Definition

Meaning and Definition

A univalent radical derived from alanine, an amino acid.

The term specifically refers to the acyl radical (−NH−CH(CH3)−CO−) or the residue in a peptide chain derived from alanine. It's a fundamental building block in biochemistry and peptide/protein chemistry.

Common Mistakes When Using “alanyl”

  • Using it as a general term for alanine.
  • Misspelling as 'alanil' or 'alanyle'.
  • Attempting to use it in non-scientific contexts.

FAQ

Frequently Asked Questions

No. Alanine is the full amino acid. Alanyl refers specifically to the radical or residue form of alanine when it is part of a larger molecule like a peptide or protein.

No. It is a highly technical term with no application in general English. Its use would be confusing outside of scientific contexts.

It is often abbreviated as 'Ala-' or simply 'A' in peptide sequences (e.g., Ala-Gly-Ser). In structural formulas, it is depicted as −NH−CH(CH3)−CO−.

Yes, many amino acids have corresponding radical forms: glycyl (from glycine), leucyl (from leucine), phenylalanyl (from phenylalanine), etc. They all follow the same '-yl' suffix pattern.

A univalent radical derived from alanine, an amino acid.

Alanyl is usually technical/scientific in register.

Alanyl: in British English it is pronounced /ˈælənaɪl/, and in American English it is pronounced /ˈæləˌnɪl/ or /əˈlænəl/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Think 'ALA-nine' (the amino acid) + '-NYL' (like the ending of 'vinyl' or 'phenyl'), signalling it's a chemical group derived from alanine.

Conceptual Metaphor

A BUILDING BLOCK or MODULE within the larger structure of a protein.
