Essential Fatty Acids (EFAs) are fats that are required by the human body‚ but cannot be made by the body; therefore they must be obtained from external forces such as food. EFAs are the building blocks of all fats and oils and are required for both metabolic processes and for fuel. EFAs form the main component in the fats carried in our blood stream (triglycerides)‚ fats stored in our bodies and of cell membranes (phospholipids). (Erasmus‚ 1993)‚ (Wikipedia‚ Essential Fatty Acids‚ 2012) Two fundamental

The trans community forms together in online spaces‚ such as forums or blogs‚ to support each other and discuss trans-related topics. In these “safe” online settings‚ protected by

ETHERS Classification of Ethers: Symmetrical ethers – two groups attached to O are identical Ex. CH3CH2OCH2CH3 – diethyl ether Unsymmetrical ethers – two groups attached to O are not identical Ex. CH3CH2OCH3 – ethyl methyl ether Physical Properties of Ethers: Ethers have much lower boiling points compared to alcohols of comparable MWs. BPs of ethers increases with increasing MW. BPs of isomeric ethers increase with increasing alkyl chain length. BPs of ethers are about the

Acid in the human stomach When people refer to acid they usually see it as a corrosive liquid that can dissolve metals or change the color of a substance. So they think of acid as a dangerous matter for the body and believe it can easily dissolve your skin. What I have previously listed are indeed properties of certain acids‚ such as Hydrofluoric Acid which can cause irreversible tissue damage if it comes in contact with skin‚ but not all acids are this strong. As a matter of fact what a lot of

(Fe3+ ) form. Ferric form is not usually absorbed in the body. In the stomach‚ there is low pH of 2 due to presence of gastric acids such as Hydrochloric and Ascorbic acids. These acids provide an acidic environment for reduction of ferric iron to ferrous (Fe2+). Ferrous iron can be absorbed in the body system. As in following equation of iron (iii) reaction with Ascorbic acid ‚ the product is iron (ii) chloride which is soluble 2 Fe3+ (s) + C6 H8 O6 (aq) → 2 Fe2+ (aq) + C6 H6 O6 (aq) + 2 H (aq)+
