The objectives of this study were: (1) to determine the protein
chemical profiles, protein degradation and intestinal
digestion of the co-products from cereal grains; (2) to reveal the
protein molecular structures (in terms of amide I and amide II
intensity and their ratio; ɑ-helix and b-sheet intensity and their
ratio); (3) to investigate the relationship between protein molecular
structures and chemical profiles, protein subfractions
partitioned by Cornell Net Carbohydrate and Protein System
(CNCPS), protein degradation and digestion; (4) to determine
the most important structural features for the co-products
from cereal grains. In this study, the hypothesis is that the
protein molecular structure was associated with protein utilization
and availability. Different ethanol and beer-making coproducts
have different protein molecular structures and
different protein degradation and digestion behaviors
