What are organic molecules?

Some articles on organic molecules, organic, molecules:

Abiogenesis - Other Models - Extraterrestrial Organic Molecules
... Based on computer model studies, the complex organic molecules necessary for life may have formed in the protoplanetary disk of dust grains surrounding the Sun ... observations suggests that the majority of organic compounds introduced on Earth by interstellar dust particles are considered principal agents in the ... Studies reported in 2008, based on 12C/13C isotopic ratios of organic compounds found in the Murchison meteorite, suggested that the RNA component uracil and ...
Physical Organic Chemistry
... Physical organic chemistry is the study of the interrelationships between structure and reactivity in organic molecules ... It can be seen as the study of organic chemistry using tools of physical chemistry such as chemical equilibrium, chemical kinetics, thermochemistry, and ... The term "physical organic chemistry" is commonly attributed to Louis Hammett, who used it as a title for a book in 1940 ...
Abiogenesis - Current Models - Origin of Organic Molecules
... There are two possible sources of organic molecules on the early Earth Terrestrial origins – organic synthesis driven by impact shocks or by other energy sources (such as ... carbonaceous chondrites) or gravitational attraction of organic molecules or primitive life-forms from space (see Panspermia) Recently, estimates of these sources suggest ...
Panspermia - Research - Extraterrestrial Life - Spaceborne Organic Molecules
... A 2008 analysis of 12C/13C isotopic ratios of organic compounds found in the Murchison meteorite indicates a non-terrestrial origin for these molecules rather than terrestrial contamination ... Biologically relevant molecules identified so far include uracil, an RNA nucleobase, and xanthine ... These results demonstrate that many organic compounds which are components of life on Earth were already present in the early solar system and may have played a key role in life's origin ...
Protein Skimmer - Function
... Protein skimming removes certain organic compounds, including proteins and amino acids, by using the polarity of the protein itself ... charge, water-borne proteins are either repelled or attracted by the air/water interface and these molecules can be described as hydrophobic (such as fats or oils) or hydrophilic (such as salt, sugar, ammonia, most ... However, some larger organic molecules can have both hydrophobic and hydrophilic portions ...

Famous quotes containing the word organic:

    And what if all of animated nature
    Be but organic Harps diversely framed,
    That tremble into thought, as o’er them sweeps
    Plastic and vast, one intellectual breeze,
    At once the Soul of each, and God of all?
    Samuel Taylor Coleridge (1772–1834)
