Chlorella’s structural makeup shows its exceptional nutritional density. The cell wall has a unique trilaminar sheath. You’ll find an outer layer of sporopollenin paired with an inner wall rich in mannose and chitin-like polysaccharides. This special makeup helps Chlorella protect its valuable nutrients.
Chlorella’s biomass has three main components:
- Proteins (51-60% of dry weight)
- Carbohydrates (12-30%)
- Lipids (4-22%)
The right growing conditions help Chlorella reach protein levels between 43% and 61% by dry weight. The protein profile contains all essential amino acids that humans need. Chlorella packs substantial amounts of arginine (around 3,200 mg/100g dry weight). This amino acid plays a vital role in cellular signaling.
Key active compounds for skin health
Chlorella’s skin-boosting properties come from its variety of bioactive compounds. The carotenoid profile features powerful antioxidants like neoxanthin, cryptoxanthin, beta-carotene, lutein, and zeaxanthin. These compounds protect your skin from aging by a lot.
Chlorella works on skin health through several ways:
- Growth Factors: Natural growth factors (EGF, FGF) stimulate cell division and help repair skin.
- Detoxification Properties: Chlorella binds with heavy metals and toxins naturally. This prevents oxidative stress in skin cells.
- Anti-inflammatory Action: Essential fatty acids and anti-inflammatory components reduce skin inflammation and redness.
The microalgae’s rich vitamin content helps skin health tremendously. You’ll find plenty of:
- B-complex vitamins
- Vitamin A (beta-carotene)
- Vitamin C
- Vitamin E (tocopherols)
These vitamins work together to support collagen production, boost skin hydration, and shield against environmental damage. Chlorella contains more chlorophyll than any other plant. This green pigment acts as a powerful antioxidant that protects and rejuvenates skin.
Chlorella’s polysaccharides show remarkable anti-wrinkle properties. The phenolic compounds work great in sunscreen products. These elements, along with alginate compounds, fight free radicals effectively.
Chlorella takes an all-encompassing approach to skin health with its detailed nutrient profile and bioactive compounds.
