It contains four iron-containing heme groups that allow the enzyme to react with hydrogen peroxide. The optimum pH for human catalase is approximately 7, [8] and has a fairly broad maximum: the rate of reaction does not change appreciably between pH 6.8 and 7.5. [9] The pH optimum for other catalases varies between 4 and 11 depending on the ...
2. Lettuce. Water Content: 95% Lettuce, known as the "queen of the salad plants," packs a punch with fiber, vitamins A, C, and K, and folate. Its high water content keeps you hydrated and helps ...
Catalases are enzymes that catalyse the conversion of hydrogen peroxide to water and oxygen, using either an iron or manganese cofactor. [104] [105] This protein is localized to peroxisomes in most eukaryotic cells. [106] Catalase is an unusual enzyme since, although hydrogen peroxide is its only substrate, it follows a ping-pong mechanism.
Bacillus subtilis (/ b ə ˈ s ɪ l. ə s s u b ˈ t iː. l i s /), [3] [4] known also as the hay bacillus or grass bacillus, is a gram-positive, catalase-positive bacterium, found in soil and the gastrointestinal tract of ruminants, humans and marine sponges.

Lactiplantibacillus plantarum (formerly Lactobacillus arabinosus and Lactobacillus plantarum) [3] is a widespread member of the genus Lactiplantibacillus and commonly found in many fermented food products as well as anaerobic plant matter. [4] L. plantarum was first isolated from saliva. Based on its ability to temporarily persist in plants ...
Vitamin C (ascorbic acid) is a water-soluble compound that fulfills several roles in living systems. Sources include citrus fruits (such as oranges, sweet lime, etc.), green peppers, broccoli, green leafy vegetables, black currants, strawberries, blueberries, seabuckthorn, raw cabbage and tomatoes.
Myricetin is a member of the flavonoid class of polyphenolic compounds, with antioxidant properties. [1] Common dietary sources [2] include vegetables (including tomatoes), fruits (including oranges), nuts, berries, tea, [3] and red wine.
