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

are some man-made materials which are commonly used. In this lesson‚ you will learn about the ways in which various materials are used in making common household items‚ in construction of houses and other buildings. You will learn about different polymers and their uses in our daily life. In addition‚ you will learn about the various medicines that help to cure different diseases and keep us healthy. OBJECTIVES After completing this lesson‚ you will be able to: • differentiate between natural and

The high cost of mAbs also prevents it from being a more common therapeutic method for treating maladies. These costs can be attributed to the multiple large doses that must be administered intravenously at regular intervals in order to maintain systemic volumes of distribution. Therefore‚ it is beneficial to explore an alternative method of delivery that can sustain delivery of mAbs in its therapeutic window for long periods of time. Oral antibody dosing shows almost zero bioavailability. Intravenous

and hydrogen‚ silicon and oxygen form numerous compounds. They are commonly known as silicates An Example - Beach sand is a good example for a mixture of silicates. Polymer - A large molecule made up of chains or rings of linked monomer units. Polymers usually have high melting and boiling points. An example - Examples of Polymer would be PVC (poly vinyl chloride)‚ polystyrene‚ and cellulose.

Organic Chemistry/Biochemistry 1: Compounds Important to Life • Biologists classify compounds into organic compounds and inorganic compounds. Organic Compound: a compound that is derived from living things and contains carbon Inorganic Compound: a compound generally derived nonliving things • Water Water is an inorganic molecule with unique properties that make it one of the most important compounds for living things. In the water molecule (H2O)‚ the hydrogen and oxygen atoms bond

through chemical bonds. Glucose‚ maltose‚ and glycogen are three carbohydrates that are similar‚ but structurally different. Carbohydrates have the general molecular formula CH2O. Starch and cellulose are the two most common carbohydrates. Both are polymers (hence "polysaccharides"); that is‚ each is built from repeating units‚ monomers‚ much as a chain is built from its links. The monomers of both starch and cellulose are the same: units of the sugar glucose. Carbohydrates are one of the four major

Structure and Function of Large Biological Molecules In Chapter 5‚ the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers‚ and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure‚ because this is central to understanding subsequent chapters on metabolism‚ molecular biology‚ and molecular

or in society are commonly encountered materials‚ for example‚ wood (timber)‚ concrete‚ brick‚ steel‚ plastic‚ glass‚ rubber‚ aluminums‚ copper‚ paper and ceramics. Generally‚ materials are classified into three types of groups; mainly metals‚ polymers and last but not least ceramics. Each and every type of the aforementioned group has their very own specialties‚ properties‚ structures and other characteristics. They all play an important role when it comes to selecting materials for the creation
