Final answer:
Histidine is considered essential for adolescents and non-essential for adults. Histidine is an essential amino acid that plays a crucial role in the synthesis of histamines, hemoglobin, and enzymes. It is found in various protein-rich foods such as meat, poultry, fish, dairy products, and legumes.
Step-by-step explanation:
The amino acid that is considered essential for adolescents and non-essential for adults is Histidine (H).
During adolescence, the body requires histidine for growth, development, and tissue repair. However, in adults, histidine can be synthesized in sufficient amounts by the body and is therefore considered non-essential.
Histidine is an essential amino acid that plays a crucial role in the synthesis of histamines, hemoglobin, and enzymes. It is found in various protein-rich foods such as meat, poultry, fish, dairy products, and legumes.
Histidine is the amino acid considered essential for adolescents but non-essential for adults, as adolescents require it for growth, whereas adults can synthesize it in their bodies.
The amino acid that is considered essential for adolescents and non-essential for adults is histidine. This is because adolescents require it for growth and it cannot be synthesised in sufficient quantities by their bodies, making it necessary to acquire through diet. In adults, however, the body can synthesize histidine, and thus it is considered non-essential.
Humans need 20 amino acids to synthesize proteins. Of these, some are essential, which means they need to be obtained from the diet, while others are non-essential, as the body can produce them. There are also conditionally essential amino acids which become essential under specific circumstances such as illness or stress.
Proteins are vital for body repair and growth in adolescents, and the ten essential amino acids include histidine. For adults, the synthesis of non-essential amino acids like histidine occurs sufficiently in the body.
