Proteins (A) Flashcards
What are proteins?
The polymers of amino acids
What elements do proteins contain?
Carbon
Hydrogen
Oxygen
Nitrogen
Sulphur
Do all amino acids have the same general structure?
Yes
What are amino acids?
The sub-units from which proteins are made from
monomers –> polymers
What are the similarities and differences between every amino acid?
They all have an amine group (NH₂), a carboxylic acid group (COOH) and a hydrogen atom (H)
Though the R group differs for each one
What are amino acids joined together by?
Peptide bonds
How are peptide bonds formed?
A condensation reaction
What happens to the amine group of one amino acid and the carboxyl group of another?
A peptide bond is formed between the amine group of one amino acid and the carboxyl group of another through a condensation reaction
Two amino acids join together in a chain to form…
A dipeptide
Many amino acids join together in a chain to form…
A polypeptide
What does a protein consist of?
One or more polypeptides
How can proteins be hydrolysed?
Heating with acid
Use of the enzyme protease at its optimum temperature
