NCERT Solutions Class 12 Chemistry Chapter 14 Biomolecules

Chemicals make up life, and living organisms are made up of biomolecules, including carbohydrates, vitamins, lipids, proteins, and nucleic acids. The molecular logic of life processes is made up of these biomolecules interacting with one another. In addition, essential compounds such as vitamins and mineral salts play a vital part in how organisms function. NCERT Solutions Class 12 Chemistry Chapter 14 discusses and answers the structures and functions of some of these biomolecules.

After studying with Extramarks’ Solutions, students will be able to:

  • Comprehend the characteristics of biomolecules such as carbohydrates, proteins, nucleic acids, and hormones and classify carbohydrates, proteins, nucleic acids, and vitamins based on their structures.
  • Differentiate between DNA and RNA.
  • Understand the role of biomolecules in biosystems.

NCERT Solutions Class 12 Chemistry Chapter 14 covers questions and solutions on commonly heard and somewhat unusual biomolecules, such as glycogen, cellulose, saccharides, etc.

These answers are written in primary language to make them easier for students to understand. On Extramarks’ official website, you can get free access to NCERT Solutions Class 12 Chemistry Chapter 14, curated by Extramarks subject experts.

FAQs (Frequently Asked Questions)

It is necessary to read the Chapter to comprehend what it offers fully. While reading the chapter, students should quickly note all the significant points to access them during the Examination. To answer any question from this Chapter, students should regularly practice the numerous names, formulae, and functions. Aside from that, students must consult Extramarks Chapter 14 Class 12 Chemistry NCERT Solutions and complete all the included activities.

  1. Glucose has the following properties:
  • Pentaacetate is produced when glucose is acetylated with acetic anhydride, confirming the presence of hydroxyl groups in glucose.
  • When glucose reacts with hydroxylamine, it produces monoxime, which combines with a molecule of hydrogen cyanide to form cyanohydrin. This proves that glucose has a carbonyl group.
  • Glucose is oxidised to gluconic acid when it reacts with weak oxidising agents like bromine water. On the other hand, when nitric acid is oxidised, saccharic acid is generated.

Carbohydrates are stored in the form of glycogen, a polysaccharide in animals. Similarly, amylose and amylopectin are the two components of starch. Even though starch and glycogen are carbohydrates, glycogen only has an element. When opposed to amylopectin, glycogen has a more branched structure. Class 12 students can better comprehend these concepts by studying the NCERT Solutions created by Extramarks experts.

  1. Monosaccharides are carbohydrate molecules that cannot be further broken down (hydrolysed) into ketones or units of polyhydroxy aldehyde. The functional group and number of carbon atoms in these monosaccharides can be used to Classify them further.

 

  • Functional Groups-Based Classification:

The monosaccharides that contain a keto-group are Classified as ketoses, whereas those containing aldehyde groups are called aldoses.

 

  • Classification Based on the Number of Carbon Atoms:

Monosaccharides are Classified as trioses, pentoses, tetroses, or heptoses based on the number of carbon atoms present.

The monosaccharides are named after the two classes mentioned above. For example, aldotetrose is an aldose with four carbon atoms, while ketotetrose is a ketose with four carbon atoms.

  1. Biomolecules are organic compounds that have a role in various metabolic activities such as cell repair, digestion, and growth. These biomolecules support all of the living activities required for human survival. 

Biomolecules are divided into four categories: 

  • Lipids
  • Proteins
  • Nucleic acids
  • Carbohydrates. 

Besides  these, a slew of biomolecules plays a role in metabolic processes.
