Alternative biochemistry. Silicon-based life. Like carbon, silicon can create molecules that are sufficiently large to carry biological information; however, the scope of possible silicon chemistry is far more limited than that of carbon. Silicon dioxide biochemistry. Non-water solvents. Silicon dioxide -based life.

Other colors used are green for stevia. [1] A sugar substitute is a food additive that provides a sweetness like that of sugar while containing significantly less food energy than sugar-based sweeteners, making it a zero-calorie (non-nutritive) [2] or low-calorie sweetener. Artificial sweeteners may be derived through manufacturing of plant ...
