  6. Proteins • Some fold into structure with small holes • -Are enzymes that help “biochemical” reactions -Are helpful to metabolism -Are important in cell signalling - immune responses -cell adhesion -cell cycle.

  7. Protein (cont.) • Are parts of organisms and process within cells • Has its own amino acid • people who eat vegetarian can still get protein-rich foods. • Examples • -meat ,grains, dairy ,nuts.

  8. Fibre • Soluble fibre absorbs water • gelatinous, is cloaked by bacteria in the digestive tract. • Insoluble fibre is not fermented. • major dietary insoluble fibre source. • lignin may alter metabolism of soluble fibres.
