MacroMolecules, Genes, and Computers
MacroMolecules, Genes, and Computers International Symposium and Workshop: Chapter Three (MGC3) was held August 17-22, 1993, in Waterville Valley, New Hampshire.
macromolecules Large molecules made up of many small organic molecules that are often referred to as monomers; e.g., carbohydrates, lipids, proteins, and nucleic acids. Macromolecules are polymers of monomers.
Macromolecules and Monomers
Many of the common large biological molecules (macromolecules) are synthesized from simpler building blocks (monomers). Each of the types of molecules listed in the table are discussed below.
[edit] Macromolecules
Compounds that make up organisms may be divided into macromolecules and other, smaller molecules. The four groups of macromolecule are nucleic acids, proteins, carbohydrates and lipids.
Macromolecules are constructed by covalently bonding monomers by condensation reactions where water is removed from functional groups on the monomers. Cellular enzymes carry out condensation (and the reversal of the reaction, hydrolysis of polymers).
inhaled macromolecules (e.g., proteins on cat hairs that can trigger an attack of asthma in susceptible people)
ingested macromolecules (e.g., shellfish proteins that trigger an allergic response in susceptible people) ...

In the late endocytic pathway, it has been proposed that endocytosed macromolecules are delivered to a proteolytic environment by 'kiss-and-run' events or direct fusion between late endosomes and lysosomes.
Several different varieties of macromolecules may be digested by lysosomes and arrive at the organelles by disparate pathways.
So it has to assemble a whole bunch of macromolecules at that spot. And then it has to become ready, and then it has to wait for the calcium to come in, and then it can fuse.
The middle-sized molecules are organic molecules and most (the amino acids, nucleotides, sugars (monosaccharides) and fatty acids) are subunits of the macromolecules. However, some are not.
Used to make polyacrylamide gels for separation of macromolecules by electrophoresis.
It is actually a stack of membrane-bound vesicles that are important in packaging macromolecules for transport elsewhere in the cell. The stack of larger vesicles is surrounded by numerous smaller vesicles containing those packaged macromolecules.
Nucleic acid is an important class of macromolecules found in all cells and viruses. The functions of nucleic acids have to do with the storage and expression of genetic information.
Problem 7: Weak forces involved in interactions between macromolecules
Two macromolecules, such as proteins, can adhere tightly and specifically to each other.
This model of DNA appears courtesy of the Image Library of Biological Macromolecules based in Jena, Germany, which maintains a large archive of spectacular computer graphics of DNA, RNA, and proteins.
Important in fatty acid biosynthesis and catabolism and has found widespread use as a covalent label for macromolecules which may then be detected by high affinity binding of labelled avidin or streptavidin. Essential growth factor for many cells.
(en-doh-sy-toh-sis) [Gk. endon, within + kytos, vessel]
The cellular uptake of macromolecules and particulate substances by localized regions of the plasma membrane that surround the substance and pinch off to form an intracellular vesicle.
Enzymes Biological macromolecules that act as catalysts for biochemical reactions; although almost all are composed of protein, catalytically active RNA molecules have been recently discovered.
recognition surface The three-dimensional structure of a biological membrane surface that gives specificity due to macromolecules of various sizes and shapes that extend above the lipid bilayer.
A second meaning refers to cloning DNA, or the act of creating copies of an individual gene, for expression in a foreign host, which leads to generation of exact replica macromolecules (e.g. DNA, RNA, proteins).
4. How do Buffers Work?
Structural biology - a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules
Virology - the study of viruses and some other virus-like agents ...
- Large, complex molecules, such as proteins, nucleic acids, lipids and carbohydrates, that are produced only by living organisms. Biological molecules are often referred to as macromolecules or biopolymers.
Bioprocessing ...
nuclear membrane - similar in structure to the cell membrane, this structure separates the cytoplasm from the nucleus; contains large open pores for transfer of the macromolecules like RNA.
biological samples are directly imaged in the transmission electron microscope under low-dose conditions and at low temperature (at least -170 °C). The sample can be either a frozen layer of suspension that contains many isolated macromolecules for ...
