Triglycerides and Phospholipids

Flashcards covering key concepts related to triglycerides and phospholipids, their formation through condensation reactions, and the components involved.

Triglycerides

Lipids composed of one glycerol molecule and three fatty acid molecules.

Phospholipids

Molecules formed when one inorganic phosphate group replaces one of the three fatty acids in triglycerides.

Glycerol

A three-carbon molecule that links to fatty acids to form triglycerides and phospholipids.

Condensation Reaction

A chemical process in which two molecules combine with the release of water.

Fatty Acids

Carboxylic acids with long hydrocarbon chains that are key components of triglycerides and phospholipids.

Carboxyl Group

Functional group (-COOH) present at the end of fatty acids involved in condensation reactions.

Covalent Bond

A chemical bond formed by the sharing of electrons between atoms, such as between glycerol and fatty acids.

Hydroxyl Group

A functional group (-OH) that is present in glycerol and involved in forming covalent bonds.

Inorganic Phosphate

A phosphate group that replaces one fatty acid in the formation of phospholipids.

Macromolecules

Large complex molecules made up of smaller subunits, such as lipids, proteins, and carbohydrates.
