Structural material: proteins form integral parts of most body tissues, provide strength and shape to skin, tendons, membranes, muscles, organs and bones. Hormones: proteins regulate body processes (some but not all hormone are proteins) Acid-base balance: proteins help maintain acid-base balance of body fluids by acting as buffers.

Other: protein fibrin creates blood clots, protein collagen forms scars [scar formation, protein opsin participates in vision. Consists of: amino group, acid group, hydrogen atom. Essential amino acids must be consumed in the diet: tryptophan: relaxing properties, creates serotonin; ex: turkey, know the essential aa for the test!!
