Which of the following is not a disaccharides?

So, the correct answer is option (D) starch.

What are the 3 disaccharides?

The three major disaccharides are sucrose, lactose, and maltose. Sucrose, which is formed following photosynthesis in green plants, consists of one molecule of glucose and one of fructose bonded via an α-,β-linkage.

Which of the following is a disaccharide?

Disaccharide Common name Monosaccharides
Sucrose Table sugar Glucose-fructose
Lactose Milk sugar Galactose-glucose
Maltose Malt sugar Glucose-glucose
Isomaltose Glucose-glucose

What are 4 disaccharides?

Three common examples are sucrose, lactose, and maltose. Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides).

Common disaccharides.
Disaccharide Cellobiose
Unit 1 Glucose
Unit 2 Glucose
Bond β(1→4)

What are 5 examples of disaccharides?

Sucrose, maltose, and lactose are the most familiar disaccharides, but there are others.
  • Sucrose (saccharose) glucose + fructose. Sucrose is table sugar. …
  • Maltose. glucose + glucose. Maltose is a sugar found in some cereals and candies. …
  • Lactose. galactose + glucose. …
  • Cellobiose. glucose + glucose.

Is amylose a disaccharide?

Starch consists of two types of polysaccharides: amylose and amylopectin. Amylose is a straight linear chain of glucose molecules linked by α-l,4 glycosidic linkages as shown in Fig. 2.19, in the same manner as in the disaccharide maltose. … Amylose is water insoluble and constitutes about 20% of starch.

What are 3 polysaccharides examples?

Sometimes known as glycans, there are three common and principal types of polysaccharide, cellulose, starch and glycogen, all made by joining together molecules of glucose in different ways.

Is starch a disaccharide?

Carbohydrates are classified into four categories: simple sugars or monosaccharides, such as glucose and fructose, disaccharides, such as sucrose and lactose, oligosaccharides, such as maltodextrin and dextrins, and polysaccharides, such as starches and cellulose.

Is an example of disaccharide present in?

Sucrose. Sucrose, commonly known as table sugar in its refined form, is a disaccharide found in many plants. It is made up of the monosaccharides glucose and fructose. In the form of sugar, sucrose is a very important component of the human diet as a sweetener.

What are the 4 main polysaccharides?

Types Of Polysaccharides
  • Glycogen: It is made up of a large chain of molecules. …
  • Cellulose: The cell wall of the plants is made up of cellulose. …
  • Starch: It is formed by the condensation of amylose and amylopectin. …
  • Inulin: It is made up of a number of fructofuranose molecules linked together in chains.

Which of the following is not a polysaccharide?

Complete answer: a) Sucrose – Sucrose is a type of disaccharide. Disaccharides are compounds made up of two monosaccharides. Sucrose is made up of two monosaccharides that are glucose and fructose.

Is chitin a polysaccharide?

Chitin is the most abundant aminopolysaccharide polymer occurring in nature, and is the building material that gives strength to the exoskeletons of crustaceans, insects, and the cell walls of fungi.

What is a type of indigestible polysaccharide?

These indigestible polysaccharides are often called dietary fiber. The typical dietary fiber includes cellulose, hemicellulose, β-glucan, pectin, mucilage, gums and lignin.

What are the 4 polysaccharides and their functions?

The main functions of polysaccharides are structural support, energy storage, and cellular communication. Examples of polysaccharides include cellulose, chitin, glycogen, starch, and hyaluronic acid.

What are the 4 organic elements that make macromolecules?

There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).

Which of the following polysaccharides Cannot be digested by mammalian salivary?

Cellulose is a glucose polymer connected by β-1,4 linkages, which cannot be digested by mammalian enzymes.

What polysaccharide Cannot be digested by animals?

Cellulose is a polymer made with repeated glucose units bonded together by beta-linkages. Humans and many animals lack an enzyme to break the beta-linkages, so they do not digest cellulose.

Which polysaccharides are digestible and which are not?

Although available starch is readily digested in the small intestine, resistant starch (RS) and cell wall polysaccharides (or nonstarch polysaccharides, NSPs) are not digested, but are the major components of dietary fiber and are fermented by the colon microbiota to produce short chain fatty acids (SCFAs).

Which of the following disaccharides Cannot be digested by mammals?

Mammals use the enzyme lactase to digest lactose. Sucrose is a disaccharide formed from one glucose and one fructose molecule. Mammals use the enzyme sucrase to digest sucrose. Mammals cannot digest cellulose because they do not have the necessary enzymes to do so in their digestive tracts.

Which of the following Cannot be digested?

Hence, the correct answer for this question is B, i.e. Cellulose.
