Amin acids are used to build

Proteins

Explanation:

Amino acids are the monomers, or the building blocks of proteins. There are 20 different amino acids that can make up proteins. The ribosomes in a cell perform protein synthesis and create proteins by assembling the amino acids, according to the DNA's genetic code. The proteins created are used for structure, growth, repair, maintaining pH, balancing fluids and more. In addition, they can be used as enzymes and hormones.
