What are the four classes of macromolecules?
There are four classes of macromolecules that constitute all living matter: carbohydrates, lipids, proteins, and nucleic acids . While they have different structures and functions, they are all composed of long complex chains of molecules (polymers) made up of simpler, smaller subunits (monomers).
Why are lipids not considered macromolecules?
Because of their polymeric nature and their large (sometimes huge!) size, they are classified as macromolecules, big ( macro-) molecules made through the joining of smaller subunits. Lipids are not usually polymers and are smaller than the other three, so they are not considered macromolecules by some sources.
How do large molecules assemble?
Large biological molecules often assemble via dehydration synthesis reactions, in which one monomer forms a covalent bond to another monomer (or growing chain of monomers), releasing a water molecule in the process.

Why is it important to know about the presence of different types of macromolecules in our food?
It is important to know about the presence of different types of macromolecules in our food because it is important to maintain a healthy diet. Different types of macromolecules contribute to our bodily functions in different ways, and a diet consisting of balanced amounts of each macromolecule type helps our body function properly . Sugar and carbohydrates help provide us with the energy that our body uses. Lipids also play a role in the body’s energy production and use. Proteins are vital to our cellular functions, as they help transport molecules and replicate DNA. Because of this, we can see why keeping track of and adhering to a balanced diet can be beneficial to the body. In popular media, ‘eating healthy’ is sometimes portrayed as strict adherence to certain ‘nutritional philosophies’ in order to stay unnaturally thin, but in real life this is not the case. A real healthy diet consists of adequate and balanced intake of the macromolecules that the body needs.
What does Poom eat?
Poom loves to eat egg sushi whenever he could. He frequently have eggs with his meals. He also loves to eat fried chicken at school during milkbreak. Poom's diet is both healthy and unhealthy at the same time. Eventhough he is getting a good sources of protein from the egg sushi, there is also unwanted sucrose mixed in it. In the fried chicken, it's true that Poom gets a good amount of carbohydrate from the chicken and the starch which covers it, however, deep fried chicken also contain a huge amount of saturated fats, which are unhealthy for our body.
What are macromolecules?

How does the body make food into a bolus?
Before our bodies can make use of the food we eat, it must first break it into smaller particles for our bodies to harness the nutrients within. This starts in the mouth, where mastication (the act of chewing food) turns food into a bolus (a mass of chewed food just before swallowing).
What is a macromolecule?
A macromolecule is a very large molecule, usually consisting of repeated subunits called monomers, which cannot be reduced to simpler constituents without sacrificing the "building block" element. While there is no standard definition of how large a molecule must be to earn the "macro" prefix, they generally have, at a minimum, thousands of atoms. You have almost certainly seen this kind of construction in the non-natural world; for example, many kinds of wallpaper, while elaborate in design and physically expansive on the whole, consist of adjoining subunits that are often less than a square foot or so in size. Even more obviously, a chain can be regarded as a macromolecule in which the individual links are the "monomers."
What is the importance of macromolecules?
An important point about biological macromolecules is that, with the exception of lipids, their monomer units are polar, meaning that they have an electric charge that is not distributed symmetrically. Schematically, they have "heads" and "tails" with different physical and chemical properties.
Why are macromolecules polar?
Schematically, they have "heads" and "tails" with different physical and chemical properties. Because the monomers join head-to-tail to each other, macromolecules themselves are also polar. Also, all biomolecules have high amounts of the element carbon.
How many monosaccharides are in a polysaccharide?
Polysaccharides contain three or more monosaccharides. The longer these chains are, the more likely they are to have branches, that is, to not simply be a line of monosaccharides from end to end. Examples of polysaccharides include starch, glycogen, cellulose and chitin.
What are the four basic types of macromolecules?
These are often categorized into four basic types: carbohydrates (or polysaccharides), lipids, proteins and nucleic acids.
Why are proteins important?
But proteins are incredibly versatile, far more so than carbohydrates. In fact, without proteins, there would be no carbohydrates or lipids because the enzymes needed to synthesize (as well as digest) these molecules are themselves proteins.
How are bases different in DNA and RNA?
In both DNA and RNA, these bases can be one of four types; otherwise, all of the nucleotides of DNA are identical, as are those of RNA . DNA and RNA differ in three main ways. One is that in DNA, the pentose sugar is deoxyribose, and in RNA it is ribose. These sugars differ by exactly one oxygen atom.
