What is the difference between biochemistry and chemistry?

Biochemistry studies the chemistry of life -- how life works at the molecular level, what kinds of chemical reactions occur in cells, and how these reactions give an organism its observed characteristics. The field overlaps in many areas with disciplines like molecular biology and genetics. A great deal of chemistry knowledge is involved -- especially knowledge of organic chemistry since most of the important reactions that take place in organisms involve carbon compounds. Inorganic chemistry is involved as well, however, since many enzymes have metal-ion cofactors.

Chemistry comprises several distinct subdisciplines, namely, physical, inorganic and organic chemistry. In some ways, it's a broader field than chemistry, since it's concerned with the structure and behaviour of matter and the types of reactions compounds can undergo. The dividing line between biochemistry and chemistry is a little fuzzy, but in general, chemists are interested in designing useful new materials, finding more efficient ways to synthesize existing materials, or understanding why substances have the property that they do, while biochemists use chemistry to understand why and how certain processes take place in living organisms.

Chemistry is one of the basic sciences that studies the organic and inorganic substances and interactions of atoms and molecules.

Biochemistry is and interdisciplinary science that has composed of chemistry and biology. It studies all the reactions inside and outside of cells. In other words, biochemistry is the chemistry of life.

 biochemistry  is the part of chemistry that studies biochemicals such as enzymes, hormones.. and all what marks and builds the living systems   

we can say that it combines the wonders of biology with the rules of chemistry
