Amino acids are organic compounds that serve as the building blocks of proteins. They play crucial roles in various biological processes and contribute to the overall structure and function of the human body.

The human body requires 20 different amino acids for proper protein synthesis. Out of these, 9 are considered essential, meaning they cannot be produced by the body and must be obtained through diet.

Essential amino acids are the ones that the human body cannot produce and must be obtained from external sources such as food. They are vital for various bodily functions, including muscle synthesis, hormone production, and immune system maintenance.

Foods rich in essential amino acids include animal proteins such as meat, fish, eggs, and dairy products. Plant-based sources like soy, quinoa, and legumes are also good options for obtaining these amino acids.

Insufficient intake of essential amino acids can lead to various health issues, including muscle loss, impaired immune function, fatigue, and poor wound healing. It is essential to ensure an adequate supply of these amino acids through a balanced diet.
