as the superglue holding our LEGO bricks together).
  • Fun Fact: Ester bonds are like a handshake 🤝 between the acid part of the fatty acid (carboxyl –COOH group) and the alcohol part of the glycerol (hydroxyl –OH group).
• Since we use up the only friendly, water-loving (hydrophilic) parts in this bonding, triglycerides turn into complete water-haters (hydrophobic).

• Depends on the type of fatty acids in the mix! Think of it like choosing ingredients for a smoothie; different ingredients = different taste & texture.

Structure Peep: They're like the cousin of triglycerides! But with a twist.

• They have two fatty acids and one glycerol.

• BUT, instead of the third fatty acid, they sport a cool phosphate group.

Water Love-Hate Relationship

• The phosphate head is like you at a pool party - loves to jump in (hydrophilic)!

• But the fatty acid tails? They're the shy ones, avoiding the water (hydrophobic).
