Question: Amino acids that you obtain from eating foods are classified as?

Disambiguated questions and answers:
context: An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized "de novo" (from scratch) by the organism at a rate commensurate with its demand, and thus must be supplied in its diet. Of the 21 amino acids common to all life forms, the nine amino acids humans cannot synthesize are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine.
question: Amino acids that you must obtain from eating foods are classified as?

context: Six other amino acids are considered conditionally essential in the human diet, meaning their synthesis can be limited under special pathophysiological conditions, such as prematurity in the infant or individuals in severe catabolic distress. These six are arginine, cysteine, glycine, glutamine, proline, and tyrosine. Six amino acids are non-essential (dispensable) in humans, meaning they can be synthesized in sufficient quantities in the body. These six are alanine, aspartic acid, asparagine, glutamic acid, serine, and selenocysteine (considered the 21st amino acid). Pyrrolysine (considered the 22nd amino acid) is not used by humans; thus, it is nonessential.

context: The limiting amino acid is the essential amino acid found in the smallest quantity in the foodstuff, most plant-based foods have a limiting amino acid. This concept is important when calculating animal feeds. A complete protein contains all the essential amino acids in the right balance; meat, milk and eggs are complete protein sources for humans.

Long answers:
long_answer: Amino acids that cannot be synthesized and must be obtained from food are classified as essential amino acids, and if they can be found in the smallest quantity in foods, they are also considered limiting amino acids. Of the 21 amino acids common to all life forms, nine are essential amino acids. A further six amino acids are classified as conditionally essential, meaning that they can be synthesized in a limited way in the body, while the remaining six amino acids are classified as non-essential, meaning that they are synthesized in sufficient quantities in the body.
