The following are examples of the most common organic molecules in living things: Monosaccharide sugars. These are the monomers from which larger polymer molecules are constructed. Molecules like glucose and fructose are metabolically active molecules usually stored in an inactive‚ insoluble polysaccharide form. Glucose: C6H12O6 this is a hexose sugar (six carbons)

(amylose and amylopectin) formed from alpha-glucose. Amylose is formed when many alpha-glucose molecules condense together forming 1‚ 4 glycosdic bonds‚ so producing long unbranched chains. These chains take up a coiled or helical configuration as each monomer has a bulky side group which has to be accommodated. Amylose forms about 20% of starch. Amylopectin is branched and consist of alpha-glucose condensed together in two ways forming 1‚ 4 glycosidic bonds and 16 glycosidic bonds. The coiled chains of

Chapter Four DEFINITIONS nucleic acid – polymers specialized for the storage‚ transmission between generations‚ and use of genetic information. There are two types‚ DNA and RNA nucleotides – monomers that compose nucleic acid‚ consist of a pentose sugar‚ a phosphate group‚ and a nitrogen containing base. DNA - – a macromolecule that encodes hereditary information and passes if from generation to generation. RNA and the bonds that stabilize them Purine - one of two chemical forms

Jordan Wong Schiefer Acc Bio Block 6 11/15/12 Unit 4 Biochemistry relates to all things living because biochemistry makes up everything living. The atoms that make up the cells within our body are a part of biochemistry. There is carbon in every living thing and carbon based molecules are a part of biochemistry. Unit 4 describes the biochemistry in all living things. It explains the atomic structure and ions‚ properties of water and pH‚ organic molecules‚ chemical reactions and enzymes.

either split or bonded through dehydration synthesis or hydrolysis. Dehydration synthesis occurs when water is released‚ electrons become shared‚ covalently bonding two monomers together. Hydrolysis takes place when water is added to a polymer‚ energy is released and the covalent bonds break‚ turning the polymer into monomers. The ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrates. Carbohydrates can be divided up into three separate categories. Monosaccharides are simple sugars

CHAPTER 1 Coagulation Pathway and Physiology Jerry B. Lefkowitz‚ MD Introduction Our understanding of blood clotting is intimately tied to the history of civilization. With the advent of writing 5000 years ago‚ it could be argued that the first symbols used for blood‚ bleeding‚ or clotting represented the first published coagulation pathway. The ancient peoples of the world always held blood in utmost mystical esteem. Through the ages‚ this esteem has been transmitted to modern times in the

Chemical Bonding and Structure In his essay I will be discussing the scientific background and explanation of chemical bonding and structure‚ I will also be describing the method of injection molding and its benefits and limitations and how it is superior to the previous methods of making plastic. Finally I will also list the implication effect of plastic and its effect (economically and environmentally) A chemical bond is the result of a lure (attraction) between atoms or ions
