Amínósýranna

Amínósýranna, also known as amino acids, are organic compounds that combine to form proteins. They are the building blocks of life, essential for virtually all biological processes. Each amino acid has a central carbon atom bonded to an amino group (–NH2), a carboxyl group (–COOH), a hydrogen atom (–H), and a side chain (R-group). This side chain is what differentiates one amino acid from another and determines its unique properties.

There are twenty standard amino acids that are commonly found in proteins, and these are often referred to as the proteogenic amino acids. These twenty can be categorized based on the properties of their side chains, such as being polar, nonpolar, acidic, or basic. In addition to these twenty, there are also non-proteinogenic amino acids that have various roles in biological systems but are not incorporated into proteins.

Amino acids are linked together by peptide bonds to form long chains called polypeptides. These polypeptides then fold into specific three-dimensional structures to create functional proteins. The sequence of amino acids in a polypeptide chain is crucial for determining the protein's final structure and function. Proteins perform a vast array of roles in the body, including acting as enzymes, structural components, hormones, and antibodies.

The human body can synthesize some amino acids on its own, which are known as non-essential amino acids. However, others cannot be synthesized and must be obtained from the diet; these are called essential amino acids. Consuming a balanced diet that includes a sufficient intake of essential amino acids is vital for maintaining health and proper bodily function. They play a role in muscle growth, tissue repair, neurotransmitter synthesis, and energy production.
