Differences among amino acids, essential amino acids and nonessential amino acids

Amino acids are the material basis of human life metabolism and the basic unit of protein The production, existence and extinction of life are all related to protein If there is a lack of protein in the human body, the constitution of the light person will decline, the development will be slow, the resistance will be weakened, the anemia will be weak, the heavy person will form edema, even life-threatening 　　   Eight of the 20 amino acids that make up human protein are "essential amino acids" which can not be synthesized by human body or can not meet the needs of human body If the human body lacks any kind of essential amino acids, it can lead to physiological dysfunction, affect the normal metabolism of the body, and finally lead to disease "Nonessential amino acids" cannot be misunderstood as nonessential, but they can be transformed from other amino acids in the body, not necessarily from food supply If the human body lacks some nonessential amino acids, it will produce metabolic disorders Only when the ratio of "essential" and "nonessential" amino acids is appropriate can the utilization rate of amino acids be increased When the human body lacks amino acids, there will be problems: 1 Influence on brain tissue of central nervous system: it is easy to cause Alzheimer's disease and Parkinson's disease; 2 Effect on cardiovascular system: the elasticity of blood vessel declines, leading to atherosclerosis; 3 Effect on liver: fatty liver is easy to form; 4 Influence on kidney: lead to low renal function; 5 Effect on gastrointestinal system: forming digestive and absorption dysfunction; 6 The influence on the motor system: the muscle fiber decays and shrinks, the energy supply drops, the limbs are easy to be weak and weak; 7 The effect on the immune mechanism of human body: once the protein is insufficient, the resistance of the elderly will decline, and various diseases will easily occur; 8 When the supply of amino acids is insufficient, that is to say, the raw materials for the synthesis of antioxidant enzymes and antioxidants are insufficient The accumulation of free radicals and acid substances will accelerate the aging of human body If there are too many free radicals, the small is fatigue, the large is aging In a word, amino acids are the raw materials for the synthesis of human protein, hormone, enzyme and antibody With the improvement of people's health care and nutrition awareness, the need for amino acid nutrition must be gradually increased.
