10193-36-9 | Silicic Acid

Chemical type

• Silicon compound (non-essential nutrient)
• Metalloid hydroxide

^[1]

• Inorganic acid

^[2]

Key properties

• Transported specifically by NIP III group
• Accumulates in silicon-accumulating species
• Modulates pore diameter for selectivity

^[1]

• Primary bioavailable form of silicon for plants
• Forms protective silicon deposits on leaf surfaces
• Non-toxic and safe for food applications
• Enhances antioxidant enzyme activities (SOD by 74-383%, CAT, POD)
• Reduces bacterial load by 83% and alters microbial community
• Maintains nutritional quality (increases chlorophyll by 38%, vitamin C by 13%)
• Reduces weight loss (to 5% vs. 16% in controls)
• Lowers nitrite levels by 91%

^[2]

• Enhances tolerance to osmotic, saline, and thermal stress
• Improves structural integrity and defense
• Substrate for engineering stress-resistant crops

^[1]

• Post-harvest immersion treatment for produce
• Extends shelf life of lettuce, cherry tomatoes, and grapes
• Inhibits microbial spoilage and oxidation
• Broad applicability to vegetables and fruits

^[2]

Classification by use

• Solutes transported by AQPs for structural support
• Chemicals in abiotic stress adaptation

^[1]

• Chemicals used in food preservation
• Green and non-toxic preservatives
• Plant stress and spoilage mitigators
