Define chemical group. chemical group synonyms, chemical group pronunciation, chemical group translation, English dictionary definition of chemical group. Noun 1. chemical group - two or more atoms bound together as a single unit and forming part of a mo
we use the term “category” to refer to any chemical class (at any level), each of which corresponds to a set of chemicals. These categories are arranged in a tree structure (Additional file1). The main relationship type connecting these different categories is the “is_a” relationship. ...
Calculating the thermodynamic properties of biochemical systems typically requires resource intensive, multi-step molecular simulations. Here, two deep neural network machine learning methods generate the thermodynamic state of dynamic water molecules in a protein environment solely from information on the stat...
Inference regarding chemical properties: in a defined group, data-poor chemicals are assumed to have similar properties or toxicity as the data-rich members of the same group. This is commonly known as read-across and is used in safety assessments of new chemicals to expedite the process and ...
The functional role of an ingredient is defined by the chemical’s properties and aids in determining its weight fraction in products. For example, Chevillotte et al. [27] described an exposure assessment method for cosmetics based on developing a “standard” or “virtual” composition of a ...
Although natural products and synthetic small molecules both serve important medicinal functions, their structures and chemical properties are relatively distinct. To expand the molecular diversity available for drug discovery, one strategy is to blend the effective attributes of synthetic and natural molecul...
Soil physical and chemical properties affect construction, plant growth, and functional development of habitat in created marshes (Callaway, 2001). Construction operations such as grading, installing drainage channels, and planting vegetation are generally less difficult on sandy soils than on fine-textur...
of biochemistry. The determination of the molecular structure of the organic substances present in living cells was necessary to the study of cellular mechanisms.Physical organic chemistryfocuses on the correlation of the physical and chemical properties of organic compounds with their structural features....
japonicae flos should be listed as independent species or considered the same, since they come from the same family and have similar history of efficacy, but they differ in plant morphology, medicinal properties, and chemical constituents. However, the descriptions of flavor, meridian tropism, ...
The choice of the polymer relied on the fact that it has the same chemical groups that are present in polylysine, i.e. -NH2,–COOH and –NH-C=O-. The effect of the deposition parameters on the properties of the thin films was studied and the surfaces with the best set of properties...
