How Do You Spell THIOLASE?

Pronunciation: [θˌa͡ɪə͡ʊlˈe͡ɪs] (IPA)

Thiolase (/θaɪəˈleɪz/) is a word used in biochemistry that refers to an enzyme which removes an acetyl group from a molecule. The spelling of the word can be attributed to its etymology, which comes from the Greek word "thio," meaning sulfur, and the ending "-lase" which denotes an enzyme. The phonetic transcription of the word shows that the "th" sound is pronounced as a dental fricative and the "o" sound is a diphthong, consisting of two vowel sounds.

THIOLASE Meaning and Definition

1. Thiolase is an enzyme that plays a crucial role in the breakdown and metabolism of fatty acids. Specifically, it is involved in a process called beta-oxidation, which occurs primarily in the mitochondria of cells.

   The thiolase enzyme catalyzes the fourth step in the beta-oxidation pathway, which involves the cleavage of a two-carbon unit from a fatty acyl-CoA molecule. This process releases acetyl-CoA, which can be further metabolized to produce energy or used for various other cellular processes.

   Thiolase achieves this reaction by utilizing a unique coenzyme called coenzyme A (CoA), which is attached to the fatty acyl group. The enzyme forms a thioester intermediate between the acyl group and CoA, which is subsequently cleaved to release acetyl-CoA. The liberated acetyl-CoA can enter the citric acid cycle to generate ATP, a crucial energy source for cellular functions.

   Thiolase is an essential enzyme in organisms that rely on the metabolism of fatty acids for energy, such as mammals, insects, and certain microorganisms. It plays a vital role in maintaining energy balance, particularly during prolonged fasting or periods of intense physical activity. Additionally, thiolase also contributes to the synthesis of ketone bodies, molecules that serve as alternative energy sources when glucose availability is limited, such as during starvation or certain metabolic disorders.

   Understanding the function of thiolase is relevant not only for elucidating metabolic processes and energy balance but also for developing targeted therapies for metabolic diseases related to fatty acid metabolism dysfunction.

Etymology of THIOLASE

The word "thiolase" has its etymology rooted in the Greek language. It is derived from two Greek words: "thio" meaning "sulfur" and "lase" meaning "to break". The suffix "-ase" in biology commonly refers to enzymes. Therefore, the term "thiolase" specifically refers to an enzyme that breaks down or forms chemical compounds involving sulfur atoms.
