glucose and fructose. It is a C-4 epimer of glucose. Galactan is a polymer of the sugar galactose found in hemicellulose. Lactose- is a disaccharide sugar derived from galactose and glucose that is found in milk. Maltose- is a disaccharide formed from two units of glucose joined with an α bond‚ formed from a condensation reaction. The isomer isomaltose has two glucose molecules linked through an α bond. Amylose- Amylose is a spiral polymer made up of D-glucose units. This polysaccharide is one of the

What do these things have in common: a yo-yo‚ a kayak‚ a fleece pullover‚ and your school lunch tray? They can all be made from recycled plastic bottles or containers. In fact‚ the bottle you recycle in your own town can end up being spun into a pair of mittens worn by a child who lives in Japan. The plastic containers you recycle can take quite a journey once they leave your house. Of course‚ they can also wind up being put to the same use as before. We’re going to explore some unique paths you

In addition‚ to evaluate the effect of water washing process on the quality of fried and fried – treated sunflower oil. The metal patterns of sugar cane bagasse ash and Magnesol XL were

Due to the lack of durability of the adhesive in the past centuries‚ many people looked for stronger and fast-drying glues which led to the discovery of the synthetic glues we use nowadays. These modern adhesives dry quickly and form strong bonds. Superglues which are also known as instant glues set in seconds. They are the synthetic or commercial glues that we use today. Epoxy resins are also available wherein two ingredients are mixed together and then set in 10 to 30 minutes. Since glues

INTRODUCTION In this lab‚ we will be measuring the viscosity of samples of polyvinyl alcohols in order to determine the molecular mass of their components. Polyvinyl alcohol is an example of a synthetic polymer‚ which is a macromolecule. The general chemical structure of such compounds are well-characterized‚ although variation in characteristics such as molar mass‚ chain length‚ and extent of branching are not obvious from merely looking at their molecular formula. There is also the complication
