Humans can make ten of twenty of the amino acids in their own body. Since there is a lack of resources they can't make the other ten. They must get these other amino acids from other animals and plants. Meaning that we must eat the right diet to get all of the amino acids. If we do not get even one of all twenty then our body starts to break down and muscles start to degrade. It is essential to eat right.
These are the ten amino acids we can produce: alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine and tyrosine. The amino acids that we need in our diet are arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Since plants can make all twenty amino acids, it is essential to eat your fruits and vegetables.
Amino acids are building blocks for proteins and other macromolecules, but mostly proteins. Proteins are made in every cell through the work of amino acids. The precise amino acid content and the sequence of them in proteins are determined by sequence of the bases in the gene that encodes that protein. Amino acids also make up all DNA and RNA. All amino acids are basically composed the same. They all have the same amino and acid and a CH that connects them. The only thing that differs is the R or Rest of the amino acid. All amino acids are made up of hydrogen, oxygen, carbon, nitrogen, and sulfur.
