BiochemistryMoisés Sánchez Gómez & Javier Hernandez Puchot
What it studies?
It studies the processes of the living things
All the sciences that are related to life are linked to biochemistry
It once was generally believed that life and its materials had some essential property or substance
Many years ago, the scientist thought that living things could only produce certain substances.
Friedrich Wöhler
Friedrich Wöhler in 1828, he synthesized the urea and published a book where he had the evidence that organic compounds could be synthesized.
QUICK QUESTION!!
• Who was Friedrich Wöhler?
Main classes of molecules
• carbohydrates• lipids• Proteins• nucleic acids
Monomers and polymers
Monomers are microscopic molecules that they link to make larger chains named polymers
The monomers when they are linked they can synthesis biological polymers.
Monomers make different chains, depending on the function they are needed
Examples of monomers
• monosaccharides• glycerol and fatty acids• nucleotides• amino acids
QUICK QUESTION!!!
• Name the main clases of molecules. (4)
Monosaccharides
Monosaccharides link to make carbohydrates and carbohydrates are used to provide energy to a organism.
Glycerol and fatty acids
Glycerol and fatty acids link to make lipids. Lipids are use as energy providers and in cell membranes Some lipids are bad, others are good
Nucleotides
Nucleotides link to make DNA and RNA. The DNA gives mthe instruction of how to make the poby and its functions, the RNA is for making copies of DNA.
Quick QUESTION!!!• Does Glycerol and fatty acids link to make Proteins? (true or false)
Aminoacids
• Aminoacids are organic compounds made up of amine which is (-NH2) and carboxylic acid (-COOH).
• The main elements of an aminoacid are H, C, O and N.
Carbohydrates
• A carbohydrates is a molecule that contains H, O and C.
• And is a synonym of a saccharide.
Lipids
• A lipid is an organic compound that their solubility is in organic solvents (like acetone, chloroform, etc) and also in wáter.
QUICK QUESTION!!!
• What is BIO CHEMISTRY?
Proteins
• They are molecules or “macromolecules” that consist in a chain of aminoacid residues.• They function in the metabolic reactions, replicating DNA, etc.
