How are sugars, such as fructose and lactose, classified?
Sugars like fructose and lactose are classified as carbohydrates, specifically as simple sugars or monosaccharides (fructose) and disaccharides (lactose).
What do monosaccharides combine to make?
Monosaccharides combine to make disaccharides or polysaccharides through a dehydration synthesis reaction, where a water molecule is released. Examples of disaccharides include sucrose (glucose + fructose) and lactose (glucose + galactose). Examples of polysaccharides include starch, glycogen, and cellulose.
What chemical reaction does lactase catalyze?
Lactase catalyzes the hydrolysis of lactose, a disaccharide found in milk, into its constituent monosaccharides, glucose and galactose. This enzymatic reaction allows for the digestion and absorption of lactose in the small intestine.
What is the combination of glucose and galactose?
The combination of glucose and galactose forms lactose, which is a disaccharide commonly found in milk. Lactose is broken down by the enzyme lactase into its constituent monosaccharides during digestion.
What forms when two monosaccharides link together?
When two monosaccharides link together by Glycosidic bond (type of covalent bond formed by sugar molecule with others) they form a disaccharide. Example of disaccharides: Sucrose - glucose + Fructose Lactose - Galasctose + Glucose
What monosaccharides are in milk?
lactose
What two molecules make lactose?
Glucose and Galactose make up lactose Glucose and fructose make up sucrose Glucose and glucose make maltose
What two monosaccharides make up milk sugar?
The 2 mono saccharides that make up lactose are glucose and galactose. Glucose is basically sugar in its most basic form. It is made by plants through photosynthesis.
What two monosaccharides forms lactose?
Glucose and Galactose.
Is lactose an aldose?
yes, because it's made up of glucose and galactose. These 2 sugars are monosaccharides that have an aldehyde at their C1 end in their linear form, thus they're both aldoses. Therefore lactose is an aldose. Lactose is also a reducing sugar, and both glucose and galactose that make up lactose are hexoses (6-membered sugar rings).
How are starches and monosaccharides related?
starches and monosaccharides are carbohydrates, and monosaccharides make up starches, which is a polysaccharide.
What is the chemical make up of monosaccharides?
The general formula of monosaccharides is C6H12O6.
Is lactose a polysaccharide or a disaccharide?
Lactose is a disaccharide composed of two monosaccharides, glucose and galactose, linked together.
How are sugars, such as fructose and lactose, classified?
Sugars like fructose and lactose are classified as carbohydrates, specifically as simple sugars or monosaccharides (fructose) and disaccharides (lactose).
The subunits that make up polysaccharides are?
The subunits that make up polysaccharides are sugars, or monosaccharides. An example of a monosaccharide is glucose, which we need for energy.
What is the make up of polysaccharides?
monosaccharides
Why doesnt the lactase in lactose intolerant people work?
Lactose intolerant people have a deficiency of an enzyme called lactase, which breaks up the lactose into two monosaccharides called galactose and glucose. These two are easily digestable, whereas lactose is not.
