|Biochemistry also called as biological chemistry which is the study of chemical processes relating to living organisms. Much of biochemistry deals with the functions, structures and interactions of biological macromolecules which include nucleic acids, proteins, lipids and carbohydrates, which will provide structure of cells and help to perform many of the functions which are associated with life. High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
