Aminokarbonhappeides

Aminokarbonhappeides, also known as amino acids, are organic compounds that are the building blocks of proteins. They consist of an amino group (-NH2), a carboxyl group (-COOH), and a unique side chain (R) that varies among different amino acids. There are 20 standard amino acids that are commonly found in proteins, each with its own unique side chain. These amino acids are classified into four groups based on the properties of their side chains: nonpolar, polar, acidic, and basic.

Amino acids can exist in two forms: the L-isomer, which is found in proteins, and the D-isomer, which is less common. The L-isomer is so named because it rotates plane-polarized light to the left. The structure of amino acids allows them to form peptide bonds, which link them together to form proteins. This process occurs through a condensation reaction, where the carboxyl group of one amino acid reacts with the amino group of another, releasing a water molecule.

Amino acids are essential for various biological processes, including metabolism, enzyme function, and hormone synthesis. They are also important in nutrition, as they are the primary source of nitrogen for the body. Amino acids can be obtained through the diet or synthesized by the body. Essential amino acids are those that cannot be synthesized by the body and must be obtained through the diet. Nonessential amino acids can be synthesized by the body or obtained through the diet.
