How Do You Spell XANTHINE DEHYDROGENASE?

Pronunciation: [zˈanθa͡ɪn dˌiːha͡ɪdɹˈə͡ʊd͡ʒne͡ɪs] (IPA)

The word "Xanthine Dehydrogenase" is spelled as /zanθin diːhaɪˈdrɒdʒɪneɪz/ in IPA phonetic transcription. The first syllable "xan" is pronounced as /zan/ with a voiced alveolar nasal consonant followed by the vowel sound /æ/. The second part "thine" is pronounced as /θin/ with the voiceless dental fricative /θ/ and the vowel sound /ɪ/. The last part "dehydrogenase" is pronounced as /diːhaɪˈdrɒdʒɪneɪz/ with stress on the second syllable and a blend of sounds including the voiced dental fricative /ð/, the aspirated stop consonant /h/, and the voiced palato-alveolar affricate /dʒ/.

XANTHINE DEHYDROGENASE Meaning and Definition

1. Xanthine dehydrogenase is a key enzyme that plays a crucial role in purine metabolism, specifically in the breakdown of purines into uric acid. It is an oxidoreductase enzyme that catalyzes the interconversion of xanthine and uric acid, an important step in the metabolism of nitrogenous bases.

   Xanthine dehydrogenase belongs to the family of molybdenum-containing enzymes and requires molybdenum cofactor (MoCo) as an essential component for its enzymatic activity. This enzyme is widely present in different organisms, including animals, plants, and microorganisms. In humans, it is mainly expressed in the liver and small intestine.

   The enzyme possesses both dehydrogenase and oxidase activities, depending on the availability of molecular oxygen. Under normal physiological conditions, xanthine dehydrogenase predominantly functions as a dehydrogenase, using NAD+ or NADP+ as an electron acceptor. However, when oxygen levels decrease, it can be converted to xanthine oxidase, which generates reactive oxygen species (ROS) as a byproduct.

   Xanthine dehydrogenase deficiency has been associated with a rare genetic disorder called xanthinuria. This condition is characterized by the accumulation of xanthine and hypoxanthine in the urine, leading to the formation of xanthine stones and other related complications.

   Overall, xanthine dehydrogenase is a vital enzyme involved in purine metabolism, contributing to the appropriate regulation of uric acid levels and the overall maintenance of cellular homeostasis.

Etymology of XANTHINE DEHYDROGENASE

The word "Xanthine Dehydrogenase" is derived from two main sources: the term "xanthine" and the term "dehydrogenase".

1. Xanthine: The term "xanthine" originated from the Greek word "xanthos", meaning "yellow". Xanthine is a naturally occurring compound that is a yellowish-white powder. It was first isolated from yellow urine stones, thus the name. The suffix "-ine" suggests that it is a nitrogenous compound.

2. Dehydrogenase: The term "dehydrogenase" is derived from two parts: "dehydro" and "genase".

- "Dehydro" comes from the word "dehydrated", which means to remove water. In chemistry, removing water from a compound is often associated with removing hydrogen atoms.
