UNIT 1

INTRODUCTION TO BIOCHEMISTRY

ROLE OF BIOCHEMISTRY

• TO STUDY RELATION SHIPS OF

structures ,functions and interactions of biological macromolecules like proteins ,nucleic acid LIPIDS which provide structures of cell and perform many functions.

BIOMOLECULES

• ORGANIC COMPOUNDS THAT INCLUDES

• CARBOHYDRATE

• LIPIDS

• NUCLEIC ACIDS

• ENZYMES

• IMPORTANT FOR SURVIVAL OF LIVING CELLS

CARBS

GLUCOSE

MONOSACCHARIDES

IMPORTANCE of AMINO ACIDS

BIOLOGICAL IMPORTANCE OF AMINO

SUGARS

• (^) AMINO SUGARS AND WHY THEY ARE IMPORTANT
• (^) Amino sugars are constituents of structures found in all tissues, mostly on the surface of cells and in the spaces between them, forming the substance that binds cells together, membranes that envelope them and protective layers that cover them.
• (^) Unlike most sugars that are obtained in the diet and are oxidized for energy, amino sugars are formed in the body from glucose and are committed entirely to the formation of structural components.

• (^) “glue” that holds tissues together is a meshwork of fibers of the protein collagen together with giant molecular complexes of proteoglycans, where approximately half of the constituent molecules are amino sugars
