Structural Comparison between Sucrose and Trehalose in

Sucrose and trehalose are both disaccharide molecules with the same chemical formula (C 12 H 22 O 11) but with different geometrical structures (see Figure 1) The sucrose molecule consists of one glucose ring and one fructose ring connected by a glycosidic linkage whereas the trehalose molecule consists of two glycosidic-linked glucose rings Both sucrose and trehalose are often used as a

Sucrose

Because sugars contain many hydroxyl groups glycosidic bonds can join one monosaccharide to another Oligosaccharides are built by the linkage of two or more monosaccharides by O-glycosidic bonds (Figure 11 10) In maltose for example two d-glucose residues are joined by a glycosidic linkage between the α-anomeric form of C-1 on one sugar and the hydroxyl oxygen atom on C-4 of the adjacent

What does alpha acetal linkage mean? + Example

An alpha acetal linkage is a glycoside linkage that points in the opposite direction to the CH_2OH group Let's begin by defining terms An acetal is a functional group formed when an aldehyde reacts with an alcohol to form a functional group with two ether groups on the same carbon The term alpha acetal usually refers to carbohydrates and their derivatives

Trehalose has a much more static structure than the reducing sugars due to its lack of mutarotation or the other common non-reducing disaccharide sucrose due to its lack of a furan ring its two symmetrically-linked glucose units being joined by a very stable glycosidic linkage that is far more stable than the labile β-D-fructofuranoside linkage in sucrose
