Pronunciation: [mˈana͡ɪd] (IPA) 
The word "Mannide" is spelled with two n's and an i despite the sound being a long a sound. This is due to the fact that the word comes from the chemical compound mannitol, which is spelled with two n's and an i. Therefore, when the suffix -ide is added to mannitol, the spelling remains the same. The IPA transcription of this word is /ˈmæn.aɪd/, where the dot represents a schwa sound, and the i represents a long a sound.
Mannide is a term primarily used in chemistry to describe a type of organic compound that belongs to the family of compounds known as sugars or sugar alcohols. Specifically, mannide refers to an alcohol derivative of mannose, a hexose sugar. Mannose is most commonly found in the form of the natural D-isomer, which is the biologically active form.
Mannide possesses a characteristic structure in which the carbon atom 6 of mannose is reduced to an alcohol group, resulting in the formation of mannitol. Mannide compounds can exist in either the D- or L-form, depending on the configuration of the hydroxyl groups around the asymmetric carbon atoms.
Due to their unique structural properties, mannides find applications in various industries. In the food and pharmaceutical industries, mannides are often utilized as artificial sweeteners or sugar substitutes due to their sweet taste and low calorie content. These compounds also possess humectant properties, making them suitable for use as stabilizers and moisture-retaining agents in food products.
In addition, mannide compounds have been studied for their potential role in medical treatments. Research has shown that certain mannide derivatives possess antioxidant and anti-inflammatory properties, making them promising candidates in the development of drugs for the treatment of various diseases.
Overall, mannide refers to a sugar alcohol derivative of mannose, possessing unique properties and potential applications in the fields of food science, pharmaceuticals, and medicine.
