Amino Acids, Essential and Nonessential

Amino Acids, Essential and Nonessential

aminoacidsAmino acids are the building blocks of life. They are tiny molecules that contain nitrogen. There are twenty-two naturally occurring amino acids, twenty of these are found in human cells. These twenty are the building blocks of the human body. They hook together to form enzymes, hormones, immune molecules and neurotransmitters. The human body has the ability to make some of these, but others must come from food.

Non-essential

From the time humans are infants, their bodies produce non-essentials. The non-essential amino compounds are manufactured from similar compounds or amino acids that are already in the body. Among the natural occurring non-essential amino acids are tyrosine, serine, proline, glycine, glutamine, glutamic acid, cysteine, adpartic acid, asparagines and alanine. One non-essential is only produced in adults is called arginine. Infants and children cannot make enough to meet their own needs, they get them from their diet.

Essential

There are nine aminos that adults need, but cannot produce naturally. The only way to get them is through diet. A body cannot be healthy if the essential are present. These are not needed on a daily basis, the body does store and reuse them to some extent, but they do need replenished. The essential amino acids include, valine, tryptophan, threonine, phenylalanine, methoinine, lysine, leucine, isoleucine and histidine. Arginine is necessary in babies and children, as their bodies do not produce it naturally. Proper nutrition insures that essential vitamins and nutrients occur naturally. Supplements will add the correct amount for the body to function and develop properly.

Conditionally Essential

To produce the nonessentials there needs to be vital nutrients and other precursors. If these are not present, they will render a nonessential conditionally essential. Glycine is a nonessential; it is produced with the help of vitamin B6 and serine hydroxymthyltransferase. If the body does not have enough vitamin B6, it cannot change serine to glycine. Vitamin B6 can only be obtained from taking a vitamin.

Considerations and Recommendations

The body needs amino acids to function and grow. The absence of any of these will result in the body attempting to find them elsewhere by breaking down proteins. If diet does not give the body the essential and nonessential amino acids, they must be ingested from other sources. Adding the appropriate supplements will prevent these from being absent. Taking a mixture of all will prevent amino acids from being deficient. Taking individual supplements may cause an imbalance and competition among the amino acids that are present. The right balance will provide the body with the proper nutrients to build muscle and remain healthy.
