A molecule is made up of two or more atoms that have bonded together, and it is the basic unit of any chemical compound. Given the broad nature of that definition, it is no surprise that molecules can come in all shapes and sizes, and some molecules are even made up of other ...
Atoms and molecules are so small in size that it is neither possible to count them individually nor possible to determine their mass. These are counted collectively in terms of Avogadro's number. The mass of Avogadro's number of atoms and molecules is known as gram atomic mass and gram mole...

say, common salt. To contrast the difference, the molecular weight of common salt is only 58.5, while that of a polymer can be as high as several hundred thousand thousands. These big molecules or 'macro-molecules' are made up of much smaller molecules. The small ...
Molecules Definition: Lesson for Kids from Chapter 2 / Lesson 27 45K Explore the tiny world of molecules and how they form every object in the world. Discover the relationship between atoms and molecules, how molecules are formed, and what determines the size and shape of molecules. Related...
The dataset used to generate all of the live cell figures is in Supplementary Data 3. N for each violin plot is in Supplementary Data 4. Source data Full size image To obtain additional information about the three-dimensional structure of the ensemble, we performed SEC coupled with SAXS (SEC...
IG molecules contain 2 sulfur atoms in their backbone, while AG molecules contain 3 sulfur atoms in their backbone. Frerigmann & Gigolashvili, 2014 studied the role of R2R3-MYBs under sulfur deficiency. Previous studies had identified that sulfur assimilation pathway genes are up-regulated under...
Caloric restriction is known to retard ageing and delay functional decline as well as the onset of disease in most organisms. Studies have implicated the sirtuins (SIRT1–SIRT7) as mediators of key effects of caloric restriction during ageing. Two unrelated molecules that have been shown to ...
How do the physical properties of polysaccharides, such as overall size, shape, branching, and composition, relate to their biological functions? What type of molecules have subunits called monosaccharides? Explain the bonds that form between proteins, amino acids, and carbohydrates. ...
What happens to the intermolecular force of attraction as the intermolecular space between molecules decreases? View Solution One of the assumptions of kinetic theory of gases states that "there is no force of attraction between the molecules of a gas". How far is this statement correct ? Is it...
