A polypeptide is a polymer formed from many amino acids joined by peptide bonds through condensation polymerisation. The Amino Acids and Polypeptide Formation notes cover this in full.
Ethanol can be written as CH₃CH₂OH or C₂H₅OH, and its molecular formula is C₂H₆O. The Introduction to Alcohols and Their Structure notes cover this in full.
DNA (deoxyribonucleic acid) is a large molecule essential for life that encodes genetic instructions for the development and functioning of living organisms and viruses. The DNA Structure and Function notes cover this in full.
The formula of glucose is C₆H₁₂O₆. The Naturally Occurring Polymers and Their Monomers notes cover this in full.
Crude oil formed millions of years ago from dead sea creatures and plants. The Understanding alkanes as saturated hydrocarbons notes cover this in full.
A composite material combines two materials with different properties: a matrix that surrounds and binds together fibres or fragments of a reinforcement. The Material Properties and Composites notes cover this in full.
To test for sulfate ions, add a few drops of dilute hydrochloric acid to the solution, then add barium chloride solution. The Testing for Sulfate Ions notes cover this in full.
The test for hydrogen is to hold a burning splint at the mouth of the test tube: if hydrogen is present, it burns rapidly with a pop sound. The Testing for hydrogen gas notes cover this in full.
