The formation of osazone from glucose or lactose can take a few minutes to hours, depending on the reaction conditions. This process involves the reaction of glucose or lactose with excess phenylhydrazine in the presence of an acid catalyst. The resulting osazone crystals are then typically observed under a microscope for identification.
What else can I help you with?
Is lactose a polymer or a mineral?
Lactose is neither a polymer nor a mineral. It's not a mineral because it's an organic compound usually found in living things. It's not a polymer because it's not a long chain molecule, just a disaccharide formed from galactose and glucose.
Seeds can store glucose in the form of?
Seeds can store glucose in the form of starch, which serves as a source of energy for the germinating seedling. Starch is a complex carbohydrate made up of a long chain of glucose molecules that can be broken down into glucose when needed for energy.
What is the storage molecule made by glucose in plants?
Starch. Plants use the excess glucose to form starch molecules
What chemical reaction forms cellulose?
Cellulose is formed through a condensation reaction between glucose molecules, where a hydroxyl group from one glucose molecule combines with a hydrogen atom from another glucose molecule to form a water molecule. This bonding process repeats to form long chains of glucose molecules, which then arrange themselves into the fibrous structure of cellulose.
What molecules join in long chains to make cellulose?
Glucose molecules join together in long chains to make cellulose. Multiple glucose molecules are linked by beta (1-4) glycosidic bonds to form the cellulose polymer.
What does heating cause to lactose in milk to do?
Lactose is a sugar like glucose or fructose and so cannot be denatured as can enzymes, which are proteins. However, if you heat lactose long enough it will caramelize (oxidize), like the sugar in sweetened condensed milk does when super heated.Heating lactose-free milk does denature the enzyme it contains to digest lactose, lactase, and inhibit it from working further.
What is mono-di and polysaccharides?
Monosaccharides are simple sugars which are made of a single sugar molecule eg glucose, lactose, fructose.Disaccharides are double sugars, formed from two monosaccharides linked together by a chemical bond (a glycosidic bond) eg lactose (milk sugar) consists of glucose and galactose combined together.Polysaccharides ("many" sugars) are made of many (eg hundreds) monosaccharides linked together by glycosidic bonds eg starch and cellulose are made from glucose molecules linked to form long chains.Read more: What_is_mono-di_and_polysaccharides
What organ modifies sugar?
There are many types of sugar. Fructose, Lactose, Galactose, Sucrose, Long Chain Carbohydrates, etc. Your brain, muscles, and the rest of the body like Glucose. Different sugars are converted to Glucose in the Liver.
What is di polysaccharide?
Monosaccharides are simple sugars which are made of a single sugar molecule eg glucose, lactose, fructose. Disaccharides are double sugars, formed from two monosaccharides linked together by a chemical bond (a glycosidic bond) eg lactose (milk sugar) consists of glucose and galactose combined together. Polysaccharides ("many" sugars) are made of many (eg hundreds) monosaccharides linked together by glycosidic bonds eg starch and cellulose are made from glucose molecules linked to form long chains.
What molecules link together to form starch?
glucose glucose units come together to form large cellulose and starch molecules.
Is lactose a polymer or a mineral?
Lactose is neither a polymer nor a mineral. It's not a mineral because it's an organic compound usually found in living things. It's not a polymer because it's not a long chain molecule, just a disaccharide formed from galactose and glucose.

This bonding process repeats to form long chains of glucose molecules, which then arrange themselves into the fibrous structure of cellulose.
Glucose in roots is stored in what form?
Glucose in roots is stored in the form of starch. Starch is a polysaccharide composed of many glucose molecules linked together in a branched structure. Roots accumulate starch as a long-term energy reserve that can be broken down into glucose when needed for energy.
What subunits make up poly-carbohydrates?
Carbohydrates are made up of glucose subunits . In complex carbohydrates long polymer chains of glucose subunits form the higher structure, they can be "nibbled" from either end by digestion enzymes. The breakdown into glucose is needed for metabolism. Sugar units are called saccharides in chemistry. Starch and cellulose are polysaccharides made from glucose. The difference in starch and cellulose is the manner in which the glucose units are bonded. Humans do not have the enzymes to digest cellulose. Simple sugars consits of small clusters of glucose, fructose and glactose subunits, amongst others that are all structually similar. Lactose found in milk is a carbohydrate sugar made from a glucose and galactose subunit.
What is the simplest form a starch can be broken down into?
The simplest form a starch can be broken down into is glucose. Starch is a polysaccharide made up of long chains of glucose molecules, and during digestion or enzymatic breakdown, these chains are hydrolyzed into individual glucose units. Glucose then serves as a primary source of energy for cells in the body.
