HEY ALL ?..

Here are a few important questions from Biomolecules, Chemistry in everyday life and polymers?..these are the chapters which the students leave for last minute and then finally go without reading the chapters fully?..

I assure u that if u read these then surely u will score well or rather full in these chapters?..

I have the answers too?.so if u don?t know the answer to any question you can nudge me!!

I have divided the post into two- one with questions on biomolecules and second will have questions on chemistry in everyday life and polymers.

· Reducing and non reducing sugars

· Alpha D glucose and Beta D glucose

· Globular and fibrous protein

· Alpha helix and beta pleated structure of proteins
