What is an essential amino acid?
What are the essential amino acids?
Essential amino acids An amino acid that must be obtained from the diet so that the body can synthesize vital proteins. The nine essential amino acids are: .
isoleucine .
leucine .
lysine .
methionine .
phenylalanine .
threonine .
tryptophan .
valine .
histidine Five …others, arginine, cysteine, glycine, glutamine and tyrosine, are considered conditionally essential - meaning that they are produced by most people, but must be supplied to those who are incapable of producing them. The essential amino acids must be available in the body simultaneously and in the correct proportions for protein synthesis to occur. One of the problems with some crash diets is that they do not provide enough essential amino acids and, in some extreme cases, have resulted in death. (MORE)
Examples of essential amino acid?
Essential amino acids cannot be made by the body, so they must be taken in as nutrients. These include leucine, isoleucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine and histidine.
What are essential amino acids?
An amino acid that cannot be synthesised by an organism and therefore must be supplied by the diet is called an essential amino acid. Humans can produce 12 of the 20 amino acids. The others must be supplied in the food. These are called essential amino acids. The body also doesn't store the excess a…mino acids so they must be eaten in food every day. There are 8 essential amino acids in adults and 9 in children. Examples of these are tryptophan, lysine and valine. Some amino acids can be changed into others as required but some cannot be made this way and therefore must be taken through food. Most foods of the animal origin (meat, eggs, and milk) contain all the different amino acids that we need. .
When we eat proteins, the molecules are broken down into their constituent amino acids in the digestive system. The amino acids are absorbed into the blood and then taken via the liver and other parts of the body to individual cells. Here they are used to synthesise whichever particular proteins are required. .

Which amino acid is classified as a conditionally essential amino acid?
The conditionally essential amino acids in humans are the amino acids arginine, cysteine, glycine, glutamine, histidine, proline, serine and tyrosine. They are considered conditionally essential, which means they are not normally required in the diet, but must be supplied as a supplement to specific… populations that do not synthesize it in adequate amounts. An example would be with the disease phenylketonuria (PKU). Individuals living with PKU must keep their intake of phenylalanine extremely low to prevent mental retardation and other metabolic complications. However, they cannot synthesize tyrosine from phenylalanine, so tyrosine becomes essential in the diet of PKU patients. (MORE)
