The semi-synchronous orbit is a near-circular orbit (low eccentricity) 26,560 kilometers from the center of the Earth (about 20,200 kilometers above the surface). A satellite at this height takes 12 hours to complete an orbit.his special, high Earth orbit is called geosynchronous. A satellite in a circular geosynchronous orbit directly over the equator (eccentricity and inclination at zero) will have a geostationary orbit that does not move at all relative to the ground. It is always directly over the same place on the Earthâs surface.
The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.ydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
In the food industry hydrochloric acid is used to regulate the pH of solutions. High-quality hydrochloric acid is used to control the pH of water streams. It is also used to create food additives such as aspartame, fructose, citric acid, lysine, hydrolyzed vegetable protein. It is also used in the creation of gelatin.Hydrochloric acid is used in the process of removing ions such as sodium and chloride from water. It is used to demineralize water for use in industry, food and pharmaceuticals. It is also used to neutralizing waste water and sanitizing swimming pools.umerous other organic compounds are made from Hydrochloric acid for use in pharmaceuticals. Hydrochloric acid is used to create inorganic compounds such as iron chloride and polyaluminium chloride (PAC) . These are used as water treatment chemicals and coagulation agents for paper production.
