Old French

Etymology

From Late Latin or Vulgar Latin est?, from Latin st?. Forms in -ois-, -ac-, and -ui/-eü-/-i-/-ont originates from Vulgar Latin *stite?, *stati?, and *ste? (perfect *stu?), all come from Latin stit?, statum, and st?. The second- and third-singular indicative present forms indicates that the original stress are always in the last syllable, even being affected by addition of epenthetic *i- before initial consonant clusters involving -s- (stresses are in bold, st?s ? *ist?s ? estas, estais, not *ist?s ? *eistes). Compare with estre, whose later merged and resulting some forms reflecting the forms of ester.

1. to be

     It is butyrate, however, which is the fatty acid of most importance to the colonic epithelial cell. Apart from being an important respiratory fuel for the colonocyte, butyrate has remarkably diverse properties in a wide range of cells.

     Another question to be raised is the possible use of butyrate in the lipogenic pathway. Even though the carbons from butyrate could be incorporated into lipid extracts [12], this incorporation represents less than 1 % of CO₂, and TKB productions.

     To examine the effects of sodium butyrate on virus production, cells were exposed to sodium butyrate at various concentrations and times starting 16 h after transfection.

     Butyrates are four carbon fatty acids first found in butter. Butyrates are formed naturally in the gut by friendly bacteria (probiotics) digesting fibre, such as the fibre in psyllium seed husks.
