Study Notes

Biochemistry Course: Lecture 1 - Functional Groups

The lecture covers functional groups, their structures, reactions, and their role in medicine.
The presenter is Dr. Shona Pedersen, an associate professor in biochemistry at Qatar University.

Learning Styles

Understand your learning style (visual, kinesthetic, auditory) to tailor note-taking.
Prepare notes according to your learning style.
Review your notes the same day as the lecture.
Review notes again within 2-3 days and before the next lecture.

What is Biochemistry?

Biochemistry bridges the gap between biology and chemistry.
Biochemistry studies the chemical processes that happen in living organisms.
It uses knowledge from chemistry to understand biological processes.
The components of living things are: life, organisms, cells, reactions, molecules, and atoms.

Importance of Biochemistry in Medicine

Biochemistry is crucial to medicine, as advancements in the field are related to understanding biochemical changes.
Biochemical changes in the body, caused by infection or disease, are studied to diagnose and treat patients.

Levels of Understanding in Biochemistry (BIOM201)

The course covers biochemistry from basic to advanced levels.
Examples illustrate different levels of understanding
Basic examples: Chemistry of main molecules of life
Intermediate examples: Main biochemical reactions in the human cell
Advanced examples: Electron tunneling in the respiratory chain

Nobel Prize Chemists

Professor Sir Geoffrey Wilkinson: Nobel Prize 1973 for Organometallic Catalysis ('Wilkinson catalyst').
Professor Sir Derek Barton: Nobel Prize 1969 for 3D conformation of organic molecules ('Barton reaction').

Cells

Cells are composed of peptides, proteins, sugars & carbohydrates, lipids & fats, nucleic acids (DNA & RNA), and metabolites.
Carbon is the most common element in major macromolecules in a cell, making up about 18.5% of human atoms.

Hydrocarbons

Hydrocarbons (HCs) consist solely of carbon and hydrogen.
Many organic molecules, such as fats, contain hydrocarbon components.
HCs undergo reactions that release large amounts of energy.
HCs are classified into alkanes, cycloalkanes, alkenes, alkynes, and aromatics.
Alkanes have only single bonds. Alkenes have at least one double bond, and alkynes have at least one triple bond.

IUPAC

The International Union of Pure and Applied Chemistry (IUPAC) provides a system for uniformly naming organic compounds.
This system ensures uniqueness and unambiguous naming of organic compounds to avoid confusion or errors.
Prefixes (e.g., meth-, eth-, prop-) are used to indicate the number of carbon atoms in the chain of an alkane.

Aldehydes and Ketones, Alcohols and Phenols

The lecture covers the structure, function, and importance of these functional groups in biochemistry and medicine.
Aldehydes and ketones contain a carbonyl group (C=O).
Alcohols contain a hydroxyl group (-OH). Phenols have a hydroxyl group attached to an aromatic ring.
Different structures and reactions are discussed from simple to more complex structures, particularly in relation to drugs and their naming systems.

Aldehydes (-al)

Aldehydes have at least one hydrogen attached to the carbonyl group.
Various examples and IUPAC nomenclature (including double bonds and substituents) are provided.
Medical and biomedical uses (e.g., as solvents, perfume ingredients, dyes, preservatives, and in physiological processes like vision) are mentioned.

Ketones (-one)

Ketones have two carbon atoms attached to the carbonyl group and no hydrogens.
Examples and IUPAC nomenclature (including double bonds and substituents) are discussed.
Medical and biomedical applications—including their presence in the human body (e.g., hormones, skin treatments) and potential medical implications—are described.

Alcohols

Alcohols contain a hydroxyl group (-OH), and have various types of structures (e.g., simple to those with multiple hydroxyl groups).
Naming and IUPAC conventions for alcohols are covered, including cases with multiple hydroxyl groups (e.g., ethylene glycol, glycerol).
Chemical reactions and medical uses (e.g., solvents, antifreeze, and components of pharmaceuticals) are included.

Phenols

Phenols contain a hydroxyl group attached to an aromatic ring.
Properties (e.g., polarity, solubility) and medical/biological applications (e.g., disinfectants) are outlined.

Reactions of Aldehydes, Ketones, Alcohols, and Other Functional Groups

Oxidation and reduction reactions are fundamental in the study of these compounds.
Oxidation leads to an increase in oxygen atoms or a loss of hydrogen atoms, whereas reduction is the opposite.
Chemical reactions of these groups are studied to understand their processes and functions.

Importance of Learning Functional Groups

Understanding functional groups is vital in organic chemistry and biochemistry.
This knowledge is essential to classify compounds, predict their properties and behaviour, and explain their role in various biological and chemical processes.

Additional Information

The different ways compounds react with each other.
Types of reactions for aldehydes, ketones, alcohols, and phenols, like esterification.
