Acetate

(Science: biochemistry) a salt or ester of acetic acid, specifically, a synthetic textile fibre made from partially hydrolysed cellulose acetate, or a plastic-like film made from cellulose triacetate.

The terminal hydrogen atom in the molecule is replaced by a metal, for instance copper acetate, or where substitution is by a radical, for instance ethyl acetate.

Re: [molecular bio]calculation

... 1 M potassium phosphate, and a 5 mg/ml stock of cholesterol (mol. wt. 386.7) Acetic acid (CH3COOH) is a liquid at room temperature. When making acetate buffers (as in the question above) you must add specific molar quantities of acetic acid and sodium acetate to achieve the required pH. How ...

Re: Krebs Cycle question

... be impressed with the number of steps. The rate-limiting step for citrate synthase (the mixed condensation reaction between acetyl-CoA and oxaloacetate to form citrate) is the enolization of the acetyl group which then acts as a nucleophile toward bound oxaloacetate. Water--freely available ...
