'''Proteins''' are complex organic compounds whose basic structure is a primary chain of amino acids covalently bonded via [[peptide bonds]] and folded into a certain shape. This tertiary fold dictates the function of the protein within the organism. They can take on many forms and perform distinct functions including (but certainly not limited to) structural, enzymatic, information storage, intracellular signaling, and transportation roles. In terms of structure, proteins are important in the construction and integrity of different body tissues including connective and muscular, as well as endocrine/exocrine glands. <ref> http://www.hsph.harvard.edu/nutritionsource/protein.html </ref>

===Synthesis===

Proteins are synthesized by cytoplasmic structures composed of catalytic rRNA and proteins called [[ribosomes]]. Ribosomes translate information coded in mRNA (transcribed from genomic DNA, specific regions known as [[genes]]) after editing and manipulation by nuclear [[spliceosomes]]. The nascent protein is elongated in the ribosome through addition of different amino acids specified by codons (sets of three nucleotides) in the mRNA molecule. The formation of the protein chain requires the codon, a molecule of transfer RNA (tRNA) charged with a particular amino acid, and the tRNA's anti-codon. A molecule of water is expelled after each peptide bond is formed, hence the name "condensation reaction".
