Biomolecules

Ever wanted to know the story of creation from a non biological point of view? Look no further! Biomolecules is the very story that you were looking for. After all, it is DNA that gives us the traits that make us… it is Proteins, Vitamins and Sugars that give us the fuel to feed the fire of life. Let’s have a look at what this unit entails.

Tips & Tricks

• The chapter kicks off with an introduction to a basic study of amino acids, their Isoelectric points, and the different types of amino acids. This is an essential part of this chapter and purely logical. It’s important to practice a lot of questions on the isoelectronic points of amino acids.
• Certain amino acids are essential to know structurally. Say for example, glycine, alanine and valine. A few more are important too. Note them and revise frequently to permanently affix them in your minds.
• Sugars and their classification is the next important part. Much more important, however, are the structures of glucose/fructose and other D-aldoses. There are 15 in total. Here is a table to help you memorize.
• 
• Haworth and Fisher projections of glucose and fructose are of prime importance, as are the concepts of Mutarotation and Reducing Sugars. Read them from LG Wade or your coaching material.

• Protein structures are another important concept and you should be very clear with what each terms means – Primary structure, secondary structure, tertiary structure and quaternary structure.

• Catalysts and enzymes are important, though not as much as the concepts mentioned above. You should just know what mechanism is followed by enzymes and catalysts and how they affect reactions (Reduce activation energy or change mechanism, but do not alter Enthalpy change of the reaction. This ensures that only kinetics is affected, and not the thermodynamics/equilibrium of the reactions).

That’s all for Biomolecules. Note these concepts well, practice a lot of questions (especially from MS Chouhan : Advanced Problems in JEE) and revise frequently…

Keep practicing and thinking. It takes a lot of time and perseverance to master organic chemistry. Don’t think that you will be able to do it in one go. You need to keep doing it again and again

 

Periodic properties

Hi,today we are going to discuss about periodic properties trends like atomic radius, electronegativity,electron affinity, hydration energies, ionisation energies,some more terms..

We know all those terms but major problem in inorganic chemistry How to remember that part ? Also at the exam time we suffered how to revision that part !!!

We are supposed to you all terms known.so ready to learn easy way to remember all trend

so, in this above IMG. Arrow are showing all those properties. At last I want to share one thing :-

• .you know what ?Much more important than these chapters is how well you prepare, how much you have solved problems in inorganic chemistry.
• Keep practicing and thinking. It takes a lot of time and perseverance to master inorganic chemistry. Don’t think that you will be able to do it in one go. You need to keep doing it again and again.This method also very useful in organic chemistry while you’re prepare for that. Soon we will come with next discussion on ELECTROPHILLIC AROMATIC SUBSTITUTIONS (EAS)-Organic chemistry.
• So use this & prepare well…😀
