Abstract:

Peanut germplasm resources are very rich and diverse in China, and subunit composition, molecular structures
and functional properties are different in different peanut varieties. In this paper, the subunit composition of major peanut
protein components such as arahin, conarachin and albumin is overviewed. Herein, we provide a systematic review of the
recent progress made in the studies of the molecular structures of arahin and conarachin and the functional properties of each
subunit at the subunit level. In addition, some problems encountered in the research on peanut proteins are summarized and
the future research direction is proposed, aiming to provide a reference for researchers in this field.

Key words: peanut protein, subunit, structure, functional property
