essential amino acids
The 9 essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids cannot be produced by the body and must be obtained from the diet.
Isoleucine, leucine, lysine, methionine, phenylalanine, and threonine are known as essential amino acids. These amino acids cannot be synthesized by the human body and must be obtained through diet. They play crucial roles in protein synthesis, metabolism, and various bodily functions. Essential amino acids are vital for growth, repair, and overall health.
In E. coli, the inhibition mechanisms of amino acid biosynthesis involve feedback inhibition. For L-valine, L-isoleucine, and L-leucine biosynthesis, an intermediate product (e.g., alpha-keto acid) typically acts as an inhibitor. L-lysine biosynthesis is inhibited by lysine itself, while threonine biosynthesis is feedback inhibited by isoleucine. Phenylalanine biosynthesis can be inhibited by accumulating levels of phenylalanine. Selenium-methionine incorporation can also be regulated through feedback inhibition mechanisms.

There is no precise number of essential amino acids, but the usual numbers given are nine or ten. The following nine must be in the diet: histidine isoleucine leucine lysine methionine phenylalanine threonine tryptophan valine In addition, children need arginine in their diet, as they do not make as much as they need. Some individuals may have further dietary requirements. For example, people with phenylketonuria are unable to convert phenylalanine into tyrosine, and therefore need tyrosine in their diet.

My information lists ten - lysine, tryptophan, valine, histidine, leucine, isoleucine, phenylalanine, threonine, methionine, and arginine.
Eight amino acids are generally regarded as essential for humans: phenylalanine, valine, threonine, tryptophan, isoleucine, methionine, leucine, and lysine. Cysteine (or sulphur-containing amino acids), tyrosine (or aromatic amino acids), histidine and arginine are additionally required by infants and growing children.

the 20 standard amino acids that build up a protein can be classified as 1)Non polar, 2) Uncharged polar and 3)Charged polar. the names are as follows:1) Non-Polar: Glycine, alanine, valine, leucine, isoleucine, methionine, proline, phenylalanie, tryptophan.2) Uncharged polar: Serine, threonine, cytoseine, tyrosine, aspargine, glutamine.3) Charged polar: Aspartate, glutamate, histidine, lysine and arginine.
There are nine essential amino acids: histidine (essential for children), isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These amino acids must be supplied by food; the body cannot make them.
Well, honey, albumin is a protein made up of a whole bunch of amino acids. We're talking about a mix of alanine, arginine, aspartic acid, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine. So, basically, it's a protein party with all these amino acids strutting their stuff in albumin.
