Macromolecules made up of many repeating subunits are called ____________?
polymers
Lipids are called macromolecules as they cannot be true polymers. Why?
Good question, but I get the impression that it would be better to phrase it this way: lipids are called macromolecules even though they cannot be true polymers. Why is that? Unlike carbohydrates (sugars), proteins (amino acids) and nucleic acids (nucleotides), lipids are not made out of multiple repetitive subunits joined in long, polymeric chains, and their amphiphile nature is strongly expressed through the observed structural differences between segments (tail, head). Clearly, other criteria are applied in the case of lipids. It is sensible to take up molecular weight as primary candidate. Another criterion is their sheer biological significance for the cells and thus organisms.
Can a cell be called a macromolecule?
No, cells possess macromolecules such carbohydrates, vitamins, proteins so on and so forth.When you call something as a macromolecule, it means that, it is a large (macro=large) molecule made up of many smaller subunits. One such example for macromolecules are proteins made up of multiple subunits called amino acids. You cannot call a cell a macromolecule because it's a composite made up of multiple structures n organelles that produce/utilise/made up of macromolecules.
Proteins are large macromolecules composed of thousands of subunits. The structure of the protein depends on?
Answer --> C. Amino Acids Amino acids are join together to create a chain of "peptide bonds". As this chain grows, it bends and twists due to intermolecular forces until it is stable. This new structure is the actually proteins. *Note: Many times, proteins are composed of multiple amino acid chains like the one described above.
Describe the four types of macromolecules?
Carbohydrates are compounds made up of carbon, hydrogen, and oxygen atoms. contains monosaccharides (single sugar molecules). use it as main source or energy Lipids are made up mostly from carbon and hydrogen atoms. some lipids are formed when a glycerol molecule combines with fatty acids. Nucleic acids contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers assembled from individual monomers called nucleotides. they store and transmit hereditary information. the 2 kinds are RNA and DNA Proteins contain nitrogen as well as carbon, hydrogen, and oxygen. they are polymers of molecules called amino acids.Some proteins control the rate of reactions and regulate cell proccesses . some are used to form bones and muscles. others transport substances into or out of cells or help fight disease
How do monomers combine to form macromolecules?
I'm supposed to be writing a lab report which contains some discussion questions which aren't in my textbook and which we haven't covered in class either. Google isn't helping me that much as I don't really know what I'm looking for: "Lipids, proteins, and carbohydrates are called macromolecules because they are made up of smaller units. What are each of these smaller units called? Write an equation of how they combine to form lipids, proteins and carbohydrates." I'm not even certain monomers are the smaller units of macromolecules. Thanks in advance!
What is the difference between a macromolecule and a polymer?
In my notes (from my highschool class) I have that: cells make most of their large molecules (macromolecules) by joining smaller organic molecules into long chains The smaller molecules are called monomers The large molecules made of many monomers linked together are called polymers I can't figure out how a polymer is different than a monomer. Thanks
What is the difference between macromolecule and polymer?
Macromolecules are molecules made of smaller subunits. Polymers are macromolecules made of repeating subunits.For example, a protein is both a macromolecule and a polymer since it is made of repeating units of amino acids. Theorically, there are no limits to how many amino acids there can be in a protein molecule. A tryglyceride is a macromolecule but not a polymer. Tryglycerides are made of a glycerol binded with three fatty acids. There are no repeating units. So tryclycerides are not polymers.—Gt. Yuhan Zhang (Proud A-level Biology student)
