Covalent bond

as a source of food of many higher organisms in the food chain. It is one of the many biological molecules present in plants and needed by animals. Biological molecules are macromolecules composed of many monomers (polymer) connected through a covalent bond forming polysaccharides, proteins, and nucleic acids (Table 1). They have specific, characteristic three-dimensional shapes that depend on the structure, properties, and sequence of their monomers important for their biological functioning…

organisms, in the form of an organic compound, as well as in some non-living things, such as rocks and wood. These organic compounds, made up of carbon, make up cells which is why without them life would not be possible. The reason carbon can easily bond with so many different…

that ethanol has the ability to make hygrogen bonds. These are the weak, yet plentiful, bonds a hydrogen atom can make with a negative atom like oxygen or nitrogen. If you don't remember hygrogen bonds, please look them up. They are not ionic bonds nor covalent bonds, but rather weak attractive forces between hydrogen and a semi-negative charged oxygen or nitrogen. Hydrogen bonds are one of the major reasons we have life on earth. Hydrogen bonds give water its properties including how…

Gibson 1 Reagan Gibson Tripp Sanders Chemistry 1 May 2016 Introduction A Chemy Called Al is quite an interesting read. It is written by Wendy Isbell. It tells the story of a girl named Julie. The book begins talking about Julie and her electrical issues. It talks about her power being out but the TV still being on. It had to do with X-Ray Machines around the whole country. Well she goes to the land of Mathematics, she is afraid her friends are in danger- so she decides to go find them.…

very least. Proteins have Nitrogen as an added element, and DNA has Phosphate and Nitrogen. The base structure of each molecule has a carbon skeleton. This means that structures have Carbon as the base, in diagrams the carbon skeleton will have many bonds but you can recognize it because it will be in the middle of every molecule. Carbohydrates are the main fuel molecules for cellular work, and they provide raw…

bonded together to create larger molecules via dehydration. This involves the removal of a water molecule at the bonding site. The larger molecule can be broken down by the reverse process, hydrolysis. This occurs when water is added to break the covalent bonds created during dehydration. The monomer unit for carbohydrates is a monosaccharide or a simple…

crystalline phase of several components in a certain stoichiometric ratio, where different types of molecules that interact with hydrogen bonds or other non-covalent bonds [12]. The pyridine ring in their chemical structure LOR as shown in Fig. 1a allows the proton transfer with carboxylic acids to form a salt. Furthermore, N of the pyridine ring may also act as a hydrogen bond acceptor, allowing the formation of co-crystal when it binds to the hydroxyl group of carboxylic acids. Fumaric acid…

These atoms are bonded by covalent bonding. The geometry of water is a bent shape which accounts for many of its properties. The water molecule is polar, but the molecule itself is electrically neutral. One property of water is that its solid form is less dense than its liquid form…

Gilbert Lewis first introduced his theoretical dot structures in 1916. Today, these same dot structures are used to illustrate the chemical bonding nature of atoms. How did Lewis formulate these brilliantly simple representations of nature? The Lewis Dot Structures we know today actually derive their functionality from Lewis’ own model of the atom, the Theory of the Cubical Atom. This essay will explore the functionality of Lewis’ cubical atom and how this model led to the Lewis Dot Structures.…

It has long been studied that saturated fats increase cholesterol. Mono-unsaturated (one carbon double-double bond) and polyunsaturated (more than one carbon double-double bond) found primarily in vegetable oils, tend to lower cholesterol and therefore better for your health. Higher cholesterol elevates the chances of getting coronary heart disease. Back in the 1950’s, it was discovered that animal fats could be substituted with vegetable oils in the substance we know as margarine. This meant…
