10 Questions
Which type of amino acids can't be synthesized in the body and must be obtained from the diet?
Essential amino acids
Which amino acids are formed in the body but not in sufficient amount for body requirements, especially in children?
Semi-essential amino acids
Which type of amino acids can be synthesized in the body?
Non-essential amino acids
Which of the following are metabolic intermediates in urea biosynthesis?
Nonstandard amino acids
Which amino acid derivatives act as neurotransmitters and mediate parts of the immune response?
Histamine
What are essential amino acids and why are they important?
Essential amino acids are 10 in number and cannot be synthesized in the body, so they must be obtained from the diet. Their deficiency can affect growth, health, and protein synthesis.
What are semi-essential amino acids and how are they formed?
Semi-essential amino acids are formed in the body but not in sufficient amounts for body requirements, especially in children. Examples include arginine and histidine.
What are non-essential amino acids and how are they different from essential and semi-essential amino acids?
Non-essential amino acids can be synthesized in the body, unlike essential and semi-essential amino acids.
What are nonstandard amino acids and what distinguishes them from other amino acids?
Nonstandard amino acids occur naturally in cells but do not participate in peptide synthesis. Many are metabolic intermediates, such as ornithine and citrulline, which are intermediates in urea biosynthesis.
What are amino acid derivatives and what important biological functions do they serve?
Amino acid derivatives are chemical derivatives of amino acids with important biological functions. Examples include catecholamines, GABA, dopamine, and histamine, which act as neurotransmitters and mediate parts of the immune response.
Test your knowledge of essential, semi-essential, and non-essential amino acids with this quiz. Learn about the 10 essential amino acids crucial for a healthy diet and the impact of their deficiency on growth and protein synthesis. Explore the semi-essential amino acids and their role, especially in children, and understand the non-essential amino acids that can be synthesized in the body.
