What else can I help you with?
Do lipids have a nitrogen base?
No. Lipids are composed of a "backbone" of glycerol and three carboxylic acid groups of varying length. Both glycerol and carboxylic acids contain only the elements carbon, hydrogen and oxygen.
What two macromolecules are used as the primary source of energy for cellular functions?
Carbohydrates and lipids are the two macromolecules used as the primary source of energy for cellular functions. Carbohydrates are broken down into glucose, which is the main source of energy for cells. Lipids can store and provide energy for longer periods of time compared to carbohydrates.
Explain what distinguishes lipids from other major classes of macromolecules?
Lipids are not soluble in water. improved..>> macromolecules have smaller subunits eg. protein-amino acid, carboyhdrate monosacharide, nucleic acid-nucleotide. unlike all the above examples lipids subunits are fatty acids which do not form covalent bonds with one another, rather they 'aggregrate' together.
Are lipids made of chains of amino acid?
No, that's proteins
What is the generalization of solubility of lipids?
Lipids are generally insoluble in water due to their hydrophobic nature, but they can be soluble in nonpolar solvents like ether or chloroform. Lipids can form micelles or bilayers in water to increase their solubility through hydrophobic interactions. The solubility of lipids can also depend on their structure and the specific interactions with the solvent molecules.
What class of macromolecules do phospholipids belong to?
The lipids are the only class of macromolecules that contain fatty acids, steroids, phospholipid, and more.
Which macromolecules have only atoms of c h and o?
The macromolecules that are composed primarily of C, H, and O are lipids and carbohydrates.
Cells membranes do not have what type of macromolecules?
Nucleic acids. The membrane contains mostly lipids. Other molecules acting as receptors contain both protein and carbohydrates. so the only macromolecule missing is nucleic acids.
What conclusion could you make if a positive test for any of the macromolecules occurred in the test tube containing only pure water?
If a positive test for any of the macromolecules occurred in a test tube containing only pure water, it would suggest contamination or an error in the experiment. Pure water should not contain macromolecules like carbohydrates, proteins, or lipids. This unexpected result indicates that either the reagents used in the testing process were contaminated or there was a mistake in sample handling. Further investigation would be needed to determine the source of the contamination or error.
Which pair of elements is found in only one of the four types of macromolecules?
Nitrogen and phosphorus are found in only one of the four types of macromolecules. Specifically, nitrogen is a key component of nucleic acids (like DNA and RNA) and proteins, while phosphorus is primarily associated with nucleic acids and ATP. Carbohydrates and lipids do not contain these elements. Thus, the unique presence of nitrogen and phosphorus in nucleic acids distinguishes them from the other macromolecule types.
Do lipids have a nitrogen base?
No. Lipids are composed of a "backbone" of glycerol and three carboxylic acid groups of varying length. Both glycerol and carboxylic acids contain only the elements carbon, hydrogen and oxygen.
Cell membranes are made of all macromolecules except?
Of the major biomolecules, lipids, carbohydrates, proteins and nucleic acids, only nucleic acids are not present in cell membranes. Lipids make up the bilayer; proteins craete pumps and channels; carbohydrates are part of glycoproteins but no RNA or DNA is present.
How are lipids like carbohydrates?
lipids contain energy just like carbohydrates,but lipids contain more energy Source: North Shore Community College Student Carbohydrates do contain energy but only for short periods of time, where as Lipids can contain energy for long periods of time even if this means that they are under-water.
The class mammalia contain the only animal that?
have mammary glands
Which of the following macromolecules are in butter protein carbohydrates lipids nucleic acids?
Whole butter, although it may appear to be a solid fat, is a combination of proteins, carbohydrates, and lipids. Clarified butter, which is used for frying at high temperatures, is butter without the water-soluble part and thus only a lipid.
Does egg white contain lipid?
Yes. Egg yolks contain fat in the form of lipids. I mean what percentage of moisture contain & what is the percentage of fat & emulsifier present in the egg
How much energy do lipids store as compared to carbohydrates?
lipids contain much more energy then carbohydrates. One gram of lipids create an average of 423 ATP or 0.47 mol ATP/gram. Glucose, with a molecular weight of 180.16, generates only 36 ATP, or 0.20 mol ATP/gram
