    Protein Nutrition: Understanding Structure, Digestibility, and Bioavailability for Optimal Health.
    (MDPI (Basel, Switzerland), 2024-06-05) Ajomiwe N; Boland M; Phongthai S; Bagiyal M; Singh J; Kaur L; Wei Z
    This review discusses different protein sources and their role in human nutrition, focusing on their structure, digestibility, and bioavailability. Plant-based proteins, such as those found in legumes, nuts, and seeds, may contain anti-nutritional factors that impact their bioavailability apart from structural and compositional differences from animal proteins. Animal proteins are generally highly digestible and nutritionally superior to plant proteins, with higher amino acid bioavailability. Alternative protein sources are also processed in different ways, which can alter their structure and nutritional value, which is also discussed.

    Relative orientation of collagen molecules within a fibril: A homology model for homo sapiens type I collagen.
    (Taylor & Francis, 30/01/2018) Collier TA; Nash A; Birch HL; de Leeuw NH
    Type I collagen is an essential extracellular protein that plays an important structural role in tissues that require high tensile strength. However, owing to the molecule’s size, to date no experimental structural data are available for the Homo sapiens species. Therefore, there is a real need to develop a reliable homology model and a method to study the packing of the collagen molecules within the fibril. Through the use of the homology model and implementation of a novel simulation technique, we have ascertained the orientations of the collagen molecules within a fibril, which is currently below the resolution limit of experimental techniques. The longitudinal orientation of collagen molecules within a fibril has a significant effect on the mechanical and biological properties of the fibril, owing to the different amino acid side-chains available at the interface between the molecules.
