What are aldehydes and ketones?
What are aldehydes and ketones?
A class of organic compounds containing a carbonyl group (C=O) and an -OH group attached to the same carbon atom. Aldehydes are characterized by having the carbonyl group at the end of a carbon chain, while ketones have the carbonyl group within the chain.
What is condensation reaction?
What is condensation reaction?
A type of chemical reaction where two or more molecules combine to form a larger molecule, often with the elimination of a small molecule such as water. In the context of carbohydrates, this reaction is crucial for the formation of polysaccharides from monosaccharides.
What is hydrolysis reaction?
What is hydrolysis reaction?
A type of chemical reaction where a large molecule is broken down into smaller molecules using water. In the context of carbohydrates, this reaction breaks down polysaccharides into monosaccharides.

Study Notes
Carbohydrate Chemistry - Year 1 Biochemistry Lecture
- This lecture covers carbohydrate chemistry, specifically for first-year medical students at Helwan National University.
- The academic year is 2024-2025, Semester 1, Module 1 (Human Body Function - HBF-102).
- The lecturer is Professor Dr. Mohamed I. Kotb and Associate Professor Dr. Ahmed M. A. Akabawy, both from the Biochemistry & Molecular Biology Department, Faculty of Pharmacy, Helwan University.
Objectives
- Define carbohydrates and their biological importance.
- Classify carbohydrates.
- Define, classify, and describe the structural composition of monosaccharides with examples.
- Understand the biological importance of monosaccharides.
- Define isomerism and different forms with examples.
- List monosaccharide derivatives.
Introduction to Carbohydrates
- Carbohydrates are the most abundant organic biomolecules in nature.
- They are composed of carbon, hydrogen, and oxygen (CHO).
- Carbohydrates include monosaccharides, disaccharides, oligosaccharides, and polysaccharides.
Classification of Carbohydrates
- Monosaccharides: cannot be hydrolyzed into simpler units. Examples include glucose, fructose, galactose.
- Disaccharides: form two monosaccharide units through hydrolysis. Examples include maltose, sucrose, lactose.
- Oligosaccharides: contain three to ten monosaccharide units, formed by hydrolysis.
- Polysaccharides: have more than 10 monosaccharide units and are large, complex molecules, formed by hydrolysis. Examples include starch, glycogen, cellulose.
Monosaccharides: Structure
- D-glucose is the most important natural monosaccharide.
- It's an aliphatic aldehyde with six carbon atoms, five carrying hydroxyl groups.
- Monosaccharides exist in both open-chain and ring forms.
- They are categorized as either aldoses (aldehyde functional group) or ketoses (ketone functional group) based on their carbonyl group.
- Different forms (a and ß) of monosaccharides are diastereomers, not enantiomers because they are not mirror images of each other.
Isomerism
- Isomers are compounds with the same molecular formula but different structural arrangements.
- Types of isomerism include structural isomerism (different arrangement of atoms) and stereoisomerism (same atomic arrangement but different spatial arrangement).
- Stereoisomers include enantiomers, diastereomers, epimers, and anomers.
- Enantiomers: are non-superimposable mirror images of each other.
- Diastereomers: are stereoisomers that are not mirror images.
- Epimers: are a specific type of diastereomers that differ in the configuration around only one chiral carbon atom.
- Anomers: are a specific type of stereoisomers that differ in the configuration around the hemiacetal or hemiketal carbon.
- Chirality refers to molecules that lack a plane of symmetry (optical activity).
Classification of Monosaccharides
- Monosaccharides are categorized by the number of carbon atoms (triose, tetrose, pentose, hexose).
- Specific examples of each type of monosaccharides (e.g., glyceraldehyde (a triose), erythrose (a tetrose)).
- Specific examples of pentose monosaccharides (ribose, xylose).
- Specific examples of hexose monosaccharides (glucose, fructose, galactose, mannose).
Biological Importance of Monosaccharides
- Glucose: major energy source for mammals.
- Fructose: important energy source, especially for sperm.
- Galactose: converted to glucose in the liver, part of lactose (milk sugar).
- Mannose: part of many glycoproteins.
- Pentoses (ribose and deoxyribose): crucial components of RNA, DNA, ATP, GTP and coenzymes.
Monosaccharide Derivatives
- Deoxy sugars: have a hydrogen atom replacing a hydroxyl group. Examples include 2-deoxy-D-ribose.
- Sugar alcohols: have a reduced carbonyl group. Examples include glycerol and ribitol.
- Sugar acids: have an oxidized carbonyl group. Examples include gluconate.
- Amino sugars: have an amino group which can be further acetylated. Examples include glucosamine.
Anomeric Carbon and Mutarotation
- The anomeric carbon is the new chiral center formed during cyclization.
- Mutarotation reflects the equilibrium between a and β anomers of a sugar in solution.
Enzymes and Isomerism
- Enzymes can distinguish between the different arrangements of atoms in isomers and use one arrangement preferentially for specific processes.
Interactive Questions
- Questions related to general formula, examples of optical isomerism, types of monosaccharides, and their significance are included.
