The Fischer projection is a systematic way of drawing the skeletal formula of an acyclic monosaccharide so that the handedness of each chiral carbon is well specified.

The skeletal formula and substituent numbering scheme of the parent compound Dibenzo-1, 4-dioxin | dibenzo-p-dioxin

In skeletal formula the double bond is drawn as two parallel lines (=) between the two connected atoms ; typographically, the equals sign is used for this.

Another shorthand structural diagram is the skeletal formula ( also known as a bond-line formula or carbon skeleton diagram ).

In skeletal formula the triple bond is drawn as three parallel lines (≡) between the two connected atoms ; in typography, this is accomplished with the identity operator.

The skeletal formula of an organic compound is a shorthand representation of its molecular structure.

A skeletal formula shows the skeletal structure or skeleton of a molecule, which is composed of the skeletal atoms that make up the molecule.

For example, in the image below, the skeletal formula of hexane is shown.

The skeletal formula of hexane, with carbons number one and three labelled

Shown below for comparison are a ball-and-stick model of the actual three-dimensional structure of the ethanol molecule in the gas phase ( determined by microwave spectroscopy, left ), the Lewis structure ( centre ) and the skeletal formula ( right ).

Single bonds are most common and are represented by a single, solid line between two atoms in a skeletal formula.

* Skeletal formula, in chemistry, the skeletal structure or skeleton of a molecule

The skeletal formula of acetamidine ( acetimidamide )

The therapeutic index varies widely among substances: most forgiving among the opioid analgesics is remifentanyl, which offers a therapeutic index of 33, 000: 1 ; tetrahydrocannabinol, a sedative and analgesic of herbal origin ( genus Cannabis ), has a safe therapeutic index of 1000: 1, while diazepam, a benzodiazepine sedative-hypnotic and skeletal muscle relaxant has a less-forgiving index of 100: 1 and morphine, a sedative, antidepressant, and analgesic also of herbal origin ( genus Papaver ) has an index of 70: 1 ( which, however, is still considered very safe ).

In cases of narcolepsy, antidepressant compounds like clomipramine are used to manage symptoms of cataplexy, which usually manifests as sleep paralysis ( the inability to move skeletal muscles upon waking from REM sleep ).

A muscle relaxant is a drug which affects skeletal muscle function and decreases the muscle tone.

Gaining the weight, he said, was tougher than dieting himself into skeletal shape for his role as drug addict Harry Goldfarb in Requiem for a Dream.

It is a hypnotic drug used in the treatment of moderate to severe insomnia which has sedative and motor impairing properties, as well as anxiolytic, amnestic, anticonvulsant, and skeletal muscle relaxant properties.

Devlet, the author of " Rock Art and the Material Culture of Siberian and Central Asian Shamanism " highlights, “ Another interpretation of these skeletal costume elements explains them as representations of a shaman brought back to life after the dismemberment that occurs during the initiation process: the depicted bones thus refer to the wearer ’ s own skeleton ” ( 43 ).

Genetics, training, age, and skeletal soundness are all factors that contribute to a horse ’ s performance.

A horse ’ s skeletal system adapts to the exercise they are receiving.

To this day the church ’ s altar houses the skeletal remains of Sint Jeroen.

A little more than thirty years later, in August 1964, paleontologist John Ostrom led an expedition from Yale University ’ s Peabody Museum which discovered more skeletal material near Bridger.

Ostrom ’ s skeletal reconstruction of Deinonychus included a very unusual pelvic bone – a pubis which was trapezoidal and flat, unlike that of other theropods, but which was the same length as the ischium and which was found right next to it.

It allows for efficient animation of skeletal chains, such as a character ’ s spine or tail, and includes easy-to-use twist and roll controls.

The skeletal remains of the Nazis are found as well, including Elsa ’ s grandfather, who had apparently been murdered ( Jackie finds a knife in his back ).

The two most advanced 19th century classifications both used complex skeletal characters ; Milne Edwards and Haime ’ s 1857 classification was based on macroscopic skeletal characters, while Ogilvie ’ s 1897 scheme was developed using observations of skeletal microstructures, with particular attention to the structure and pattern of the septal trabeculae.

After creating an early body of work made up of closed form wooden objects, heavily-lacquered by hand, in the mid-1960s he “ decided to remove the skin altogether and reveal the structure .” This skeletal form, the radically simplified open cube, became a basic building block of the artist ’ s three-dimensional work.

The mesoderm aids in the production of cardiac muscle, skeletal muscle, smooth muscle, tissues within the kidney s, and red blood cell s.

The mesoderm aids in the production of cardiac muscle, skeletal muscle, smooth muscle, tissues within the kidney s, and red blood cell s. The ectoderm produces tissues within the Epidermis ( skin ) | epidermis and aids in the formation of neuron s within the brain, and melanocytes.

The undersized development of one side of a person ’ s face, demonstrates the influence of skeletal development upon the position of the external ear on the head, as caused by the deficient morphologic development of the temporal bone, and by the medial positioning of the temporomandibular joint, the synovial joint between the temporal bone and the mandible ( upper jaw ).

The article, titled " Concentration Camp for Dogs ," featured pictures of skeletal dogs and described the neglectful conditions that the investigative journalists and Maryland State Police found at a Maryland dog dealer ’ s farm.

Shells and skeletal remains of marine animals deposited on the shallow sands of what is now the Limestone Coast, and under the ocean ’ s weight these remains fused together to eventually form a layer of soft limestone.
