Inositol
Inositol, or more precisely ''myo''-inositol, is a carbocyclic sugar that is abundant in the brain and other mammalian tissues; it mediates cell signal transduction in response to a variety of hormones, neurotransmitters, and growth factors and participates in osmoregulation. It is a sugar alcohol with half the sweetness of sucrose (table sugar). It is made naturally in the human body from glucose. A human kidney makes about two grams per day. Other tissues synthesize it too, and the highest concentration is in the brain, where it plays an important role by making other neurotransmitters and some steroid hormones bind to their receptors. Inositol is promoted as a dietary supplement in the management of polycystic ovary syndrome ( PCOS). However, there is only evidence of very low quality for its efficacy in increasing fertility for IVF in women with PCOS. Overview ''myo''-Inositol plays an important role as the structural basis for a number of secondary messengers in eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1D-chiro-Inositol
1D-''chiro''-Inositol (formerly D-''chiro''-inositol, commonly abbreviated DCI) is a member of a family of related substances often referred to collectively as " inositol", although that term encompasses several isomers of questionable biological relevance, including 1L-''chiro''-inositol. ''myo''-Inositol is converted into DCI by an insulin dependent NAD/NADH epimerase enzyme. It is known to be an important secondary messenger Second messengers are intracellular signaling molecules released by the cell in response to exposure to extracellular signaling molecules—the first messengers. (Intercellular signals, a non-local form or cell signaling, encompassing both first m ... in insulin signal transduction. DCI accelerates the dephosphorylation of glycogen synthase and pyruvate dehydrogenase, rate limiting enzymes of non-oxidative and oxidative glucose disposal. DCI may act to bypass defective normal epimerization of ''myo''-inositol to DCI associated with insulin resistance a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isomer
In chemistry, isomers are molecules or polyatomic ions with identical molecular formulae – that is, same number of atoms of each element – but distinct arrangements of atoms in space. Isomerism is existence or possibility of isomers. Isomers do not necessarily share similar chemical or physical properties. Two main forms of isomerism are structural or constitutional isomerism, in which ''bonds'' between the atoms differ; and stereoisomerism or spatial isomerism, in which the bonds are the same but the ''relative positions'' of the atoms differ. Isomeric relationships form a hierarchy. Two chemicals might be the same constitutional isomer, but upon deeper analysis be stereoisomers of each other. Two molecules that are the same stereoisomer as each other might be in different conformational forms or be different isotopologues. The depth of analysis depends on the field of study or the chemical and physical properties of interest. The English word "isomer" () is a back ...

Allo-Inositol

Epi-Inositol
''Epi''-Inositol is one of the stereoisomers of inositol. Use in medicine Epi-inositol has been found to regulate Yeast Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The first yeast originated hundreds of millions of years ago, and at least 1,500 species are currently recognized. They are estimated to constit ...

Neo-Inositol
''neo''-Inositol is one of the stereoisomers of inositol Inositol, or more precisely ''myo''-inositol, is a carbocyclic sugar that is abundant in the brain and other mammalian tissues; it mediates cell signal transduction in response to a variety of hormones, neurotransmitters, and growth factors and .... It is one of the nine isomeric forms of cyclohexanehexol; a group of small and chemically very stable polar molecules that have versatile properties. This stereoisomer is naturally occurring, but only in small amounts. It is also known as (1s,2R,3R,4s,5S,6S)-cyclohexane-1,2,3,4,5,6-hexol or 1,2,3/4,5,6-cyclohexanehexol in the IUPAC naming system.

Scyllo-Inositol
''scyllo''-Inositol is one of the stereoisomers of inositol. It is also known as scyllitol, cocositol, quercinitol, and 1,3,5/2,4,6-hexahydroxycyclohexane. ''scyllo''-Inositol is a naturally occurring plant sugar alcohol found most abundantly in the coconut palm. Biological effects Researchers at the University of Toronto have found that ''scyllo''-inositol can block the development of amyloid-beta (Aβ) plaques in the brains of transgenic mice. ''scyllo''-Inositol also reversed memory deficits, reduced the formation of Aβ plaques, and alleviated other symptoms that are associated with the accumulation of Aβ proteins in these mice. Researchers at the Harvard Medical School-affiliated McLean Hospital identified that chronic users of anabolic steroids had statistically significantly lower levels of brain scyllo-inositol levels as compared to non-users.
