Definition

Carboxylic acids are organic compounds containing a carboxyl group (COOH). They play essential roles in the structure and function of proteins, particularly in amino acids.

5 Must Know Facts For Your Next Test

1. Carboxylic acids are characterized by the presence of a carboxyl group (-COOH).
2. Amino acids, the building blocks of proteins, often contain carboxyl groups.
3. The acidity of carboxylic acids is due to the resonance stabilization of their conjugate base.
4. Carboxylic acids participate in peptide bond formation during protein synthesis.
5. They can be involved in metabolic pathways such as the Krebs cycle.
