Which amino acid is considered essential in human diet?
Show answer & explanation
Correct answer: C
Explanation
Answer: Lysine.
Explanation:
The human body requires 20 different amino acids to function smoothly, 9 of which are considered 'essential amino acids.' These are termed 'essential' because our body cannot synthesize them on its own; therefore, it is mandatory to obtain them through our diet. Lysine is one such amino acid, playing a crucial role in muscle building, calcium absorption, and the production of hormones and enzymes. Other essential amino acids include valine, threonine, and tryptophan, among others.
Additional Points:
Non-Essential Amino Acids: Alanine, glycine, and serine fall into the 'non-essential' category because the body can synthesize them on its own.
Sources of Protein: Animal products (such as meat and eggs) are considered 'complete proteins' because they contain all the essential amino acids.
Kwashiorkor: This disease can occur in children due to a severe deficiency of protein and essential amino acids in their diet.
