SUGAR MOLECULES/CHEMICAL FORMULA



Sugar chemical Formula
Sugar, also known as saccharose, sucrose or by the chemical name α-D-glucopyranosyl, is a carbohydrate extensively used in the food industry and homemade food preparation.
Formula and structure: The sucrose chemical formula is C12H22O11 and the molar mass is 342.30 g mol-1. The structure is a disaccharide formed by two subunits, one of glucose and one unit of fructose. The crystal structure is monoclinic. Its chemical structure can be written as below, in the common representations used for organic molecules.
Physical properties: Sucrose is white, odorless and sweet taste crystalline solid. It is highly soluble in water (2000 g /L) and other polar solvents. Its density is 1.587 g mL-1. The sucrose doesn't have melting point, it decomposes up to 186 C.
Chemical properties: The sucrose is formed by two subunits of other very known sugars: fructose and glucose. One of them is a six member heterocycle (glucose ring) while the another one is a five member heterocycle (fructose ring), both rings are linked by a glycosidic linkage. Its highly solubility in water is due to the presence of several hydroxyl groups in the molecules, which made of this compound a polar structure. Another important characteristic is, sucrose doesn't have melting point, instead it decomposes up to 186 C, forming caramel in a reaction that is very used by the food industry.
Uses: Sucrose is the main ingredient of the modern sweet production. It is used in houses for the preparation of desserts and another important use is as preservation agent in the food industry. It can also be added in some medicines, pills and syrups.
Health effects / safety hazards: Sugar is not a dangerous substance, however is associated to multiple health problems when consumed in excess, for example: Tooth decay, high glycemic index, diabetes and obesity.

THE EGG FLOAT TEST!

The Egg Float Test Together, and with the help of a small bowl of water, let’s save millions of perfectly good eggs from being thrown away. Egg shells are very slightly porous. Over time, air seeps into the shell making it lighter than it was, and, when it is old and no longer good to eat, it floats. Hence, the egg float test.

GOOGLE FORMS!

DAY 10 /30 Challenge. #e-learning, distance learning & remote learning. The next update for teachers’  where we can use “GOOGLE FORMS” Students and teachers can  use Google Forms to make surveys , quizzes, or event registration sheets. The form is web-based and can be shared with respondents by sending a link, emailing a message, or embedding it into a web page or blog post. Data gathered using the form is typically stored in a spreadsheet. Although there are other online survey apps, Google Forms is an excellent free option. I have prepared for my students “GRAVITATION” chapter  where I got instant responses and grading too, its a really good application, where you can know how much students has understood. I t provides the best-kept secret of Google Forms and explains how to set up auto-grading quizzes, digital escape rooms, online learning stations, and MORE! 1)  C reate surv...
