Natural amino acids are organic compounds that contain both amino and carboxylic acid functional groups. They are the building blocks of proteins, and they play a vital role in many biological processes. Although there are over 500 amino acids found in nature, only 22 are commonly incorporated into proteins and are encoded by the genetic code of life. These 22 amino acids are essential for building and maintaining the structure and function of our bodies.
- Essential amino acids: These amino acids cannot be produced by the body and must be obtained through diet. Examples include leucine, isoleucine, valine, lysine, methionine, phenylalanine, threonine, tryptophan, and histidine.
- Non-essential amino acids: These amino acids can be produced by the body from other sources. Examples include alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.
Natural amino acids are found in a wide variety of foods, including meat, poultry, fish, eggs, dairy products, legumes, nuts, and seeds. It's important to consume a balanced diet that includes all of the essential amino acids to ensure optimal health and well-being.
