Name classification and characteristics of 20 amino acids that make up human protein

It is known that there are 20 kinds of basic amino acids, (Twenty amino acids are glycine, alanine, valine, leucine, isoleucine, methionine (methionine), proline, tryptophan, serine, tyrosine, cysteine Twenty kinds of acid, phenylalanine, asparagine, glutamine, threonine, aspartic acid, glutamic acid, lysine, arginine and histidine are the proteins that make up the living body The major units of the 21st and 22nd amino acids, selenocysteine and pyrrolysine, are encoded by the usual stop codons UGA and UAG, respectively, which occur in a few proteins)including 8 kinds of amino acids: lysine, threonine, leucine, isoleucine, valine, methionine, tryptophan, and phenylalanine, which the human body cannot manufacture by itself. , which we call essential amino acids, need to be provided by food. In addition, the human body's ability to synthesize arginine and histidine is not enough to meet its own needs, and it needs to take part of it from food, which we call semi-essential amino acids. The rest of the ten amino acids the human body can make by themselves, which we call non-essential amino acids.
