Order Bioactive Food Components and Nutrients Kit
Bioactive Food Components and nutrients are low molecular weight compounds essential for human health that participate in metabolic reactions, act as cofactors, or serve as structural and signaling molecules. They are usually classified into micronutrients (vitamins and minerals) and bioactive food components.
Key Characteristics
- Molecular weight typically <1000 Da
- Absorbed in the gut, distributed in blood/tissues
- Include vitamins, amino acids, fatty acids, and phytochemicals
Bioactive food components are naturally occurring compounds in foods (often non-essential for basic survival) that exert biological effects on health, including disease prevention, immune support, and metabolic regulation. Unlike essential nutrients, these do not cause deficiency diseases if absent, but they optimize health when present.
Main Categories of Bioactive Food Components
| Class | Examples | Health Effects |
|---|---|---|
| Polyphenols | Flavonoids (quercetin, catechins), phenolic acids, resveratrol | Antioxidant, anti-inflammatory, cardioprotective |
| Carotenoids | Beta-carotene, lutein, lycopene, zeaxanthin | Vision support, antioxidant, may reduce cancer risk |
| Phytosterols | Campesterol, sitosterol | Lower LDL cholesterol, support heart health |
| Organosulfur Compounds | Allicin (garlic), sulforaphane (broccoli) | Detoxification, anti-cancer, antimicrobial |
| Glucosinolates | Found in cruciferous vegetables (e.g., broccoli) | Converted to isothiocyanates, support detox pathways |
| Alkaloids | Caffeine (coffee), theobromine (cocoa), capsaicin (chili) | CNS stimulation, metabolism modulation |
| Saponins | From legumes, ginseng, quinoa | Immune modulation, cholesterol-lowering |
| Prebiotics | Inulin, fructooligosaccharides (FOS), galactooligosaccharides (GOS) | Feed beneficial gut bacteria |
| Probiotics | Live microorganisms (e.g., Lactobacillus, Bifidobacterium) | Gut health, immune balance |
| Peptides & Amines | Bioactive peptides (e.g., from milk, soy), serotonin, dopamine | Blood pressure regulation, neurotransmission |
