How Do You Spell AVIDIN?

Pronunciation: [ˈavɪdˌɪn] (IPA)

Avidin is a protein found in egg whites that binds biotin, preventing its absorption in the body. Its spelling contains three syllables: /ˈæv.ɪ.dɪn/. The first syllable begins with the short a vowel sound, as in "apple" or "cat." The second syllable has the short i vowel sound, as in "tip" or "sit." The third syllable also has the short i vowel sound, followed by the d consonant sound and then the short i vowel sound again. Overall, the pronunciation of avidin is straightforward with no unusual or silent letter pronunciation.

AVIDIN Meaning and Definition

1. Avidin is a protein that is found in raw egg whites, particularly in the white of chicken eggs. It is known for its strong binding capability with biotin, also referred to as vitamin B7 or vitamin H. Avidin is a tetrameric glycoprotein, meaning it consists of four identical subunits that are connected together. These subunits bind with high affinity to biotin, forming an avidin-biotin complex.

   Avidin is highly resistant to heat and digestion, making it difficult to break down in the gastrointestinal tract. It is classified as an antinutrient because it can interfere with the absorption of biotin, a vital nutrient involved in various metabolic processes in the body. When avidin binds to biotin, it prevents biotin from being absorbed in the intestine, leading to potential biotin deficiency if consumed in excessive amounts.

   Despite its potential drawbacks, avidin also has practical applications. Its strong interaction with biotin has been harnessed for a wide range of biological research techniques, such as affinity chromatography and in vitro diagnostics. Moreover, avidin is often used as a biotechnological tool due to its ability to specifically bind with biotinylated molecules, facilitating various labeling and targeting methods.

   In conclusion, avidin is a protein found in raw egg whites that strongly binds with biotin. While it can hinder biotin absorption in excessive amounts, its affinity for biotin has also found important applications in biological research and biotechnology.

Etymology of AVIDIN

The word "avidin" comes from the Latin word "avīdus", which means "eager" or "greedy". It was coined by scientists in the early 20th century as they discovered a protein in egg whites that had a strong affinity for biotin, a B-vitamin. The protein was found to avidly bind to biotin, hence leading to the name "avidin".
