Phenyl

The name "phenyl" is taken from the French word phényl, which is derived from the Greek word phaino, which means "light," because the earliest phenyl compounds were created as a result of the building and refining of various gasses used for lighting. Phenyl Groups The phenyl group or phenyl ring is a cyclic group of atoms with the formula (C 6 H 5 ) in organic chemistry. another object or combination. which can serve as a working group. Six carbon atoms are grouped in a hexagonal planar ring in phenyl groups, five of which are bound to separate hydrogen atoms. The last carbon atom is bound in place. Inorganic chemicals, phenyl groups are common. Phenyl groups have a chemical odour and have the same bond length between carbon atoms in the ring, even though they are often expressed in different double-bonded bonds. The ‘phenyl group’ is usually similar to (C 6 H 5 ) and is defined by the letter Ph or, archaically, the symbol. Benzene is often referred to as PhH. Phenyl groups usually adhere to other atoms or groups. Three phenyl groups are connected to the same carbon center in triphenylmethane Ph 3 CH e.g. most, if not all, phenyl compounds do not have the word ‘phenyl’ attached to them. For example, (C 6 H 5 Cl) found in chloro is commonly referred to as chlorobenzene, but can also be called phenyl chloride. Individual phenyl groups are found in certain (and rare) conditions: phenyl anion (C 6 H 5 ), phenyl cation (C 6 H 5 + ), and phenyl radical (C 6 H 5 ). Benzene (C 6 H...

Amino acids are the building blocks of protein. L-phenylalanine is an essential amino acid. It is the only form of phenylalanine found in proteins. D-phenylalanine is not an essential amino acid, and its role in the body is not currently understood. DL-phenylalanine is made in a lab. People use phenylalanine for a disorder that causes white patches to develop on the • Attention deficit-hyperactivity disorder (ADHD). Taking phenylalanine by • Chronic pain. Taking D-phenylalanine by mouth does not seem to reduce pain. There is interest in using phenylalanine for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful. When taken by mouth: L-phenylalanine is commonly consumed in foods. L-phenylalanine, D-phenylalanine, and DL-phenylalanine are possibly safe when used as medicine, short-term. Side effects might include anxiety, When applied to the skin: Phenylalanine cream is possibly safe when used short-term. Pregnancy: L-phenylalanine is commonly consumed in foods. But having too much phenylalanine during pregnancy can increase the chance of birth defects. For patients who process phenylalanine normally and have normal levels, it is fine to consume phenylalanine in typical food amounts, but Phenylketonuria (PKU) and other conditions that cause high levels of phenylalanine: Some people have inherited disorders, such as PKU, that cause their bodies to build up too much phenylalanine. This can cause developmental delay, Schizo...

\( \newcommand\) • The terms phenyl and phenol, along with benzene and benzyl, can confuse beginning organic chemistry students. Figure 1 shows what the four terms mean. Figure 1: The top two structures in Figure 1 are molecules. The -ene suffix of benzene might indicate that it is similar to an alkene. The -ol suffix of phenol indicates that it has an -OH group. The lower two structures in Figure 1 show groups. The line extending off without anything connected is the line that shows this is a group, which should be attached to something. For example, one might have phenyl chloride (C 6H 5Cl, also called chlorobenzene) or one might have benzyl chloride (C 6H 5CH 2Cl). (The structures of these two compounds are shown below in Figure 2.) The phenyl group is based simply on benzene, with one H removed. The benzyl group is based on methylbenzene (toluene), with one H removed from the methyl group. Figure 2 shows the molecules benzyl chloride and phenyl chloride; these are based on the groups discussed above. If you have the misfortune to come across the word benzol, be forewarned that this is an old German word for benzene. Similarly, toluol is a German word for toluene. Benzin is a German word for gasoline; it is related to the uncommon term benzine, used for some types of gasoline.

What is phenylketonuria? Phenylketonuria (PKU) is a rare genetic condition that causes an amino acid called phenylalanine to build up in the body. Amino acids are the building blocks of protein. Phenylalanine is found in all proteins and some artificial sweeteners. Phenylalanine hydroxylase is an enzyme your body uses to convert phenylalanine into tyrosine, which your body needs to create neurotransmitters such as epinephrine, norepinephrine, and dopamine. PKU is caused by a defect in the gene that helps create phenylalanine hydroxylase. When this enzyme is missing, your body can’t break down phenylalanine. This causes a buildup of phenylalanine in your body. Babies in the United States are screened for PKU shortly after birth. The condition is uncommon in this country, only affecting about PKU symptoms can range from mild to severe. The most severe form of this disorder is known as classic PKU. An infant with classic PKU may appear normal for the first few months of their life. If the baby isn’t treated for PKU during this time, they’ll start to develop the following symptoms: • • tremors, or trembling and shaking • stunted growth • hyperactivity • skin conditions such as • a musty odor of their breath, skin, or urine If PKU isn’t diagnosed at birth and treatment isn’t started quickly, the disorder can cause: • irreversible brain damage and intellectual disabilities within the first few months of life • behavioral problems and seizures in older children A less severe form...

Phenyl group is closely related to Nomenclature [ ] Usually, a "phenyl group" is synonymous with C 6H 5− and is Ph 3CH) has three phenyl groups attached to the same carbon center. Many or even most phenyl compounds are not described with the term "phenyl". For example, the chloro derivative C 6H 5Cl is normally called C 6H − 5), the phenyl cation ( C 6H + 5), and the phenyl C 6H • 5). Although Ph and phenyl uniquely denote C 6H 5−, substituted derivatives also are described using the phenyl terminology. For example, C 6H 4NO 2− is nitrophenyl, and C 6F 5− is pentafluorophenyl. Monosubstituted phenyl groups (that is, disubstituted benzenes) are associated with ortho (1,2-disubstitution), meta (1,3-disubstitution) and para (1,4-disubstitution). A disubstituted phenyl compound (trisubstituted benzene) may be, for example, 1,3,5-trisubstituted or 1,2,3-trisubstituted. Higher degrees of substitution, of which the pentafluorophenyl group is an example, exist and are named acc...
