Cells are capable of synthesizing new proteins, which are essential for the modulation and maintenance of cellular activities. This process involves the formation of new protein molecules from amino acid building blocks based on information encoded in DNA/RNA.
Virtual building blocks are used in drug discovery for drug design and virtual screening, addressing the desire to have controllable molecular morphologies that interact with biological targets. [8] Of special interest for this purpose are the building blocks common to known biologically active compounds, in particular, known drugs, [ 9 ] or ...
Lipids (oleaginous) are chiefly fatty acid esters, and are the basic building blocks of biological membranes. Another biological role is energy storage (e.g., triglycerides). Most lipids consist of a polar or hydrophilic head (typically glycerol) and one to three non polar or hydrophobic fatty acid tails, and therefore they are amphiphilic.
The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, appeared in both ancient Greece and ancient India. [6] Early philosophers who proposed the particulate theory of matter include the ancient Indian philosopher Kanada (c. 6th–century BCE or after), [ 7 ] pre-Socratic Greek philosopher ...
The division into blocks is justified by their distinctive nature: s is characterized, except in H and He, by highly electropositive metals; p by a range of very distinctive metals and non-metals, many of them essential to life; d by metals with multiple oxidation states; f by metals so similar that their separation is problematic.

Glycine is also an inhibitory neurotransmitter [9] – interference with its release within the spinal cord (such as during a Clostridium tetani infection) can cause spastic paralysis due to uninhibited muscle contraction. [10] It is the only achiral proteinogenic amino acid. [11]
Launched in 2015, the Allen Cell Types Database is a new tool to help scientists understand the building blocks of the brain and a major step toward creating a comprehensive map of the brain. The database will help create a common language for researchers around the world to use in observing, measuring and ultimately sorting cells into types ...
