  2. Amino acid score - Wikipedia

    en.wikipedia.org/wiki/Amino_acid_score

    By using an amino acid score, it can be indicated if a protein will meet all amino acid needs of the body. If the amino acid score meets the required score it will be a completed or ideal protein. To calculate the amino acid score the formula used is, the milligram of limiting amino acid in 1 gram of test protein/ the milligram of that same ...

  3. Amino acid - Wikipedia

    en.wikipedia.org/wiki/Amino_acid

    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] Only these 22 appear in the genetic code of life. [3] [4]

  4. Protein digestibility corrected amino acid score - Wikipedia

    en.wikipedia.org/wiki/Protein_Digestibility...

    This score means, after digestion of the protein, it provides per unit of protein 100% or more of the indispensable amino acids required. The formula for calculating the PDCAAS percentage is: (mg of limiting amino acid in 1 g of test protein / mg of same amino acid in 1 g of reference protein) x fecal true digestibility percentage. [2]

  5. Protein pKa calculations - Wikipedia

    en.wikipedia.org/wiki/Protein_pKa_calculations

    In computational biology, protein pK a calculations are used to estimate the pK a values of amino acids as they exist within proteins.These calculations complement the pK a values reported for amino acids in their free state, and are used frequently within the fields of molecular modeling, structural bioinformatics, and computational biology.

  6. Digestible Indispensable Amino Acid Score - Wikipedia

    en.wikipedia.org/wiki/Digestible_Indispensable...

    Amino acid requirements were determined in two parts. The amino acid distribution of breast milk was used for the 0 to 6 month age range, and existing amino acid data was used for older ages after adjustment for digestibility. The reference amino acid requirements are presented below. [2]: 29

  7. β-Alanine - Wikipedia

    en.wikipedia.org/wiki/Β-Alanine

    β-Alanine (beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon (i.e. the carbon two carbon atoms away from the carboxylate group) instead of the more usual α-carbon for alanine (α-alanine). The IUPAC name for β-alanine is 3-aminopropanoic acid.

  8. N-terminus - Wikipedia

    en.wikipedia.org/wiki/N-terminus

    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

  9. 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. Leucine ...
