How Do You Spell EXOPEPTIDASES?

Pronunciation: [ɛɡzˈə͡ʊpptɪdˌe͡ɪsɪz] (IPA)

Exopeptidases are enzymes that catalyze the hydrolysis of peptide bonds from the ends of proteins and peptides. The pronunciation of this word is "ek-soh-pee-ti-deye-siz" (ɛksəʊˈpɛptɪdeɪsɛz), with the stress on the second syllable. The prefix "exo-" means external, and "peptidase" refers to enzymes that break down peptide bonds. The plural of exopeptidase is exopeptidases, indicated by the final "s". Being able to spell and pronounce technical terms like this is important in the field of biochemistry and molecular biology.

EXOPEPTIDASES Meaning and Definition

1. Exopeptidases are a type of enzymes that hydrolyze the peptide bonds at the terminal ends of proteins or peptides. These enzymes catalyze the cleavage of amino acid residues from either the N-terminus or C-terminus of the protein, resulting in the release of small peptide fragments or individual amino acids.

   The action of exopeptidases is crucial in the final stage of protein digestion, as they work to break down proteins into smaller, more manageable molecules that can be readily absorbed by the body. They play a significant role in the digestive system by aiding in the further breakdown of partially digested proteins, which were not fully hydrolyzed by endopeptidases.

   Exopeptidases are classified based on their specific cleavage site. Aminopeptidases, which are exopeptidases that cleave amino acids from the N-terminus, remove amino acids one by one starting from the protein's amino terminus. Carboxypeptidases, on the other hand, cleave amino acids from the C-terminus of the protein, releasing individual amino acids or dipeptides.

   These enzymes are found in various tissues and organs, including the pancreas, where they are secreted into the small intestine to aid in protein digestion. Exopeptidases are also present in the brush border membrane of intestinal cells, allowing for further processing of peptides before they are absorbed into the bloodstream.

   Overall, exopeptidases significantly contribute to the efficient breakdown and utilization of dietary proteins by catalyzing the cleavage of peptide bonds at the ends of proteins, releasing smaller peptide fragments or individual amino acids.

Etymology of EXOPEPTIDASES

The word "exopeptidases" is derived from the combination of two root words: "exo-" and "peptidase".

1. "Exo-": It is a prefix derived from the Greek word "exo", meaning "outside" or "external". In the context of exopeptidases, "exo-" refers to the fact that these enzymes act on the external or terminal ends of proteins or peptides.

2. "Peptidase": This word is derived from the combination of the roots "peptid-" and "-ase". The root "peptid-" is derived from the Greek word "peptos", meaning "digested" or "dissolved". The suffix "-ase" in biology denotes an enzyme. Therefore, "peptidase" refers to an enzyme that breaks down or degrades peptides or proteins.
