Rapid Learning for NEET PG : Biochemistry Mnemonics
![](http://courses.egurukulapp.com/blogs/wp-content/uploads/2021/10/pexels-bich-tran-760710-1024x681.jpg)
Medical students face a major challenge when it comes to recalling medical terms, and applying them to answers, properly. In addition to a good NEET PG exam preparation strategy, one needs to have a good memory to remember important information, which will ultimately help in acing this competitive medical PG exam. In light of this, we’ve put together some mnemonics that many successful candidates use as a strategy to recall information.
When used correctly, mnemonics can be effective learning aids, such as for helping you remember chemical names in biochemistry. Memory is improved by leveraging various naturally occurring processes such as visual imagery, organization, and elaborative encoding. It appears that acronyms and acrostics are among the most widely used mnemonics. Following that are the keyword method and usages of stories, songs, and imagery. Studies have found that students who learned musical jingles to remember statistical facts outperformed students who reread the facts on a chapter test. By learning basic facts with mnemonics, you will have more time for higher-level learning.
The essential amino acids are also referred to as indispensable amino acids. Amino acids in biochemistry mnemonics are the acids that cannot be synthesized through humans and vertebrates from the metabolic intermediates. The human body doesn’t have metabolic pathways, so amino acids supply these components through an exogenous diet. The amino acids are classified either as essential or non-essential in context with nutrition and mnemonics.
Advantages of Mnemonics
Students often face difficulty in learning the disabilities, assessing, retaining, and recalling the mnemonics information because it is complex. However, one of the easiest ways for students to deal with the challenges of learning and retaining information is through mnemonic strategies.
- Mnemonic strategies are memory-enhancing strategies for students.
- The mnemonic strategies are easy to understand, assess and recall because it provides visual or auditory clues for students to help make connections between the elements that further help in the examination paper.
- Mnemonic strategies are highly effective. It allows students to understand the new information more easily and faster compared to traditional methods of learning biochemistry modules, compounds, and elements.
How to apply mnemonics in biochemistry concepts?
Classification of Amino acids based on the structure:
Non-polar- Aromatic – Phenylalanine and Tryptophan (mnemonic- Phenil Trypathy )
Non-polar- Alkyl- Leucine, Valine, Isoleucine, Proline, Glycine, Alanine, Methionine
(mnemonic- Lost VIP GAMe )
Amino acid names can be learned as Phenil Trypathy Lost VIP GAMe.
A list of mnemonics is provided for reference.

Van den Bergh’s reaction is also known as the Jaundice test. In the test, Unconjugated bilirubin = Indirect reacting bilirubin.
Enzymes
Enzymes are competitive inhibitors. The competition in enzymes is difficult because they have to travel from one place to another with the constant or same velocity altogether. The competitive inhibitors have the same velocity but the kilometers increase one after the other.
Adrenaline mechanism
The ABC of Adrenaline is explained with the following equation:
Adrenaline–> activates Beta receptors–> increases Cyclic AMP
It shows that adrenaline activates the beta receptors in our body that increase the cyclic AMB and it causes adrenaline.
