Aliphatic index

aliphatic_index · Sequence-derived

Relative volume of aliphatic side chains: Ala% + 2.9·Val% + 3.9·(Ile%+Leu%). Higher values associate with thermostability. Validated vs peptides.py.

Computed value — a deterministic descriptor validated against independent reference implementations; not an experimental measurement, and it carries no evidence support-class. Computed from the standard parent-residue sequence (a protein-origin metric, defined at any length). Not available for modified or non-standard sequences.
