Storage Proteins
2.2. Oxygen binding Today scientists try to explore the chemistry basis behind the biological processes. As a result of this, new areas have evolved such as bioinorganic chemistry and bioorganic chemistry. In this section we will talk about an important concept in bioinorganic chemistry called “Metallobiomolecules”.

1.0 Introduction to Metallobiomolecules
As we already know, biomolecules are molecules appear in biological systems to perform a specific function, like carbohydrates, proteins, lipids and nucleic acids. Metallobiomolecules are molecules associated with metal ions which play a major role in regulating biological processes, like biomolecules do. Characteristic feature of metallobiomolecule is as the name implies association of metal ion with molecular part. Classification of metallobiomolecules can be done based on several criteria. Let us consider the classification component.
2.0 Classification of Metallobiomolecules
As previously mentioned, association of metal ion is the characteristic feature of metallobiomolecules. That mean metal ion part is common for all metallobiomolecules. Depending on the nature of the other molecular part, metallobiomolecules can be divided into three categories.

1. Transport and Storage Proteins: Molecular part is belongs to the group of Proteins, but they are not enzyme and perform the transport and storage function. Myoglobin (Fe), Hemoglobin (Fe), Hemocyanin (Cu), Cytochromes (Fe) and Blue copper (Cu) Proteins are some examples. 2. Enzymes: Molecular part is belongs to the group of Proteins, and also they are enzymes. They perform the catalytic function. According to the type of
