Why are metals more reactive in acids? Explain what the chemical process of hydrogenation does to fats. Why are amines described as derivatives of ammonia? Explain why most of the salts are soluble in water. Include molecular-level diagrams in the answer. Why are gadolinium salts used as MRI ...
Lipids are a class of macromolecules thatare nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats and oils are a stored form of energy and can include triglycerides. Fats and oils are usually made up of fatty acids and glycerol. Lipid...
Explain why triglycerides are nonpolar. Why are plants classified as producers? Why are plants autotrophs? Why do fatty acid come in chains of even-numbered hydrocarbons? Why do exoskeletons not decompose? Why is starch stored in plants?
Polar and Nonpolar Bonds The carbon to carbon and carbon to hydrogen bonds found in lipids are considered nonpolar. This means the electrons in the bond are shared relatively equally between the atoms. Conversely, the electrons in the bonds between hydrogen and oxygen in a water molecule are not...
forming physical barriers that keep droplets from coalescing. A type of surfactant (see Sidebar), emulsifiers contain both a hydrophilic (water-loving, or polar) head group and a hydrophobic (oil-loving, or nonpolar) tail. Therefore, emulsifiers are attracted to both polar and nonpolar compounds...
Acetone, though polar, is not so very polar that it will not dissolve nonpolar substances like fats and varnishes (it is often sold as nail-varnish remover). Other polar organic substances such as ethanol and ethyl acetate behave similarly. Only solvents of extreme polarity and hydrogen-bonding...
What is the difference between good fats and bad fats, and are good fats actually good for you or just not as bad? Why are hummingbirds so much more efficient than humans at metabolizing sugar? Why are fats nonpolar? Explain two health benefits of consuming high-fiber foods. Describe what...
Why are the molecules of hydrocarbons nonpolar? Why are saturated hydrocarbons generally less reactive than unsaturated hydrocarbons? Why are hydrocarbons extremely flammable? Why is it better to consume unsaturated fats than saturated fats? Why are lipids considered organic?
Non-polar Covalent Bond: A covalent bond where there is indiscernible electronegativity between two atoms. Polar Covalent Bonds: A covalent bond where there is discernible electronegativity between two atoms. Dipole: A condition where the positive and negative charges between atoms are separate from ea...
Why are intermolecular interactions minimized when temperature goes up or when molecule speed increases? Why are metamorphic rocks that are formed by contact metamorphism less dense? Why are the molecules of hydrocarbons nonpolar? Name three reasons why ice melts in an icebox.Explore...
