What is enzymatic modification of DNA?
Restriction analysis
What are the benefits of enzymatic therapy?
"Enzymatic therapy can be beneficial for your health. They offer quick healing and a gentle healing process. However, that is not all. They also have other benefits with different models."
What is the reaction that turns glucose into sodium gluconate?
by enzymatic transfornatiob

factors that influence non enzymatic browning
Types of browning reaction?
non enzymatic and enzymatic
what are the effects of enzymatic browning on fruits and vegetables' sensory qualities?

How do you prevent enzymatic browning in fruits?
Enzymatic browning causes the browning in fruits, (turning pigments brown). As when you cut an apple, or drop and apple; damaging cells. Polyphenol oxidase(tyrosinase) is released by the damaged cells and it oxidizes naturally occurring phenols to guinones.
How sugar affect the browning of apples?
Browning of apples is due to the creation of brown pigments through enzymatic polymerization of polyphenolic (normally colorless) apple compounds.
What is the connection between maraschino cherries and sulfur dioxide?
Sulfur dioxide is a chemical that can be added to cherries and other fruit to prevent browning. In very small amounts, it can inhibits enzymatic browning of polyphenoloxidase, and enzyme responsible for fruit browning.
What chemicals are in the browning apple?
browning is due to oxygen, O2, reacting with chemicals released, breaking down the cells in the fruit. The reaction is called enzymatic oxidation as it is a process catalysed by the enzymes present in the apples
Can sugar prevent apples from browning?
Coating freshly cut apples in sugar or syrup can reduce oxygen diffusion and thus slow the browning reaction. Lemon or pineapple juices, both of which naturally contain antioxidants, can be used to coat apple slices and slow enzymatic browning
Does temperatures influence enzymatic browning?
Temperature does affect enzymatic function - temperature affects the "active site" of the enzyme and so the substrate cannot bind to it anymore (process is called denaturation)
What is the scientific name for natural fruit browning?
The scientific name for natural fruit browning is enzymatic browning. It is a chemical reaction that occurs when fruit is cut or damaged, causing an enzyme called polyphenol oxidase (PPO) to come into contact with oxygen in the air and produce brown-colored pigments.
What are the effects of ascorbic acid and citric acid in browning food?
Covering the food with citric acid prevents browning because the acid reduced the pH below the optimum level for the enzyme (polyphenoloxidase) to catalyze the oxidative enzymatic browning reaction. Covering the food in ascorbic acid also prevents browning because ascorbic acid is an antioxidant which interferes with the browning reaction by preventing the intermediate products from being converted into melanins (the brown pigment).
What do a enzymatic protein do?
enzymatic proteins give you metabolic traits.
