Another difference is that proteins are combinations of 24 different amino acids.
Classifications of Protein
• Complete - foods which contain all the essential amino acids in significant amounts and in the proportions to maintain life and support growth when used as the sole source of protein food.
• Partially incomplete - those which contain amounts of the essential amino acids to support lie but not maintain growth.
• Incomplete - those which will not support growth.
Function of Protein
• Growth and maintenance
• Enzymes
• Hormones
• Antibodies
• Fluid and electrolyte balance
• Acid/base balance
• Energy
Digestion of Protein
• Proteins must be broken down into amino acids to be absorbed.
• Digestion of amino acids is slow (12 hours to get benefit of protein mail with proper food combining).
• Mechanisms of protein digestion are the
- mouth - small bites
- stomach - hydrochloric acid (HCl - see previous post) converts the inactive enzyme pepsinogen into pepsin, which breaks down protein into polypeptides)
- small intestine - pancreatic enzymes and intestinal secretions break down polypeptides into amino acids for assimilation by the body. Absorbtion takes place here.
Sources of Protein
1. Animal sources - meat, fish, eggs, cheese
2. Plant sources - beans, lentils, nuts
Signs of possible Protein deficiency
• excess moisture (edema, eyes, mucous)
• depression
• wired
• unrestful sleep
• feels hungry/eats without listening to body
• difficult to lose weight
• TMJ
• Immune system problems
• Hormone imbalances
