Understanding Amino Acids: The Basics

What are Amino Acids?

Amino acids are organic compounds that contain both amino (-NH2) and carboxyl (-COOH) functional groups, along with a side chain (R group) specific to each amino acid. These molecules serve as the monomers from which proteins are constructed. Proteins, in turn, perform a vast array of functions within the body, including catalyzing biochemical reactions (enzymes), transporting molecules (hemoglobin), providing structural support (collagen), and regulating gene expression (transcription factors).

The general formula for an amino acid is NH2-CHR-COOH, where R represents the unique side chain that differentiates each amino acid. These side chains vary in size, shape, charge, hydrophobicity, and reactivity, which determine the specific properties and functions of each amino acid and the proteins they form.

Essential vs. Non-Essential Amino Acids

Amino acids are categorized into two main groups: essential and non-essential. The distinction lies in whether the human body can synthesize the amino acid on its own.

• Essential Amino Acids: These cannot be synthesized by the body and must be obtained through the diet. There are nine essential amino acids: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
• Non-Essential Amino Acids: These can be synthesized by the body from other compounds. Examples include alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine. Note that some non-essential amino acids are considered conditionally essential during times of illness or stress.

The Role of Amino Acids in Protein Synthesis

Protein synthesis is the process by which cells create proteins. It involves transcription (copying DNA into RNA) and translation (using RNA to assemble amino acids into a polypeptide chain). The sequence of amino acids in a protein determines its three-dimensional structure and, consequently, its function.

The process occurs in ribosomes, where transfer RNA (tRNA) molecules bring specific amino acids to the ribosome according to the sequence specified by messenger RNA (mRNA). As each amino acid is added, a peptide bond forms between it and the growing polypeptide chain. Once the protein is fully synthesized, it folds into its functional conformation, often with the assistance of chaperone proteins.
