Key Concepts

Fatty Acid

A fatty acid is a carboxylic acid that typically contains a long hydrocarbon chain, which can be either saturated or unsaturated. Fatty acids are key components of many biological lipids and are involved in energy storage, membrane structure, and signaling pathways.

Pentose

A pentose is a simple sugar with five carbon atoms. These carbohydrates form the building blocks for various biological molecules like nucleic acids, where they are critical components of the structure of RNA and DNA.

Dipeptide

A dipeptide is a molecule composed of two amino acids that are joined together by a peptide bond. This linkage results from a condensation reaction, releasing a molecule of water, and is an early step in protein synthesis and structure formation.

Diglyceride

A diglyceride is a type of lipid molecule formed when two fatty acid chains are esterified to a glycerol backbone. These molecules play important roles in cell membrane structure and metabolism, and serve as intermediates in the synthesis and breakdown of fats.
