|Analytical biochemistry is the study of analysing biochemical components found in a cell or other biological sample. Analytical biochemistry uses a broad range of techniques for separation, identification, quantification and functional characterization of biological molecules. It helps us to understand the insights of complex biological process in the cell. 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.
