As both the amine and carboxylic acid groups of amino acids can react to form amide bonds, one amino acid molecule can react with another and become joined through an amide linkage. This polymerization of amino acids is what creates proteins. This condensation reaction yields the newly formed peptide bond and a molecule of water.
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 ...
During translation, amino acids are joined into a linear chain by condensation reactions which create peptide bonds between the carboxyl group of one amino acid and the amino group of an adjacent amino acid. The first and last amino acids in the chain are said to be N-terminal and C-terminal, respectively, in reference to the unbonded amino ...
non-canonical amino acid (ncAA) 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 ...
Amino acids: ala = alanine; arg = arginine; asn = asparagine; Some pathways produce metabolites that are precursors of more than one pathway. Hence, loss of one of these enzymes will lead to a requirement for more than one amino acid. For example: ilv: isoleucine and valine; Nucleotides: gua = guanine; pur = purines; pyr = pyrimidine; thy ...
If amino acids were randomly assigned to triplet codons, there would be 1.5 × 10 84 possible genetic codes. [81]: 163 This number is found by calculating the number of ways that 21 items (20 amino acids plus one stop) can be placed in 64 bins, wherein each item is used at least once. [82]
Sequences are expected to be represented in the standard IUB/IUPAC amino acid and nucleic acid codes, with these exceptions: lower-case letters are accepted and are mapped into upper-case; a single hyphen or dash can be used to represent a gap character; and in amino acid sequences, U and * are acceptable letters (see below). Numerical digits ...
