Carbohydrate Chemistry - Year 1
- Academic Year: 2024-2025
- Semester: 1
- Module: Human Body Function (HBF-102)
- Course: Biochemistry
- Institution: Helwan National University
- Faculty: Faculty of Medicine
- Lecturer: Prof. Dr. Mohamed I. Kotb & Assoc. Prof. Dr. Ahmed M.A. Akabawy
- Department: Biochemistry & Molecular Biology
Objectives
- Define carbohydrates and list their biological importance
- Classify carbohydrates
- Define, categorize, and describe the structural composition of monosaccharides with examples
- Explain the significant biological properties of monosaccharides
- Define isomerism and list types with examples
- Create a list of monosaccharide derivatives
Introduction
- Carbohydrates are the most abundant biomolecules in nature.
- Carbohydrates comprise monosaccharides, disaccharides, oligosaccharides, and polysaccarides.
Classification of Carbohydrates
- Monosaccharides: These cannot be broken down into simpler sugars by hydrolysis. Examples include glucose, fructose, and galactose.
- Disaccharides: Formed by the combination of two monosaccharides through a glycosidic bond. Examples include lactose and sucrose.
- Oligosaccharides: Composed of three to ten monosaccharides linked together via glycosidic bonds.
- Polysaccharides: Composed of more than ten monosaccharides, these serve various functions in the body. Examples include starch and glycogen.
Classification of Monosaccharides
-
Trioses: 3 carbon atoms
-
Tetroses: 4 carbon atoms
-
Pentoses: 5 carbon atoms
-
Hexoses: 6 carbon atoms
-
Aldoses: Contain an aldehyde group (-CHO)
-
Ketoses: Contain a ketone group (-C=O)
Monosaccharides: Structure
- The most important natural monosaccharide is D-glucose.
- It's an aliphatic aldehyde with six carbon atoms, five of which bear hydroxyl groups.
- It exists in both open-chain and cyclic forms.
- Monosaccharides, like glucose, can exist in different ring forms (pyranose and furanose)
Medical and Biological Importance of CHO
- Serve as energy sources and stores.
- Are components of several animal and plant structures.
- Act as cell membrane components.
- Participate in intercellular communication.
- Are parts of DNA and RNA structures.
- Are found in various drugs.
- Are components of complex lipids and proteins.
- Lactose is a crucial milk sugar.
- Metabolic disorders related to CHO can impact human health, exemplified by diabetes mellitus, galactosemia, and lactose intolerance.
Isomerism
- Stereoisomers are compounds with the same molecular formula but differ in the spatial arrangement of their atoms.
- Structural isomers differ in the bonding sequence of carbon atoms.
- Stereoisomers include enantiomers and diasteroisomers.
- Enantiomers are non-superimposable mirror images of each other.
- Diastereomers are stereoisomers that are not mirror images.
- Epimers are a specific type of diastereomer that differ in the configuration around only one specific chiral carbon.
- Anomers are a specific type of epimerism relating to glucose where the configuration differs around the anomeric carbon. Anomeric carbons are carbons, typically 1, in the ring structures of monosaccharides.
Optical Isomerism
- Optical activity is the capacity of a substance to rotate plane-polarized light.
- Chiral molecules rotate plane-polarized light.
Mutarotation
- The process by which the cyclic form of a sugar changes between its a and b anomers in solution.
- The conversion is a spontaneous equilibrium process.
Monosaccharide Derivatives
- Sugar phosphates
- Deoxy sugars (e.g., 2-deoxy-D-ribose)
- Amino sugars (e.g., glucosamine)
- Sugar alcohols (e.g., glycerol, ribitol)
- Sugar acids (e.g., glucuronic acid)
Enzymes and Isomerism
- Enzymes distinguish between the isomers of glucose and other sugars to perform metabolic processes.
- This selectivity determines which structural forms of sugars are preferentially utilized and synthesized by enzymes.
Interactive Questions
- General formula of carbohydrates?
- Example of optical isomerism in carbohydrates?
- Example of a ketose sugar
- Monosaccharide component of RNA
- What is the anomeric carbon and importance?
