Alanine is a non-essential amino acid, meaning the body can produce it on its own. It plays a crucial role in protein synthesis and is involved in the metabolism of sugars and organic acids. Alanine is found in many protein-rich foods, such as meat, fish, eggs, and dairy products. In addition to its role in building proteins, alanine helps regulate blood sugar levels by converting into glucose when needed. It also supports the immune system and helps in the production of antibodies. Overall, alanine is vital for maintaining various bodily functions and overall health.
