Why the basic structure of a cell membrane (bi-layer) is proteins and lipids? What type of bonds do lipids have? What is the effect of cholesterol in a membrane? The characteristic that all lipids have in common is that? What type of lipid is estrogen?
Fatty acids that have no carbon-carbon double bonds are saturated. These saturated fats are commonly found in animals and are usually solids. If one or more double bond is present, the fat is unsaturated. If only one double bond is present, the molecule is monounsaturated. The presence of t...
Lipids, like carbohydrates, contain "organic" atoms and "organic" bonds, but have fewer ___ and therefore, are mostly insoluble in water. a. covalent bonds b. non-polar covalent bonds c. soft ionic bonds d. polar covalent bonds e. molar covalent Which type of organic molecule ser...
All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportion of oxygen atoms. Although the st...
Fats and oils aren't just lipids, they are also two different substances with individual existence. But, how to determine what is fat and what is oil? It's indeed a difficult task. But, what if you have a thorough understanding of the difference between fats and oils based on characterist...
However, there are different levels of covalent bonding. Carbon can form nonpolar covalent (pure covalent) bonds when it bonds to itself, as in graphene and diamond. Carbon forms polar covalent bonds with elements that have a slightly different electronegativity. The carbon-oxygen bond is a polar...
The absence of double bonds decreases fluidity, making the membrane very strong and stacked tightly. Unsaturated fatty acids have at least one double bond, creating a "kink" in the chain.The double bond increases fluidity. What are the three classes of glycoproteins?
through a liquid medium. Their strong molecular bonds make lipids convenient for long-term energy storage. Lipid molecules are given their insolubility because they are formed with ester bonds: they are compounds formed from an alcohol and acid by the removal of a hydrogen atom in a water ...
Which types of lipids have esters (or ester bonds) as part of their structure? (Select all that apply.) a) Waxes b) Steroids c) Triglycerides d) Phospholipids e) Fatty acids f) Fat-soluble vitamins Which of these would NOT ...
Why do hydrogen ions have to bond with hydroxide ions? Can't they bond with something else with the same valence electron need? Why are molecules with double bonds stronger than those with single bonds? Are triple bonds even stronger than double bonds?
