Popular questions
Is benzoic acid soluble in water?
Only sparingly—about 3 g per liter at room temperature; its solubility increases in hot water and it dissolves readily in many organic solvents.
Is benzoic acid polar?
It has a polar carboxyl group but a nonpolar aromatic ring, so overall it’s only weakly polar; its benzoate salt is much more polar and water‑soluble.
Is benzoic acid a strong acid?
No—it's a weak acid, with a pKa of about 4.2.
What is the melting point of benzoic acid?
About 122–123 °C (251–253 °F).
Is benzoic acid bad for you?
At approved food levels it’s considered safe, with an ADI of 0–5 mg/kg body weight/day; some people may experience irritation or hypersensitivity, and benzene formation in certain acidic drinks is monitored and kept very low.
What does glucose oxidase do?
It’s an enzyme that oxidizes glucose to D-glucono-delta-lactone (which becomes gluconic acid) while producing hydrogen peroxide and consuming oxygen; in foods it acts as an oxygen scavenger/antioxidant and can strengthen dough.
Cytochrome oxidase is used in which stage of the aerobic respiration of glucose?
Cytochrome c oxidase works in the electron transport chain (oxidative phosphorylation), the final stage of aerobic respiration; this is a different enzyme from the food additive glucose oxidase (E1102).
Glucose oxidase produces what?
Hydrogen peroxide and D-glucono-delta-lactone (which hydrolyzes to gluconic acid), while consuming oxygen.
How does glucose oxidase work?
It is an FAD-dependent oxidoreductase that binds beta-D-glucose, oxidizes it to D-glucono-delta-lactone, and reduces oxygen to hydrogen peroxide—removing oxygen and generating a mild antimicrobial oxidant.
How much hydrogen peroxide does glucose oxidase produce?
Stoichiometry is 1 mole of H2O2 per mole of glucose oxidized (about 34 mg H2O2 per mmol of glucose); in foods the actual amount formed depends on available glucose and oxygen and may be further decomposed or consumed.
