Crossword clues for leucine
The Collaborative International Dictionary
Leucine \Leu"cine\ (l[=oo]"s[=e]n), Leucin \Leu"cin\(l[=u]"s[i^]n), n. [Gr. leyko`s white.] (Physiol. Chem.) a naturally occurring alpha-amino acid ( (CH3)2CH.CH2.CH(NH2)-COOH), one of the building units of almost all proteins of living organisms, both animal and vegetable. It is one of the essential amino acids (not synthesized by the human body, a required component for proper nutrition), and is hydrophobic in character when bound in proteins. In isolated form it is a white, crystalline, zwitterionic substance formed, e. g. by the decomposition of proteins by pancreatic digestion, by the action of boiling dilute mineral acid, or by putrefaction. Chemically it is to be considered as amido-caproic acid. It occurs as two optical isomers, the L- and D-forms. The L-form, L-leucine, is the natural form, present in most proteins.
Wiktionary
n. (context amino acid English) An essential amino acid, C6H13NO2, isomeric with isoleucine, found in most animal proteins; it is essential for growth in children.
WordNet
n. a white crystalline amino acid occurring in proteins that is essential for nutrition; obtained by the hydrolysis of most dietary proteins
Wikipedia
Leucine (abbreviated as Leu or L; encoded by the six codons UUA, UUG, CUU, CUC, CUA, and CUG) is an α-amino acid used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO form under biological conditions), and an isobutyl side chain, classifying it as a nonpolar (at physiological pH) amino acid. It is essential in humans—meaning the body cannot synthesize it and thus must obtain from the diet.
Leucine is a major component of the subunits in ferritin, astacin, and other "buffer" proteins.
Usage examples of "leucine".
Five amino acids were formed- alanine, valine, leucine, glycine, and hydrogen cyanide.
Since most of the abbreviations consist of the first three letters of the name, they are not difficult to memorize: glycine gly alanine ala valine val leucine leu asparagine asp'Ntb aspartic acid asp glutamine ghrNH2 glutamic acid glu THE HUMAN BRAIN isoleucine proline phenylalanine tyrosine tryptophan serine threonine ileu pro phe tyr try ser thr lysine histidine lys his arginine methionine arg met cystine cysteine cy-S-cy-SH Of the abbreviations that are more than the first three letters of the names, ileu, asp-NH2, and ghrNH2 should be clear.
But it would give a rough percentage composition: so much valine, so much arginine, so much cystine and proline and leucine.
