Mechanism of Iron absorption

Learning resources, Lecture notes, Library, Minerals, Theory notes /

Iron absorption takes place largely in the proximal small intestine and is a carefully regulated process. In general, there is no regulation of the amounts of nutrients absorbed from the gastrointestinal tract. A notable exception is an iron, the reason that absorption must be carefully regulated is that the body does not possess a physiological

Q.1- Discuss in brief about the isomerism in monosaccharides.Answer- The sugar molecules having asymmetric carbon atoms exhibit isomerism. Asymmetric carbon atom- It is the carbon atom that is attached to four different groups. All monosaccharides except- Dihydroxyacetone, have asymmetric carbon atoms. Based on the presence of asymmetric carbon atoms the following types of isomerism of monosaccharides are

Glycosaminoglycans and proteoglycans – A quick revision

Animations, Chemistry of Carbohydrates, Learning resources, Library, Theory notes /

Introduction The most abundant heteropolysaccharides in the body. Highly negatively charged molecules, with extended conformation that imparts high viscosity to the solution. GAGs are located primarily on the surface of cells or in the extracellular matrix (ECM). Along with the high viscosity of GAGs comes low compressibility, which makes these molecules ideal for a lubricating
