2.4 Proteins
- Nature of Science
- Most organisms
assemble proteins
from the same 20
different amino acids
- Genes
- Genetic code
is universal
- 20 different
amino acids
- Condensation
- Polypeptides
formation
- Huge range of
possible polypeptides
- Protein is a single or more
than one polypeptide
- The amino acid sequence
determines the 3D
conformation of a protein
- Every individual has
a unique proteome
- Functions
- Rubisco
- Insulin
- Immunoglobin
- Rhodopsin
- Collagen
- Spider silk
- Denaturation
- pH
- Heat
- Practical: egg
white or albumin
- Aim7
- ICT for molecular
visualisation
- Primary structure
- Secondary Structure
- Tertiary structure
- Quaternary structure
- Hemoglobin (Hb) made
of 4 polypeptides
- Radical (R) from
amino acids
- Alpha helix
- Beta pleated sheet
- Peptide bonds
between amino acids
