Which type of amino acids can be synthesized by the body?

Nonessential amino acids are the type that can be synthesized by the body. These amino acids do not need to be obtained through the diet because the body has the ability to produce them from other compounds. This synthesis occurs through a variety of metabolic pathways, ensuring that the body can maintain adequate levels of these amino acids for various physiological functions, such as protein synthesis and enzyme production.

In contrast, essential amino acids are those that cannot be synthesized by the body and must be obtained from dietary sources. Conditional amino acids, while usually considered nonessential, can become essential under certain conditions such as illness, stress, or trauma, when the body's demand for them exceeds its capacity to produce them. Complete amino acids refer to protein sources that contain all the essential amino acids in adequate amounts, but this term does not relate directly to the body's ability to synthesize amino acids.
