DIPEPTIDASES Meaning and
Definition
-
Dipeptidases are a class of enzymes that play a crucial role in the digestion and breakdown of proteins in the human body. They are specifically responsible for the hydrolysis of dipeptides, which are molecules composed of two amino acids linked together by a peptide bond.
As proteins are essential macronutrients for various bodily functions, their digestion is a highly regulated process. Once ingested, proteins are initially broken down into smaller fragments called peptides, which are then further processed by dipeptidases into individual amino acids. This conversion is vital as it enables the absorption and utilization of amino acids for protein synthesis, energy production, and other metabolic processes.
Dipeptidases are primarily found in the brush border membrane of intestinal cells, specifically in the small intestine. They are commonly secreted by the enterocytes, specialized cells that make up the lining of the small intestine. These enzymes act on the terminal ends of dipeptides, catalyzing the cleavage of the peptide bond between the two amino acids. The resulting products are the free amino acids, which can be readily absorbed into the bloodstream through the intestinal wall.
The human body hosts several types of dipeptidases, each with specific substrate specificity for certain dipeptides. Examples include dipeptidase-1, also known as renal dipeptidase, and dipeptidyl peptidase IV (DPP-IV), which is involved in the regulation of blood glucose levels.
Overall, dipeptidases are essential enzymes that aid in the efficient digestion and assimilation of dietary proteins, promoting the overall health and well-being of an individual.

Etymology of DIPEPTIDASES
The word "dipeptidases" is derived from two main components: "di-" and "peptidases".
The prefix "di-" comes from the Greek word "dis", which means "two" or "twice". In this context, it refers to the fact that dipeptidases are enzymes that break down peptide bonds in peptides to release two amino acids.
The term "peptidase" is derived from the word "peptide", which originates from the Greek word "peptein", meaning "to digest". A peptidase is an enzyme that catalyzes the hydrolysis of peptide bonds in proteins or peptides, leading to their breakdown.
