All proteins are polymers of which kind of amino acid?

  1. Gamma amino acids
  2. Delta amino acids
  3. Sigma amino acids
  4. Alpha amino acids
Show answer and solution

Correct answer: D. Alpha amino acids

1. Amino acids differ in where the amino group sits. 2. Only one class comes out of protein hydrolysis. 3. Proteins are polymers of alpha amino acids. _Source: syllabus Chemistry Part 2, Unit 10 'Biomolecules'_

The five membered ring form of fructose is called the:

  1. Formazan form
  2. Furanose form
  3. Fumarate form
  4. Ferrocene form
Show answer and solution

Correct answer: B. Furanose form

1. The hydroxyl at carbon five closes the ring. 2. Four carbons and one oxygen make up the ring. 3. It is named after furan, so furanose. _Source: syllabus Chemistry Part 2, Unit 10 'Biomolecules'_
