1. Amino acid

   Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code.Amino acids can be classified according to the locations of the core structural functional groups, as alpha- (α-), beta- (β-), gamma- (γ-) or delta- (δ-) amino acids; other categories relate to polarity, ionization, and side chain group type (aliphatic, acyclic, aromatic, containing hydroxyl or sulfur, etc.). In the form of proteins, amino acid residues form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life on Earth and its emergence.

1. amino acid

   Amino acid is a type of organic compound that combines to form proteins. It contains an amino group (-NH2), a carboxyl group (-COOH), and a side chain that varies between different amino acids. The basic structure of an amino acid allows it to bind to other amino acids, forming chains known as polypeptides, which are used by the body to construct proteins. There are 20 standard amino acids that can be synthesized by the human body, and others that cannot be are known as essential amino acids and must be obtained through diet.

1. Amino acid

   Amino acids are biologically important organic compounds made from amine and carboxylic acid functional groups, along with a side-chain specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, though other elements are found in the side-chains of certain amino acids. About 500 amino acids are known and can be classified in many ways. Structurally they can be classified according to the functional groups' locations as alpha-, beta-, gamma- or delta- amino acids; other categories relate to polarity, pH level, and side chain group type In the form of proteins, amino acids comprise the second largest component of human muscles, cells and other tissues. Outside proteins, amino acids perform critical roles in processes such as neurotransmitter transport and biosynthesis. Amino acids having both the amine and carboxylic acid groups attached to the first carbon atom have particular importance in biochemistry. They are known as 2-, alpha-, or α-amino acids; often the term "amino acid" is used to refer specifically to these. They include the 23 proteinogenic amino acids which combine into peptide chains to form the building blocks of a vast array of proteins. These are all L-stereoisomers although a few D-amino acids occur in bacterial envelopes and some antibiotics. 20 of the 23 proteinogenic amino acids are encoded directly by triplet codons in the genetic code and are known as "standard" amino acids. The other three are pyrrolysine, selenocysteine, and N-Formylmethionine. For example, 25 human proteins include selenocysteine in their primary structure, and the structurally characterized enzymes employ Sec as the catalytic moiety in their active sites. Pyrollysine and selenocysteine are encoded via variant codons; for example, selenocysteine is encoded by stop codon and SECIS element. Codon–tRNA combinations not found in nature can also be used to "expand" the genetic code and create novel proteins known as alloproteins incorporating non-proteinogenic amino acids.

1. Amy Adams:

   Tart cherry juice can increase our bodies' ability to use tryptophan, which is an amino acid linked to sleep. Tart cherry also has a high melatonin concentration, research says 8 oz of tart cherry juice in the morning and nighttime for as little as two weeks can significantly reduce insomnia.
