How to analyze the KEGG COMPOUND database, I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

The kegg compound database stores a variety of small molecules, biological macromolecules and other types of chemicals that play a role in life activities, identified by C number, such as C00047, which stands for L-lysine. In addition to the name and other information, the chemical structure and other related information of the substance are also stored.

For the classification of all compound, please see Brite database.

Including organic acids, lipids, carbohydrates, nucleic acids, peptide chains, vitamins and cofactors, steroids, hormones and transmitters, antibiotics

Take a look at the details of each record, taking formic acid C000 as an example

The above information can be divided into two main categories:

1. Basic information

EntryC Number, the unique identifier in the database Name name Formula chemical formula Extract Mass mass Mol weight molecular weight structure structure

two。 Links to other databases

Reaction the ReactionPathway involved in the molecule, the pathway in which the molecule is involved, the pathway in which the molecule is involved, the moduleEnzyme in which the molecule is involved, the link to the third party database of the enzyme DB related to the molecule.

The Reaction database stores reactions between various compound, so there will be links to Reaction, such as R00134

Pathway database integrates the information of ko, module, reaction, compound and other databases, so it will also give the path in which compound participates. In the path, the corresponding compound will be highlighted, as shown in the following figure.

Module is a collection of ko, but ko is only a set of genes. It is the products of these genes that really participate in life activities. When the products play a role, they also need the participation of compound, all of which will give compound-related module.

The Enzyme database stores relevant information about various enzymes. Enzymes act as catalysts to regulate the occurrence and progress of some biological processes, and compound will certainly be involved in this process. For example, in the reaction catalyzed by 1.1.1.306, the donor provides formic acid to carry out the reaction, so the corresponding Enzyme number of compound will be given.

The compound database stores the information of various molecules involved in life activities. The records in the database are uniquely identified by C Number, and each molecule has its corresponding chemical formula, structural formula, molecular weight and other basic information.

Compound is associated with reaction, module, pathway, enzeme and other databases.

After reading the above, have you mastered the method of how to analyze KEGG COMPOUND database? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
