Why does acid preserve apples?
the most common acid ingrediants used for preserving foods are vinegar and citric acid from citrus fruit such as lemons. BOTH of these ingredients have a pH level of around two and therefor inhibit the growth of micro organisms and subsequent detrioration of the food
What are the differences between fatty acid synthesis and beta-oxidation?
Fatty acid synthesis is the process of building long-chain fatty acids from acetyl-CoA, while beta-oxidation is the process of breaking down fatty acids to produce acetyl-CoA. Fatty acid synthesis occurs in the cytoplasm, whereas beta-oxidation occurs in the mitochondria. Fatty acid synthesis requires NADPH as a reducing agent, while beta-oxidation generates NADH and FADH2 as reducing agents.
What is oxidation of benzene?
Oxidation of benzene involves the addition of oxygen or removal of hydrogen from benzene molecules. This process typically leads to the formation of products with more oxygen-containing functional groups, such as phenol or benzoic acid. Oxidation of benzene can be catalyzed by various reagents or conditions, such as nitric acid or metal catalysts.
Is squeezing lemon juice on fruit to stop it going brown a chemical reaction?
Squeezing lemon juice on fruit to prevent browning is not a chemical reaction, but rather a physical reaction. The citric acid in the lemon juice slows down the oxidation process that causes the fruit to turn brown by acting as an antioxidant.
Why does lemon juice stop oxidation PS really urgent answer tonight 19th May if poss?
Lemon juice contains carboxylic acids as Citric and Ascorbic acids they form a thin layer of metallic citrate or carboxylate which prevents the absorption of water ,carbondioxide and oxygen so further oxidation of metal becomes stopped.

Why does citric acid prevent oxidation?
Citric acid acts as an antioxidant by chelating with metal ions that catalyze oxidation reactions. This helps inhibit the oxidation process by preventing the metal ions from interacting with other molecules that would lead to oxidation. Additionally, citric acid can also act as a reducing agent, further slowing down the oxidation process.
Why does lemon juice affect an apple from turning brown?
Applying lemon juice to sliced apples helps prevent oxidation.
Why does lemon juice slow down the process of oxidation?
Oxidation is cause by (obviously) the oxygen in the air. When you cut up fruit for instance, the parts without skin which are exposed will turn brown quickly. Squeezing lemon juice over your fruit (apple, pear, banana, ect) will stop oxidation because the juice contains Vitamin C (ascorbic acid). The ascorbic acid reacts with the oxygen preventing the browning on the apple (fruit). In theory, other citric fruits would do the same thing. Whenever making an apple pie (or pear whatever) squeeze a lemon over the pieces as you cut them up (and toss) this will stop the oxidation process while you are cutting up all the fruit.

Fatty acid synthesis requires NADPH as a reducing agent, while beta-oxidation generates NADH and FADH2 as reducing agents.
What is the source of nitric acid?
Nitric acid is typically produced by the oxidation of ammonia with air in the presence of a catalyst at high temperatures. This process creates nitrogen dioxide, which is then dissolved in water to form nitric acid. Additionally, nitric acid can also be produced by the reaction of nitrogen oxides with water.
What is produced by fatty acid oxidation?
Fatty acid oxidation produces energy in the form of ATP, as well as acetyl-CoA molecules which can enter the citric acid cycle to generate more ATP through oxidative phosphorylation. Additionally, the oxidation process generates carbon dioxide and water as byproducts.
What is the chromic acid oxidation mechanism for converting aldehydes?
The chromic acid oxidation mechanism for converting aldehydes involves the aldehyde reacting with chromic acid to form a carboxylic acid. This reaction typically occurs in the presence of sulfuric acid and water. The chromic acid is reduced to chromium(III) during the process.
What is oxidation of benzene?
Oxidation of benzene involves the addition of oxygen or removal of hydrogen from benzene molecules. This process typically leads to the formation of products with more oxygen-containing functional groups, such as phenol or benzoic acid. Oxidation of benzene can be catalyzed by various reagents or conditions, such as nitric acid or metal catalysts.
On a basic level how does fatty acid oxidation work?
Fatty acid oxidation is the process in which fatty acids are broken down by tissues to produce energy. Fatty acids are the residue left from fats being broken down.
What is the oxidation number for hydrochloric acid?
In hydrochloric acid (HCl), the oxidation number of hydrogen is +1 and the oxidation number of chlorine is -1.
How do you convert methanoic acid to ethanoic acid?
Methanoic acid (formic acid) can be converted to ethanoic acid (acetic acid) by oxidation. One common method is to react methanoic acid with a strong oxidizing agent, such as potassium permanganate (KMnO4), in the presence of sulfuric acid (H2SO4). The oxidation process converts the carboxylic acid group in formic acid to form the carboxylic acid group in acetic acid.
