Macromolecules
Macromolecules are large molecules made up of smaller molecules joined together. The four main groups are proteins, lipids, carbohydrates and nucleic acids. They are essentially for proper cellular functioning.
755 Questions
How does basic structure of a steroid differ from other macromolecules such as carbohydrates?
a steroids has one ring with five carbons and three rings with six carbons and for carbohydrates: Monosaccharide has only one and a disaccharide has two etc..
Are proteins the most diverse class of macromolecules?
Yes, protiens perform many functions; this diversity of function is made possible by the diversity of protein structures.
If all fats are lipids why aren't all lipids fats?
While all fats are lipids, not all lipids are fats. Lipids encompass a wider category that includes fats, as well as molecules like phospholipids, steroids, and waxes. Fats specifically refer to lipids that are solid at room temperature and primarily function as energy storage molecules in organisms.
How many polymers do proteins have?
Proteins, also known as polypeptides, are polymers of individual amino acids (peptides). The number of amino acids in the protein chain varies widely.
There are dipeptides (2 amino acids), oligopeptides (with a small number of amino acids beyond 2), and full-scale polypeptides (which typically contain many amino acids).

There is no Ripjaws Code for DNA Lab. I wish there was though.
Which macromolecules surrounds and protect internal organs?
Plasma membrane protects cellular structures. They are made up of lipids
Why aren't amino acids considered a nutrient macromolecules?
If you have a(n) amino acid as a nutrient macromolecules, then everything that has it would be destroyed or killed, including fruits and animals, even people.
How does each of the four macromolecules of life function in living organisms?
carbohydrates and lipids are required as they are energy-giving substances, proteins are required as they are body-building substances, and nucleic acids are required as they store herditary information.
What kind of macromolecule is DNA polymerase?
DNA polymerase is an enzyme that helps catalyze the polymerization of DNA bases (deoxyribonucleotides) into a DNA strand.
Macromolecules are formed through a process called polymerization, where monomers are linked together via covalent bonds. This reaction often involves a dehydration synthesis (or condensation) reaction, in which water is removed as the monomers join together. For example, in the formation of proteins, amino acids are linked through peptide bonds, while carbohydrates are formed from monosaccharides linked by glycosidic bonds. This process results in the creation of large polymers such as proteins, nucleic acids, and polysaccharides.
The structure of carbon, with its four valence electrons, allows it to form stable covalent bonds with various elements, enabling it to create complex and diverse macromolecules. Carbon can bond with itself to form chains, branches, and rings, resulting in a wide variety of shapes such as linear, cyclic, and branched structures. These diverse configurations contribute to the unique properties and functions of macromolecules like carbohydrates, lipids, proteins, and nucleic acids, allowing them to perform specialized roles in biological systems. This versatility in bonding and structure is fundamental to the complexity of life.
How does the structures of fatty acids compare to the basic units found in other macromolecules?
Fatty acids consist of long hydrocarbon chains with a carboxyl group at one end, making them distinct from the basic units of other macromolecules. For instance, carbohydrates are composed of monosaccharides, which contain hydroxyl groups and a carbonyl group, while proteins are made up of amino acids, characterized by an amino group, a carboxyl group, and a unique side chain. Nucleic acids, on the other hand, consist of nucleotides, which include a nitrogenous base, a five-carbon sugar, and a phosphate group. Overall, the structural diversity of fatty acids reflects their unique roles in energy storage and membrane formation compared to the building blocks of carbohydrates, proteins, and nucleic acids.
Fatty acids consist of long hydrocarbon chains with a carboxyl group at one end, which distinguishes them from the basic units of other macromolecules like carbohydrates, proteins, and nucleic acids. For example, while fatty acids are primarily hydrophobic and serve as energy storage and structural components in membranes, carbohydrates are made of sugar units (monosaccharides) that are hydrophilic and primarily function as energy sources. This structural difference underlies their distinct roles in biological systems.
