Respuesta :
Ten out of the twenty amino acids found in living organisms are termed essential because these amino acids cannot be made naturally by the body system. They must be consumed in diets.
An amino acid is determined to be essential if:
- It is needed for important metabolic functions in the body
- It cannot be synthesized by the boy at all or at a rate that is needed by the body.
Thus, such amino acids must be consumed in order to meet the demand of the body. This is unlike non-essential amino acids that are synthesized freely by the body system.
The amino acids that have been deemed to be essential include the likes of leucine, isoleucine, histidine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
