These data suggest that HMG-CoA reductase and Ubiad1 are on the same metabolic pathway to produce CoQ10 as a potent antioxidant molecule which protects cardiovascular tissues during development.
At the same time, a number of cellular molecules called antioxidants, which protect the cell from excessive ROS-induced lipid peroxidation, are also present within the ejaculate [ 16].
Plants are a viable, unlimited source of bioactive molecules, including antimicrobial agents which protect them from microorganism, insects, and predators [ 7– 11].
It was recently shown that bacterial resistance to antibiotics can be mediated as a population-level trait by the secreted signaling molecule indole, which protects any bacterial cells receiving it against the effects of antibiotics (Lee et al. 2010).
Carotenoids are nonenzymatic antioxidants which protect the chlorophyll molecules against oxidative stresses (Halliwell 1987).
HSCs also modulate several molecules to adapt to the hypoxic environment, such as glycolytic and oxidative repair proteins, which protect them from oxygen radicals.
Saliva contains mucins, which protect epithelial cells.
Emollients, which protect your skin.
In contrast to Gram-negative bacteria, the presence of teichoic acids is unique to Gram-positive bacterial cell wall and provides negatively charged sites for cationic QDs along the chain of teichoic-acid molecules, which may protect QDs from aggregation and fluorescence quenching.
For example, the OBP3 gene is a carrier of odor molecules, which can protect odor molecules from enzymatic degradation [ 17, 18].
