2. Paul Bragg - Wikipedia

   en.wikipedia.org/wiki/Paul_Bragg

   Paul Chappuis Bragg (February 6, 1895 – December 7, 1976) was an American alternative health food advocate and fitness enthusiast. [1] Bragg's mentor was Bernarr Macfadden. [1] He wrote on subjects such as detoxification, dieting, fasting, longevity, orthopathy and physical culture. Medical experts criticized Bragg as a food faddist and ...

3. Amino acid - Wikipedia

   en.wikipedia.org/wiki/Amino_acid

   Amino acid. Structure of a typical L -alpha-amino acid in the "neutral" form. Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2]

4. Branched-chain amino acid - Wikipedia

   en.wikipedia.org/wiki/Branched-chain_amino_acid

   A branched-chain amino acid (BCAA) is an amino acid having an aliphatic side-chain with a branch (a central carbon atom bound to three or more carbon atoms). Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine, and valine. [1] Non-proteinogenic BCAAs include 2-aminoisobutyric acid and alloisoleucine. The three ...

5. Protein primary structure - Wikipedia

   en.wikipedia.org/wiki/Protein_primary_structure

   Protein primary structure is the linear sequence of amino acids in a peptide or protein. [1] By convention, the primary structure of a protein is reported starting from the amino -terminal (N) end to the carboxyl -terminal (C) end. Protein biosynthesis is most commonly performed by ribosomes in cells.

6. Essential amino acid - Wikipedia

   en.wikipedia.org/wiki/Essential_amino_acid

   Essential amino acid. 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 ...

7. Amino acid synthesis - Wikipedia

   en.wikipedia.org/wiki/Amino_acid_synthesis

   Amino acid biosynthesis is the set of biochemical processes (metabolic pathways) by which the amino acids are produced. The substrates for these processes are various compounds in the organism 's diet or growth media. Not all organisms are able to synthesize all amino acids. For example, humans can synthesize 11 of the 20 standard amino acids.
