A macromolecule is a very large molecule, such as protein, commonly created by polymerization of smaller subunits (monomers). They are typically composed of thousands or more atoms. The most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, carbohydrates and polyphenols) and large non-polymeric molecules (such as lipids and macrocycles). Synthetic macromolecules include common plastics and synthetic fibres as well as experimental materials such as carbon nanotubes.
Macromolecule
Polymer molecule
A molecule of high relative molecular mass, the structure of which essentially
comprises the multiple repetition of units derived, actually or conceptually, from
molecules of low relative molecular mass.
1. In many cases, especially for synthetic polymers, a molecule can be regarded
as having a high relative molecular mass if the addition or removal of one or a
few of the units has a negligible effect on the molecular properties. This statement
fails in the case of certain macromolecules for which the properties may be
critically dependent on fine details of the molecular structure.
2. If a part or the whole of the molecule fits into this definition, it may be described
as either macromolecular or polymeric, or by polymer used adjectivally.
Hank talks about the molecules that make up every living thing - carbohydrates, lipids, and proteins - and how we find them in our environment and in the food that we eat.

Updated video on biomolecules (macromolecules): carbohydrates, lipids, proteins, and nucleic acids by the Amoeba Sisters including examples, functions, monomers, and structures! Handout available on www.AmoebaSisters.com Video Note: Video mentions that many do not consider lipids to have true monomers. This is due to the fact that their building blocks are made of two different substances (glycerol and fatty acids) that attach to each other--rather than attaching as one type of monomer to another. Also, due the the diversity of lipids, there are lipids that have a very different structure than discussed in this video. The Amoeba Sisters Channel features two sisters on a mission to demystify science with humor and relevance by creating free science videos. Since one of us is a biology te...
What are macromolecules? Cells of the body have four main macromolecules that help keep the cell alive and functioning properly. The four macromolecules are carbohydrates,lipids,proteins, and nucleic acids. A macromolecule is a large molecule formed when elements and molecules combine together. Elements like carbon,hydrogen, and oxygen join together to make up macromolecules. Each macromolecule is unique and made up of different smaller molecules. Look at the macromolecule DNA compared to a water molecule. Carbohydrates are composed of three elements, carbon,hydrogen, and oxygen. Carbohydrates store energy and provide structural support. Sugars and starches are carbohydrates. The cell wall of plants is composed of the carbohydrate cellulose Lipids are macromolecules composed of carbon,...
Paul Andersen describes the macromolecules that make up living organisms. He starts with a brief description of organic chemistry and the importance of functional groups. He also covers both dehydration and hydrolysis in polymerization. He finally covers the four major macromolecules: nucleic acids, proteins, lipids and carbohydrates.

Video lecture on the major macromolecules in biology.
Just something we did for extra credit in biology. Hopefully it can help you understand macromolecules better.(: LYRICS: [VERSE 1] I've never learned so much in 4 months. Just to study for mid terms, or at least try to. And I'm not too proud of some grades, but I've learned so much, all thanks to Mrs. Hayes. [HOOK] So lets talk about macromolecules, there are only four types: carbs, protein, lipids and nucleic acids. We don't care, we're acing every one of our tests. [SECOND VERSE OF HOOK] And they're made up of: oxygen, hydrogen, nitrogen, and phosphorus carbon, which is what tells if its organic. In the end, they're what we're made of so they're our friends. [CHORUS] And they are made of monomers, (monomers) Different kinds for everyone. Amino acids for proteins, it's every bio s...

4 Types of Macromolecules Polymers vs Monomers Dehydration Synthesis Hydrolysis
In the incredibly dense yet invisible world of the cytoplasm in biological cells, complex interactions can be thought of as a playful dance between macromolecules, minerals, ions and proteins.These cytoplasmic playgrounds are reimagined using dynamic particle systems that play out and evolve differently each time, mimicking stochastic processes in nature. This video shows recorded snapshots taken from these computational outbursts. Sound was created using granular synthesis techniques.

Gaël McGill (http://bit.ly/pmgxqF) introduces key visualization methods used to study macromolecular dynamics, finishing with several stunning, narrative-driven visualizations created by tools such as BioBlender, ePMV, and Molecular Maya. He highlights the current lack of sharing of molecular meta-models as a key challenge impeding progress, and discusses the need to bring macromolecular dynamics into education. This talk was presented at VIZBI 2011, an international conference series on visualizing biological data (http://vizbi.org) funded by NIH & EMBO.

Delaware New Tech Academy investigates a murder mystery by solving for macromolecules in the victim's and suspect's stomach contents. A literature component is satisfied by reading "The Lovely Bones" by Alice Sebold.
Arthur Olson (http://mgl.scripps.edu) gives a very engaging demonstration of how molecular recognition and self-assembly can be explored using an innovative, hybrid user interface that combines 3D solid printing and his own augmented reality environment. He argues that a synthesis of both abstract & 3D visualization is needed to understand biological processes. He then presents impressive, cutting-edge methods for fast, integrated, and large-scale macromolecular visualization.

In this introduction to the BioBlender extension to the 3D graphics program Blender (version 2.5), Monica Zoppe presents the basic principles behind BioBlender's 3D rendering of biological macromolecules (protein, DNA, etc.) from protein data bank (PDB) files.
