  • proteins
    • structures such as hair and nails (feathers in birds) are made from proteins
    • cell structures (proteins are components of the membranes which form boundaries of the cells)
    • muscle fibres (the muscles contract or relax when protein molecules they contain slide over one another)
    • enzymes are proteins; highly specific catalysts; control the rates of the reactions in the body)
    • hormones regulate many processes in the body (not all are proteins)
    • binding proteins (substances are stored or transported around the body by proteins
