  2. List of medical mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_medical_mnemonics

    This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...

  3. List of chemistry mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

  4. Amino acid - Wikipedia

    en.wikipedia.org/wiki/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]

    Also non-standard amino acid. Any amino acid , natural or artificial, that is not one of the 20 or 21 proteinogenic amino acids encoded by the standard genetic code . There are hundreds of such amino acids, many of which have biological functions and are specified by alternative codes or incorporated into proteins accidentally by errors in ...

  6. Protein metabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_metabolism

    Ribosomes translate the codons to their respective amino acids. [1] In humans, non-essential amino acids are synthesized from intermediates in major metabolic pathways such as the Citric Acid Cycle. [2] Essential amino acids must be consumed and are made in other organisms. The amino acids are joined by peptide bonds making a polypeptide chain.

  7. Amino acid synthesis - Wikipedia

    en.wikipedia.org/wiki/Amino_acid_synthesis

    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.

  8. Norepinephrine - Wikipedia

    en.wikipedia.org/wiki/Norepinephrine

    Thus the direct precursor of norepinephrine is dopamine, which is synthesized indirectly from the essential amino acid phenylalanine or the non-essential amino acid tyrosine. [12] These amino acids are found in nearly every protein and, as such, are provided by ingestion of protein-containing food, with tyrosine being the most common.

  9. Non-proteinogenic amino acids - Wikipedia

    en.wikipedia.org/wiki/Non-proteinogenic_amino_acids

    Lysine. Technically, any organic compound with an amine (–NH 2) and a carboxylic acid (–COOH) functional group is an amino acid. The proteinogenic amino acids are a small subset of this group that possess a central carbon atom (α- or 2-) bearing an amino group, a carboxyl group, a side chain and an α-hydrogen levo conformation, with the exception of glycine, which is achiral, and proline ...
