What else can I help you with?
What characteristics do all lipids have in common?
One characteristic of all lipids is that they are all hydrophobic.
What characteristics of lipids enables macromolecules to repel water?
hydrophobic
What is the solubility of lipids in chloroform?
Lipids are highly soluble in chloroform due to its non-polar nature, which matches the non-polar characteristics of lipids. This solubility property makes chloroform a common solvent for extracting lipids in laboratory experiments.
Does hamburger juice have lipids?
Yes, hamburger juice has lipids. A way to test for lipids is to use Sudan IV and when exposed to Sudan IV it separates (due to its non polar characteristics) and there is a concentrate in the upper half of the test tube (the part that contains the lipids) which then gets dyed red. This equals positive lipids.
The plasma membrane has some interesting characteristics. What are they?
it is gel-like composed of proteins, lipids and carbs.
What do lipids desolve in?
Lipids dissolve in non-polar solvents such as organic solvents, including chloroform, ether, and benzene. These solvents have similar non-polar characteristics as lipids, allowing them to interact and dissolve effectively. Lipids are generally not soluble in water due to their non-polar nature.
What nmacromolecule is not organized in repeating units of monomers?
That are the lipids. They have fatty acids and glucerols
Are steroids lipids?
No, steroids belong to lipids, but not all lipids are steroids: eg. natural fats or oils are triglyceridic lipids, not steroidic lipids
Which macromolecule provides insulation and helps animal conserve heat?
That is the lipids. It is a good insulator.
Which ckass of macromolecules is not organized in repeating units of monomers?
The most common example is lipids.
What are two groups of lipid?
There are four main groups of lipids. They are fatty acids, glycerides, non glycerides, and complex lipids. The groups are determined based on storage of energy, structure of cell membranes, and signal of chemical biological activities.
What two characteristics tend to make lipids more soluble?
Lipids that are more soluble tend to have shorter hydrocarbon chains and higher degrees of unsaturation, as these features increase their interaction with polar solvents like water. Additionally, lipids with functional groups like ester or carboxyl are more soluble due to their ability to form hydrogen bonds with the solvent.
