Essential Amino Acids
Essential amino acids are a group of nine amino acids absolutely essential to human diets. The amino acids essential to human diet are not necessarily essential to other species, since not every species shares the same metabolic process. Here is a list of the essential amino acids for human: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Arginine is also essential, but for young children and not for adults.
Histidine
Histidine plays a significant role in repairing the body tissues, development of body tissues, myelin sheath maintenance, production of white and red blood cells. The presence of histidine becomes especially evident when someone catches any sort of allergic reaction. Moreover, histidine also offers protection against radioactive damages.
Isoleucine
Isoleucine offers protection against muscle cramp during post-exercise phase. In addition, isoleucine plays a significant role in hemoglobin production, blood sugar level management, blood coagulation. Inadequacy in isoleucine level may lead to depression, lethargy, irritation, confusion and so on.
Leucine
Leucine is responsible for blood sugar management, muscle tissue development, hormone production, and energy regulation. Inadequacy in leucine level may lead to headache, dizziness, fatigue, irritation, and so on.
Lysine
Lysine is very critical for children, especially for infants and toddlers, since it is highly responsible for bone development. It significantly influences calcium absorption process and nitrogen maintenance in the body. Inadequacy in lysine level may lead to hair loss, weight loss, anemia, complications in reproductive system and retarded growth.
Methionine
Methionine helps in fatty acid assimilation and puts off fatty elements to be stored over the artery walls. In addition, it aids in liver detoxification process, promotes energy production, develops muscles. It also plays a significant role as an antioxidant.
Phenylalanine
Phenylalanine influences nervous system significantly, hence it has a major impact on the mood regulation, memory system, learning process. Inadequacy in phenylalanine level may result in depression, Parkinson’s disease, fatigue, skin irruption, chronic pain, and slow growth.
Threonine
Threonine is responsible for protein management in the body system. It also influences collagen formation, skin elasticity maintenance, liver function, immune system balance, thymus growth and antibody production.
Tryptophan
Tryptophan aids in vitamin B as well as serotonin production in the body. Hence it has a deep impact in maintaining the balance in the nervous system and braining functioning. Children’s hyperactivity is somewhat influenced in the presence or absence of tryptophan.
Valine
Valine is exclusively responsible for tissue growth and muscular metabolism. It has a great stimulant impact. Inadequacy in valine level may lead to alcoholism, drug addiction and other form of obsessive-compulsive behavior, and maple syrup urine disorder.
