topic 2.4: Proteins
Essential Idea:
- Proteins have a very wide range of functions in living organisms.
Protein structure.
2.4U1: Amino acids are linked together by condensation to form polypeptides.
2.4U2: There are 20 different amino acids in polypeptides synthesized on ribosomes.
2.4U3: Amino acids can be linked together in any sequence giving a huge range of possible polypeptides.
2.4U4: The amino acid structure is coded for by genes.
2.4U5: A protein may consist of a single polypeptide or more than one polypeptide linked together.
2.4U6: The amino acid sequence determines the three-dimensional conformation of a protein.
2.4 NOS: Looking for patterns, trends and discrepancies--most but not all organisms assemble proteins from the same amino acids.

Protein function.
2.4U7: Living organisms synthesize many different proteins with a wide range of functions.
2.4U8: Every individual has a unique proteome.
2.4A1: Rubisco, insulin, immunoglobulins, rhodopsin, collagen and spider silk as examples of the range of protein functions.
2.4A2: Denaturation of proteins by heat or by deviation of pH from optimum
2.4Skill1: Drawing molecular diagrams to show the formation of a peptide bond.
