**Core Concept**
Semi-essential amino acids, also known as conditionally essential amino acids, are amino acids that can be synthesized by the human body under normal circumstances but may need to be supplemented in times of stress, illness, or certain medical conditions.
**Why the Correct Answer is Right**
The body can synthesize these amino acids from other compounds, but during periods of increased demand, such as during growth, injury, or disease, the body may not be able to produce enough, making them conditionally essential. Examples of semi-essential amino acids include arginine, glutamine, and tyrosine.
