Yes, macromolecules are large molecules that are formed by the joining of smaller units. Lipids fit that description, but they aren’t polymers because they are made up of smaller units of different kinds (like glycerol and fatty acids) rather than monomers that repeat themselves.
Why are proteins known as polymers?
Proteins are the macromolecules which are made from the amino acids when joined together by peptide bonds. Amino acids are polymers which are used to build tissues and other components of living organisms. Thus, they are called biological polymers.
What is the difference between lipids and proteins?
Proteins and lipids are examples of nutrients, molecules essential for growth and development of life. The difference is that lipids contain fatty acids and glycerol, while proteins contain amino acids, which have nitrogen.
Do proteins have Polymers?
Proteins are polymers of amino acids.
What are polymers of proteins called?
Proteins – polymers are known as polypeptides; monomers are amino acids. Nucleic Acids – polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group.
What exactly is a polymer?
Polymers are large molecules made up of long chains or networks of smaller molecules called monomers. Natural polymers include silk, hair, proteins and DNA, while synthetic (man-made) polymers include polyethylene, polypropylene and polyester.
What is polymerization example?
A polymer is a large single chain-like molecule in which the repeating units derived from small molecules called monomers are bound together. The process by which monomers are transformed into a polymer is called polymerisation. For example ethylene polymerizes to form polyethylene.
Why is cotton Fibre a polymer?
Cotton, like rayon and wood pulp fibers, is made of cellulose. The degree of polymerization is the number of repeating units that are linked together to form a molecule of cellulose. Crystallinity indicates that the fiber’s cellulose molecules are closely packed and parallel to one another.
