3. The R group of the amino acid Serine is -CH2-OH. The R group of the amino acid Alanine is -CH3.Where would these amino acids be mostly likely located within a globular protein in aqueous solution? B A Serine would be in the interior, and alanine would be on the exterior of the...
The analytical methods using OPA have been reported for pre- and postcolumn derivatization of amino acids. These methods are very sensitive and afford detection as low as 25 fmol. Ellman's reagent, 5,5′-dithiobis(2-nitrobenzoic acid) (DTNB), produces 2-nitro-5-sulfhydrylbenzoic acid by the...
and two formulas for impaired metabolism of amino acids (one year and older), representing 40% of the total; 65 were complete food formulas, representing 32% of the total, including 11 complete food formulas (1-10 years) and 54 complete food formulas (over 10 years old); only...
Biomass-derived cysteine was used as a sustainable sulfur source for the synthesis of rare sulfur-containing amino acids, such as L-ergothioneine (4), which might be a new vitamin, and various L- or D-2-thiohistidine compounds. Key in this simple, one-pot two-step procedure in water is...
In patients with severe or very severe hypertriglyceridemia, a fibrate can be used as a first-line agent for reduction of triglycerides in patients at risk for triglyceride-induced pancreatitis. Three drug classes (fibrates, niacin, n-3 fatty acids) alone or in combination with statins may be ...
A method is presented by which the site of primary attachment of the amino acids with respect to the 2′- or 3′-hydroxyl group of the terminal adenosine of E. coli tRNAs can be determined. It is found that the aminoacyl-tRNA synthetases (EC 6.1.1.-) with specificity for Arg, Asn, ...
d-amino acids endow peptides with diverse, desirable properties, but the post-translational and site-specific epimerization of l-amino acids into their d-counterparts is rare and chemically challenging. Bottromycins are ribosomally synthesized and post-translationally modified peptides that have overcome...
