Why do we need ChEBI?
Molecular biologists and biochemists encounter small molecules on a regular basis – after all, small molecules participate in all the processes of life: for example, as neurotransmitters, as intermediates in cell metabolism, in biological pathways and in drug design. However, although the field of 'small molecules' is important, it is not the prime interest of most biologists. As a consequence, small molecules frequently appear in databases simply as free text, which leads to problems. We will discuss some examples of these in the next section.

Where ChEBI records have been merged, the ChEBI IDs of the merged records are never lost. One is retained as the primary ID whilst the others are listed as secondary IDs. Searching for either primary or secondary IDs will take you to the same record.
