What is AMBER chemistry?

Natural resins such as amber generally consist of mixtures of organic compounds, including alcohols, ketones, carboxylic acids, and most notably, unsaturated hydrocarbons known as terpenes and related terpenoid compounds.

What is AMBER algorithm?

“Amber” is the collective name for a suite of programs that allows users to carry out and analyze molecular dynamics simulations, particularly for proteins, nucleic acids and carbohydrates.

What is AMBER relax?

Orthopaedic relax grip amber handle – For Left Handed Use The ergonomic designed ‘relax grip’ shape, allows the thumb and forefinger to rest over the handle, while the palm is supported, providing a comfortable grip that helps to reduce hand strain during use.

Is AMBER a software?

Amber is a suite of biomolecular simulation programs. It began in the late 1970’s, and is maintained by an active development community; see our history page and our contributors page for more information.

What is amber made of?

Amber is formed from resin exuded from tree bark (figure 9), although it is also produced in the heartwood. Resin protects trees by blocking gaps in the bark. Once resin covers a gash or break caused by chewing insects, it hardens and forms a seal.

What is the chemical formula of amber?

C 10 H 16 O
Its basic ingredients are carbon (approximately 78%), oxygen (11%), hydrogen (10%). The following formula of amber as a mineral is usually given – C 10 H 16 O.

How amber is formed?

What is the meaning of amber in physics?

In Physics, amber is a petrified tree resin. According to Greeks, when an amber is rubbed against a rod along with a piece of cloth, the amber attracts the small piece of dust. A glass rod, a plastic rod, or a hard rubber when rubbed against a cloth, display amber effect which is commonly known as static electricity.

How is AMBER relevant in the field of electrostatics?

When friction is applied, amber becomes negatively charged and attracts lightweight particles such as pieces of straw, fluff, or dried leaves. Its ability to produce static electricity has fascinated observers from the earliest times.

What is AMBER Sander?

sander is the basic MD engine of Amber. pmemd is the high performance implementation of the MD engine that contains a subset of features of sander. pmemd can also be run with acceleration from graphics processing units (GPU).

Is amber a crystal?

Amber is a member of the organic gemstone family, just like Coral, Pearls and Jet. These gemstones do not have an organised crystal structure and so cannot be classified as a mineral. Each Amber gemstone is unique and likely mined from the Baltic region.

Is amber a rock or mineral?

Most gemstones are minerals, however, Amber is not a mineral. Why not? It’s because Amber is a hardened resin of specific species of ancient trees which has been fossilized over many years.

What are the properties of amber?

It has a melting-point range of 200 to 380°C, but it tends to burn rather than melt. Amber is amorphous in structure and, if broken, can produce a conchoidal, or shell-like, fracture. It is a poor conductor and thus feels warm to the touch in the cold, and cool in the heat.

Is amber a sap?

Amber is the fossilized resin from ancient forests. Amber is not produced from tree sap, but rather from plant resin. This aromatic resin can drip from and ooze down trees, as well as fill internal fissures, trapping debris such as seeds, leaves, feathers and insects.

Is amber a piezoelectric?

The Greek name for amber is electron as the ancient Greeks thought amber to be pieces of the sun, broken off and fallen into the ocean. Due to the piezoelectric property of amber – it will obtain a negative electric charge when rubbed – the quantum particle electron was named after amber.

Can amber be magnetic?

Its ability to produce static electricity has fascinated observers from the earliest times. Amber’s magnetic property gave rise to the word electricity: amber (Greek, elektron) was used in the earliest experiments on electricity.


CHARMM and AMBER are the force fields used in the computational simulation for the properties of dna, protein, etc. I’d like to know that, when to use CHARMM or AMBER force field. Also is it necessary to do MD Simulation via both of them.

What is molecular dynamics used for?

Molecular dynamics can be used to explore conformational space, and is often the method of choice for large molecules such as proteins. In molecular dynamics the energy surface is explored by solving Newton’s laws of motion for the system (see 4.25 Applications of Molecular Dynamics Simulations in Drug Design).

What mineral is amber?

Amber is not a mineral, since it has an organic origin and has no internal arrangement of atoms. The composition of amber may vary greatly depending on the botanical source, though all specimens are believed to be fossilized tree resin.

What properties does amber have?
