Which disinfectant does not act by disrupting the plasma membrane?
Hydrogen peroxide is a disinfectant that does not primarily act by disrupting the plasma membrane. Instead, it exerts its antimicrobial effects by generating free radicals that damage intracellular components and disrupt cellular function.
Why do amino acids act as free radical scavengers and what is the mechanism?
Amino acids act as free radical scavengers due to their ability to donate hydrogen atoms to neutralize and stabilize free radicals by forming a stable radical intermediate. This mechanism involves the amino acid donating a hydrogen atom to the free radical, forming a new radical intermediate which is less reactive and no longer causes cellular damage.
Does selenium act as an antioxidant?
Yes, selenium is an essential mineral that functions as an antioxidant in the body. It helps protect cells from damage caused by free radicals and supports the immune system. Consuming adequate amounts of selenium through diet or supplements is important for overall health.
Plant adaptations include the development of water-resistant a.chlorophyll b.spores c.binomial nomenclature d.carotenoids?
d. carotenoids Carotenoids are a type of pigment found in plants that can help provide protection against excess light and act as antioxidants. They can also play a role in attracting pollinators or dispersers.
Vitamin e serves as?
Vitamin E serves as an antioxidant that helps protect cells from damage caused by free radicals. It also supports immune function and skin health, and may help with heart health by preventing the oxidation of LDL cholesterol.
What are antioxidants?
According to the American Heritage Dictionary an antioxidant is a molecule that inhibits oxidation, which produces free radicals, which damages or kills cells, which are the building blocks of body. Antioxidants neutralize free radicals by giving them one of their own electrons. The antioxidant molecules don't become free radicals themselves by losing an electron because they are stable in either form (oxidized or reduced). They act as scavengers, helping to prevent cell and tissue damage that could lead to disease. Your cells produce the antioxidant enzymes glutathione, catalase, superoxide dismutase (SOD), and some others which neutralize free radicals naturally in the cell, but due to oxidative stress, your body may not be able to produce enough of these enzymes, especially as you age. Vitamins C and E, carotenoids and selenium are antioxidants.
How can antioxidant act as antiaging agent?
Antioxidants help to neutralize harmful free radicals in the body, which can damage cells and accelerate aging. By reducing the oxidative stress caused by free radicals, antioxidants can help to prevent premature aging of the skin and other organs. Regular intake of antioxidant-rich foods or supplements can support healthy aging and maintain youthful skin appearance.
What are vitamins used for in the human body?
Vitamins have differenct functions. They regulate the biochemical reactions(metabolism),helps in bones,tooth and blood cells formation,act as antioxidants to kill free radicals(keeps you young!),boosting immunity, preventing from cancer etc..
What is A carotenoid is a yellow-orange pigment that absorbs light.?
Carotenoids are a group of yellow-orange pigments found in fruits and vegetables that help plants absorb light for photosynthesis. They also act as antioxidants in the human body, helping to protect cells from damage caused by free radicals. Some common carotenoids include beta-carotene, lutein, and lycopene.
Why was Abraham Lincoln against the civil rights act?
We are free atlast
What is the difference between a reducing agent and an antioxidant?
A reducing agent is a chemical compound that donates electrons to another substance during a chemical reaction, while an antioxidant is a molecule that can prevent or slow down the oxidation of other molecules by reducing the production of free radicals. Essentially, all antioxidants are reducing agents, but not all reducing agents necessarily act as antioxidants.

Are antioxidants vitamins?
Vitamin C & E act as a anti oxidants. Vitamin C occurs naturally in citrus fruits, peppers, leafy greens, melons and berries. Natural vitamin E, also known as d-alpha tocopopherol, offers powerful antioxidant protection. Nuts, seeds, vegetable oils, wheat germ, apricots and fortified cereals are most reliable dietary sources of vitamin E
While a number of compounds can act as antioxidants the major cellular antioxidant in the body is?
glutathione
