Why are lipids unique when compared to the other macromolecule groups? Why are lipids good energy storage molecules? How do lipids go through the cell membrane? What makes lipids different from other organic compounds? Describe how carbohydrates, proteins, and fats are used to meet the energy nee...
Several dozen lipids participate in intra- and intercellular signalling processes. In most instances, the levels of signalling molecules are exceedingly low compared with the complement of structural lipids that is present in membranes. Lipids adopt defined phases depending on their molecular structure and...
What are the similarities between the chemical structure and composition of proteins, carbohydrates, and lipids? How is a protein different from a carbohyrate? a. The monomers that make up a protein are called amino acids whereas the monomers that make up a complex carbohydrate are called simple...
Molecules are constantly vibrating, and these vibrations change when the molecules absorb IR light. The changes in vibration include the bending and stretching of various bonds. Each type of bond within a molecule absorbs IR at different wavelengths. So, to identify ethanol in a sample, you have...
biomolecule, also called biological molecule, any of numerous substances that are producedby cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and ...
How do lipids go through the cell membrane? How would you design a cell membrane that would allow you to move more material through the membrane faster without taking more space? How do hydrophilic molecules cross cell membranes? How does the concept of osmosis interact with the body's cells...
Biosurfactants are amphiphilic substances produced by microbial metabolism that contain both hydrophobic and hydrophilic groups, mainly composed of proteins, sugars, and lipids87. The structure of BS can be identified using various techniques such as thin layer chromatography, Fourier Transform Infrared Spec...
Within each class of compounds, the variations around the basic chemical skeleton essentially concern the degrees of oxidation, hydroxylation, methylation, glycosylation and the possible connections to other molecules (primary metabolites such as carbohydrates, lipids, proteins, or phenolic secondary ...
How do lipids differ from carbohydrates? Why are the brain and red blood cells insulin independent? Why is the pancreas important? Why is glucose called a reducing sugar? Is insulin a hormone or neurotransmitter? Explain the homeostatic mechanism, regarding the regulation of glucose homeostasis, giv...
How are lipids diffused into cells? How do saturated triglycerides compare to unsaturated triglycerides? How does the body recover from vigorous exercise? How does homeostasis regulate heart rate? How do the blood, cardiovascular, muscular, and respiratory systems all contribute to respiration?
