Arsenic forms colorless, odorless, crystalline oxides As 2 O 3 ("white arsenic") and As 2 O 5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic(V) acid is a weak acid and the salts are called arsenates , [ 5 ] the most common arsenic contamination of groundwater , and a problem that affects many people.
Fructose (/ ˈ f r ʌ k t oʊ s,-oʊ z /), or fruit sugar, is a ketonic simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose.It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed by the gut directly into the blood of the portal vein during digestion.
Arsenic biochemistry is the set of biochemical processes that can use arsenic or its compounds, such as arsenate. Arsenic is a moderately abundant element in Earth's crust, and although many arsenic compounds are often considered highly toxic to most life, a wide variety of organoarsenic compounds are produced biologically and various organic ...
Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the increasing recognition of the toxicity of arsenic and its compounds. [15] Arsenic has been known since ancient times to be poisonous to humans. [16]
Barley sugar – similar to hard caramel; Beet sugar [1] – made from sugar beets, contains a high concentration of sucrose; Birch syrup – around 42-54% fructose, 45% glucose, plus a small amount of sucrose; Brown sugar [1] – Consists of a minimum 88% sucrose and invert sugar. Commercial brown sugar contains from 4.5% molasses (light brown ...
Other reactions of main group compounds with yellow arsenic have been shown to involve units of arsenic with more than four atoms. In reaction with the silylene compound [PhC(NtBu) 2 SiN(SiMe 3) 2], an aggregation of As 4 was observed to form a cage compound of ten arsenic atoms, including a seven-membered arsenic ring at its center.

Fructose can be bad for your health when consumed as part of high-fructose corn syrup in processed foods. Past studies have linked high-fructose corn syrup intake to many diseases, including cancer.
Diamond and graphite are two allotropes of carbon: pure forms of the same element that differ in crystalline structure.. Allotropy or allotropism (from Ancient Greek ἄλλος (allos) ' other ' and τρόπος (tropos) ' manner, form ') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.
