E8D

E8D is an alphanumeric designation used in various domains to label different items, such as a protein variant, a catalog part, or a software/build identifier. There is no single universal meaning for the code; its interpretation depends on the context and the issuing organization.

In biology and genetics, E8D is a shorthand notation used to describe a point mutation in a protein sequence. It indicates that the amino acid glutamic acid (E) at a given position—commonly position 8—has been substituted with aspartic acid (D). This kind of notation appears in scientific literature and sequence databases to describe protein variants, and the exact position and implications depend on the specific protein being studied.

In manufacturing and engineering, E8D often serves as a model number or catalog code assigned by a company to designate a particular product, component, or kit. The same code can refer to different items across vendors, so the precise specifications, dimensions, and用途 require consulting the respective datasheet or catalog.

In software and data management, E8D may surface as a build identifier, release code, or environment tag within a project. It is not a standardized naming convention, and its meaning is defined by the development workflow or versioning scheme used by the team or organization.

In transportation and infrastructure contexts, E8D can appear as an internal designation for equipment configurations, route classes, or project components. As with other uses, the specific meaning is dependent on the issuing body and documentation.
