Leucine ball and stick model spinning. Leucine (symbol Leu or L) [3] is an essential amino acid that is used in the biosynthesis of proteins.Leucine is an α-amino acid, meaning it contains an α-amino group (which is in the protonated −NH 3 + form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side ...
The Color Association of the United States (CAUS), known until 1955 as the Textile Color Card Association of the United States (TCCA), is an independent color trend forecasting and color consulting service to the business community, known for its textile color swatch book, the Standard Color Reference of America (formerly the Standard Color Card of America).
Asparagine is synthesized by amidation of aspartate, with glutamine donating the NH4. These are nonessential amino acids, and their simple biosynthetic pathways occur in all organisms. Methionine, threonine, lysine, isoleucine, valine, and leucine are essential amino acids in humans and most vertebrates.
Transamination is mediated by several types of aminotransferase enzymes. An aminotransferase may be specific for an individual amino acid, or it may be able to process any member of a group of similar ones, for example the branched-chain amino acids, which comprises valine, isoleucine, and leucine.
Leucine zipper motifs are considered a subtype of coiled coils, which are built by two or more alpha helices that are wound around each other to form a supercoil. Coiled coils contain 3- and 4-residue repeats whose hydrophobicity pattern and residue composition is compatible with the structure of amphipathic alpha-helices.
Minimal essential medium (MEM) is a synthetic cell culture medium developed by Harry Eagle first published in 1959 in Science that can be used to maintain cells in tissue culture. [1] It is based on six salts and glucose described in Earle's salts in 1934: calcium chloride , potassium chloride , magnesium sulfate , sodium chloride , sodium ...
