Abbreviation Meaning ā (a with a bar over it) before (from Latin ante) before: A: assessment a.a. of each (from Latin ana ana) amino acids: A or Ala – alanine; C or Cys – cysteine; D or Asp – aspartic acid; E or Glu – glutamic acid; F or Phe – phenylalanine; H or His – histidine; I or Ile – isoleucine; K or Lys – lysine; L or ...
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 ...
Amino acids have zero mobility in electrophoresis at their isoelectric point, although this behaviour is more usually exploited for peptides and proteins than single amino acids. Zwitterions have minimum solubility at their isoelectric point, and some amino acids (in particular, with nonpolar side chains) can be isolated by precipitation from ...
In bioinformatics and biochemistry, the FASTA format is a text-based format for representing either nucleotide sequences or amino acid (protein) sequences, in which nucleotides or amino acids are represented using single-letter codes. The format allows for sequence names and comments to precede the sequences.
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 ...
Protein sequence is typically notated as a string of letters, listing the amino acids starting at the amino-terminal end through to the carboxyl-terminal end. Either a three letter code or single letter code can be used to represent the 22 naturally encoded amino acids, as well as mixtures or ambiguous amino acids (similar to nucleic acid ...
The main thing that a good vacation can do for our mental health is precisely to reduce chronic stress levels. When we are idle, our brain is able to reverse – at least temporarily – the ...
With some exceptions, [1] a three-nucleotide codon in a nucleic acid sequence specifies a single amino acid. The vast majority of genes are encoded with a single scheme (see the RNA codon table ). That scheme is often called the canonical or standard genetic code, or simply the genetic code, though variant codes (such as in mitochondria ) exist.
