Some of these enzymes pose problems because they have a very wide specificity, and it is not easy to decide if two preparations described by different authors are the same, or if they should be listed under different entries. While the systematic name always includes 'hydrolase', the common name is, in most cases, formed by the name of the substrate with the suffix -ase.
It is understood that the name of the substrate with this suffix, and no other indicator, means a hydrolytic enzyme. It should be noted that peptidases have recommended names rather than common names. They differ from other enzymes in that two or more substrates are involved in one reaction direction, but there is one compound fewer in the other direction.
When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring. The systematic name is formed according to 'substrate group-lyase'. In common names, expressions like decarboxylase, aldolase, etc. In cases where the reverse reaction is the more important, or the only one to be demonstrated, 'synthase' may be used in the name. Ligases: Ligases are enzymes that catalyse the joining of two molecules with concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.

They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism. Some enzymes help break large molecules into smaller pieces that are more easily absorbed by the body.
Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction.
