Butyric acid (butanoic acid) belongs to a group of short-chain fatty acids and is thought to play several beneficial roles in the gastrointestinal tract. Butyric anion is easily absorbed by enteric cells and used as a main source of energy. Moreover, butyric acid is an important regulator of colonocyte proliferation and apoptosis, gastrointestinal tract motility and bacterial microflora composi...

Dye sensitized solar cells have achieved more than 12% efficiency[1][2] since 1991 when first metal organicphotosensitizer was made by Gratzel based on ruthenium complex[3].Here we discussed the effect ofextended conjugation absorption spectra of photosensitizers[4]. The designed dye molecules are ondonor- π -acceptor model. dyes named as S1 [naphthalene-pyrrole-butanoic acid] and S2[naphthalen...

Cytenamide forms a 1:1 solvate with butyric acid [systematic name: 5H-dibenzo[a,d]cyclo-hepta-triene-5-carboxamide-butanoic acid (1/1)], C(16)H(13)NO·C(4)H(8)O(2). The title compound crystallizes with one mol-ecule of cytenamide and one of butyric acid in the asymmetric unit; these mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds to form an R(2) (2)(8) heterodimer motif. Pairs of adjacen...

DL-2-Hydroxy-(4-methylthio)butanoic acid (HMTBA) is a synthetic source of dietary methionine (Met) widely used in poultry nutrition. HMTBA is transported in the intestinal epithelium by the monocarboxylate transporter 1, after which its biological utilisation relies on its conversion to L-Met. This process involves stereospecific HMTBA oxidation to 2-keto-(4-methylthio)butanoic acid (KMB) and t...
