Trehalose (or mycose) is a disaccharide composed of two glucose residues. The glucose residues are linked by an α 1→4 glycosidic bond.

Trehalose in cosmetic preparation?

Trehalose is a sugar which is found actually in cactus plants. It is this sugar which protects cactus from drying in deserts and retaining water as trehalose has a property of retaining water. This ingredient is used in cosmetics preparation for dry skin. Trehalose protects dry skin and retains moisture of the skin.


Why trihalose deos not give seliwanoff'?

Trehalose does not give a positive test with Seliwanoff's reagent because trehalose is a non-reducing sugar. Seliwanoff's reagent reacts with ketoses to form a red color, but since trehalose contains two glucose units linked by an α,α-1,1-glycosidic bond, it does not have a free ketone or aldehyde group necessary for the reaction with Seliwanoff's reagent.

What are the names of two non-reducing sugars?

Two examples of non-reducing sugars are sucrose and trehalose. These sugars do not have a free anomeric carbon that can undergo mutarotation and therefore do not react with Benedict's or Fehling's solution.


When 2 glucose molecules are combined what is formed?

Maltose, Trehalose and Cellobiose are all formed solely from glucose molecules. Less common disaccharides of glucose include: Kojibiose, Nigerose, Isomaltose, β,β-Trehalose, α,β-Trehalose, Sophorose, Laminaribiose and Gentiobiose.

Two monosaccharides in trehalose?

As you look at the structural formula of Trehalose, look to the left side of it. Depending how it's drawn convert just that side to a Haworth projection to make it easier. Then turn that into a monosacharide. A monosaccharide has a C=O or HC=O right? "can't be hydrolized to a simpler compound" but i like to think of easier terms. Cn H2n On is the basic formula. once you have your haworth projection drawn take of the OH on Carbon number 1 to turn it to a monosaccharide. and draw it out in the Fischer projection. Then pull out your handy dandy table (should be in your book) on the names of them. and if you match the picture correctly you should get GLUCOSE now the second one. Repeat the steps. now the second one is upside down which is a bit tricky, but you can see that it is also GLUCOSE THE FINAL ANSWER: Trehalose conists of 2 glucose monosaccharide units.
