1. Intro & The History Of Protein.
The word 'protein' is defined as any of a group of complex high-molecular-weight organic compounds, consisting essentially of combinations of amino acids in peptide linkages, that contain carbon, hydrogen, oxygen, nitrogen, and usually, sulfur.
Proteins are one of the classes of bio-macromolecules (like polysaccharides, lipids, and nucleic acids), that make up the primary constituents of living things.
The History Of Protein:
Proteins were discovered by Jöns Jakob Berzelius in 1838 and are among the most actively-studied molecules in biochemistry. The word "Protein" is derived from a Greek word "protas" meaning "of primary importance," because of the fundamental role of proteins in sustaining life.
- Muscle and tissue growth (especially important for children, teens, and pregnant women)
- Muscle and tissue repair
- Regulating the pH, or acid-base balance, in the blood
- Preserving lean muscle mass; especially when on a low carbohydrate diet
- Controlling many of the important processes in the body related to metabolism
- Providing energy when carbohydrate is not available
- Making essential hormones
- Making and enzymes or subunits of enzymes, catalyzing chemical reactions
- Immune function via protein antibodies
- The storage and transport of various ligands
- Maintain body fluid balance through blood proteins, preventing a condition known as edema (buildup of excess fluid outside body cells)
Protein has many important roles in the body; they are part of every cell: muscles, connective tissue, blood-clotting factors, enzymes, immune bodies, hormones, and bones.
Protein Is Needed For:
Protein Food Sources:
- Meat (e.g., beef, pork, lamb and veal)
- Meat substitutes (soy)
Protein is found in common foods such as:
It can also be found, although in much smaller quantities, in some starchy foods and vegetables. Eating a diet rich in these foods is a good way to get protein.
However some of these items can also be high in cholesterol, fat and calories, so picking the right cuts (for poultry, fish and meets) and the right dairy as well as considering how they are prepared to maintaining a lean physique and to good overall health.
