  Digestion of carbohydrates begins in the mouth and continues through the stomach and the small intestine. There are basically three types of carbohydrates that are digested by the human body and they are sucrose which is found in the cane sugar or we can say the normal sugar we eat, second is lactose or the carbohydrate part present in milk and dairy products. The third type of carbohydrate that we intake is a polysaccharide which is starch which we intake as grains. In layman terms carbohydrate is the part of diet such as sugar, dairy and grains. The former two are disaccharides and only starch is polysaccharide. After knowing what carbohydrates  we are intaking now should know how these are digested in our digestive system. Firstly, all the food we take weather be it carbs, fat or proteins they undergo hydrolysis(breakdown of a chemical compound due to water) and in case of carbohydrate it goes as follows. R”-R’ + H 2 O → R”OH + R’H Here hydrolysis is breakdown...

  INTRODUCTION Route of administering drugs in the body can be different, like a particular drug let’s take paracetamol, when we have fever it’s the most common drug that we take and when our situation worsens the doctor might inject it too. So what are different ways in which we can take drugs? Why are there so many different ways of taking drugs in our body and what does it signify? So, let’s take a look at the factors what governs the choice of the route of the drug i.e how a drug should be taken. 1.      1. Physical and chemical properties of the drug, weather the drug is solid liquid or gas. Its solubility in different body fluids, because we cannot take a drug which is a gas like NO by oral route, it will be absurd. 2.   2. Site of desired action is also taken into consideration because many drugs require a localised effect and other drugs require a specific site of action 3.   3. And we should also take into account that the drug we take...

  INTRODUCTION      Everybody in their lifetime has taken drugs not the illegal ones but the drugs that a doctor prescribes us when we fall ill. Maybe we sometimes self prescribe our drugs and end up having some OTC drugs. Many of the drugs we use have different natures like we can say they have different properties. So here we may learn about a few of them to get a view of the nature of some of the drugs that we might have taken. 1. Nature of drugs Drugs are basically substances that bring about a chemical reaction in our body be it beneficial or harmful. Now one might ask how these chemical reactions are triggered by a simple pill that we take. Well, it's by the chemicals that they contain ie. The chemical in the pill we take can be an agonist or an antagonist. Agonists are those chemicals which bind to the receptors in our body and activate the chemical pathway again which might have been disturbed. Antagonists do the opposite ie. They inhibit the che...
