Squalene is a linear triterpene formed via the MVA or MEP biosynthetic pathway and is widely distributed in bacteria‚ fungi‚ algae‚ plants‚ and animals. Metabolically‚ squalene is not only used as a precursor in the synthesis of complex secondary metabolites such as sterols‚ hormones‚ and vitamins‚ but also as a carbon source in aerobic and anaerobic fermentation in micro-organisms. Owing to the increasing roles of squalene as an antioxidant‚ anticancer‚ and anti-inflammatory agent‚ the demand for

1. In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces

It may be sore and itchy‚ and you may have it in your armpits as well. The rash has a definite edge‚ and there may be some whitish material on it. It is usually caused by skin-on-skin friction and by Candida fungus or Corynebacterium bacteria‚ both of which like to live in warm‚ moist places. If you are overweight as well as having large breasts‚ the skin crease underneath them is ideal for Candida. Candida also likes skin that has been slightly damaged; this makes it easier
