Sucrose, a disaccharide, is a sugar composed of glucose and fructose subunits. It is produced naturally in plants and is the main constituent of white sugar. It has the molecular formula C. 12H. 22O. 11 . For human consumption, sucrose is extracted and refined from either sugarcane or sugar beet.
Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides ). The most common types of disaccharides—sucrose, lactose, and maltose—have 12 carbon atoms, with the general formula C 12 H 22 O 11. The differences in these disaccharides are due to atomic ...
Sucrase. Sucrases are digestive enzymes that catalyze the hydrolysis of sucrose to its component monosaccharides, fructose and glucose. One form, sucrase-isomaltase, is secreted in the small intestine on the brush border. [ 1] The enzyme invertase, which occurs more commonly in plants, fungi and bacteria, also hydrolyzes sucrose (and other ...
Lactose, maltose, and sucrose are all compound sugars, disaccharides, with the general formula C 12 H 22 O 11. They are formed by the combination of two monosaccharide molecules with the exclusion of a molecule of water. [72] Lactose is the naturally occurring sugar found in milk. A molecule of lactose is formed by the combination of a molecule ...
The chemical formula of iron sucrose is C 12 H 29 Fe 5 Na 2 O 23. The iron sucrose molecule is a polymer with two main molecules; sucrose (chemical formula C 12 H 22 O 11) and an iron (III) hydroxide (Na 2 Fe 5 O 8 •3 (H 2 O)). These two components are in solution together, but are not bound to one another. [ 2]
White sugar. A bowl of white sugar. White sugar, also called table sugar, granulated sugar, or regular sugar, is a commonly used type of sugar, made either of beet sugar or cane sugar, which has undergone a refining process. It is nearly pure sucrose .
High-fructose corn syrup. High-fructose corn syrup ( HFCS ), also known as glucose–fructose, isoglucose and glucose–fructose syrup, [ 1][ 2] is a sweetener made from corn starch. As in the production of conventional corn syrup, the starch is broken down into glucose by enzymes. To make HFCS, the corn syrup is further processed by D-xylose ...
A reducing sugar is any sugar that is capable of acting as a reducing agent. [ 1] In an alkaline solution, a reducing sugar forms some aldehyde or ketone, which allows it to act as a reducing agent, for example in Benedict's reagent. In such a reaction, the sugar becomes a carboxylic acid . All monosaccharides are reducing sugars, along with ...
