Biochemistry is an important subject as it is high scoring subject and direct questions are asked from this subject every year. Due to time constraints, preparing this subject can be demanding and burdensome as it needs lots of memorization and in-depth understanding of concepts.

Biochemistry, being a subject related to chemical and physico-chemical processes, can be easily correlated with physiology and medicine as well. Certain topics which you covered in physiology & medicine will be revised in this subject.

Important tips to prepare and topics imperative in this subject are compiled in this blog to assist you in your preparations.

Tips to Prepare:

  • Prepare notes and good mnemonics for memorizing various cycles and lists.
  • As time is a limiting factor, focus on topics that are most important and highly expected in the exams.
  • Repetition is the mother of all learning, thus review your notes the same day and everything again on weekends.
  • Self-evaluate your preparation by taking mock tests.


List of Topics to be prepared in biochemistry for MDS entrance exams:

  • Fatty acids and its synthesis
  • Cholesterol including description of good & bad cholesterol
  • Niemann Pick Disease



Good command over basics is necessary as it helps in easy understanding and memorizing. So, following topics should not be missed while covering general biochemistry.

Topics include:

  • Cell organelles
  • Karyotyping/Giemsa Stain-G Banding



It is another important topic to be prepared meticulously for MDS entrance exams. Know about various enzymes, along with their mechanism and functions.

Important sub-topics to be prepared are:

  • Coenzymes
  • Transferase
  • Kinase
