AMIDO ACID Meaning and
Definition
-
Amido acid is a term used in biochemistry and organic chemistry to describe a molecule that contains both an amino group (-NH2) and a carboxyl group (-COOH) attached to the same carbon atom, known as the α-carbon. These two functional groups are crucial components of amino acids, which are the building blocks of proteins.
Amino acids are organic compounds that are vital for various biological processes, including protein synthesis, enzyme production, and cell signaling. There are 20 standard amino acids that naturally occur in proteins, each with its own unique side chain. These side chains distinguish one amino acid from another, giving them specific properties and functions.
Amido acids are formed when the α-carboxyl group of one amino acid undergoes a condensation reaction with the α-amino group of another amino acid, resulting in the formation of a peptide bond. This reaction is a key step in the process of protein synthesis, as these peptide bonds connect individual amino acids in a specific sequence to form a polypeptide chain.
Amido acids play a fundamental role in determining the structure and function of proteins. The sequence of amido acids in a protein chain determines its three-dimensional shape, which ultimately determines its biological activity and function. Understanding the properties and interactions of amido acids is essential for comprehending the complex world of proteins and their importance in various biological processes.

Etymology of AMIDO ACID
The word "amido acid" is a typographical error or a misspelling of the term "amino acid".
The etymology of the correct term "amino acid" can be broken down as follows:
1. Amino: The term "amino" comes from the Latin word "ammonium", which refers to ammonia. It is derived from the Greek word "ammos", meaning "sand" because ammonia was originally obtained from camel dung, which resembled sand particles.
2. Acid: The term "acid" originates from the Latin word "acidus", which means "sour". It is derived from the Proto-Indo-European root "h₂eǵ-" meaning "to be sour".
