Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage.. A carbohydrate (/ ˌ k ɑːr b oʊ ˈ h aɪ d r eɪ t /) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula C m ...
The α form of the tetrahydrate has density 1.33 g/cm 3. It melts congruously at 7.55 °C into a liquid with 35.7% NaOH and density 1.392 g/cm 3 , and therefore floats on it like ice on water. However, at about 4.9 °C it may instead melt incongruously into a mixture of solid NaOH·3.5H 2 O and a liquid solution.
A open-chain form of glucose makes up less than 0.02% of the glucose molecules in an aqueous solution at equilibrium. [57] The rest is one of two cyclic hemiacetal forms. In its open-chain form, the glucose molecule has an open (as opposed to cyclic) unbranched backbone of six carbon atoms, where C-1 is part of an aldehyde group H(C=O)−.
Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell.
Fatty acids are a major component of the lipids (up to 70% by weight) in some species such as microalgae [2] but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters.
In common with the other provinces of Pakistan, Balochistan has a parliamentary form of government. The ceremonial head of the province is the Governor, who is appointed by the President of Pakistan on the advice of the provincial Chief Minister.

[23] [32] [33] In the United States, methamphetamine's levorotary form is available in some over-the-counter (OTC) nasal decongestant products. [ 23 ] [ note 4 ] Although the pharmaceutical name "methamphetamine hydrochloride" may suggest a racemic mixture , Desoxyn contains enantiopure dextromethamphetamine, which is a more potent stimulant ...
