Amino is a social media application originally developed by Narvii, Inc. It was originally created by Yin Wang and Ben Anderson in 2012, and then launched as an app ...
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, ...
The commercial production of amino acids usually relies on mutant bacteria that overproduce individual amino acids using glucose as a carbon source. Some amino acids are produced by enzymatic conversions of synthetic intermediates. 2-Aminothiazoline-4-carboxylic acid is an intermediate in the industrial synthesis of L-cysteine for example.
An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized from scratch by the organism fast enough to supply its demand, and must therefore come from the diet. Of the 21 amino acids common to all life forms, the nine amino acids humans cannot synthesize are valine , isoleucine , leucine , methionine ...
The formation of a peptide bond requires an input of energy. The two reacting molecules are the alpha amino group of one amino acid and the alpha carboxyl group of the other amino acids. A by-product of this bond formation is the release of water (the amino group donates a proton while the carboxyl group donates a hydroxyl). [2]
The N-terminus (also known as the amino-terminus, NH 2-terminus, N-terminal end or amine-terminus) is the start of a protein or polypeptide, referring to the free amine group (-NH 2) located at the end of a polypeptide. Within a peptide, the amine group is bonded to the carboxylic group of another amino acid
In a plant-based diet there is the perceived issue of amino acid content of various individual foods. A satisfying diet however, will include minimum requirements of all essential amino acids. In addition to grains, such as corn, rice, or wheat, vegetable protein also occurs in legumes, which include beans and peanuts.
L-amino acids are the mirror reflection of D-amino acids, and vice versa. In this example, alanine is depicted in the zwitterionic form at physiological pH. D-Amino acids are amino acids where the stereogenic carbon alpha to the amino group has the D-configuration. For most naturally-occurring amino acids, this carbon has the L-configuration.
