Amino acids are the building blocks of one of our fundamental nutrients, proteins, which are commonly found throughout the human body. There are different types of amino acids present in the human body. Of all the different amino acids, only 20 contribute to the formation of the structure of proteins. Amino acids are essential for all bodily functions, such as digestion, liver function, or wound healing. Amino acids maintain skin, ligaments, muscles, tendons, hair, and nails. They also contribute to the production of hormones, as well as neurotransmitters and enzymes. Apart from that, they also serve as a source of energy, as well as a nutrient that produces carbohydrates and lipids. The richest source of essential amino acids is animal foods, while plant foods do not contain all of them.
