2014年1月17日 · The term carbohydrate can basically be translated into "carbon water". Therefore, the typical formula for a carbohydrate is CH_2O. --> Carbon with 2 Hydrogen and 1 Oxygen: C + H_2O The most common sugar is glucose from the photosynthesis reaction. Glucose has a formula of C_6H_12O_6. Sucrose which is table sugar is C_(12)H_(22)O_(11). Note that in each case the hydrogen is twice the oxygen ...

2016年8月31日 · Carbohydrates are polyhydroxy aldehydes or ketones or compounds which yield these on hydrolysis. The most common component of lipids in the body are the fatty acids. These are aliphatic carboxylic acids and have the general formula R-CO-OH where COOH [ carboxylic group ] represents the functional group.

2017年3月9日 · Let's take the very common carbohydrate, sugar..... Sugar has a formula of C_6H_12O_6, which, of course, has an empirical formula of 1:2:1 with respect to C, H, and O, or an empirical formula of CH_2O.

2015年2月27日 · CnH2nOn It's called carbohydrate because it contains as many (H2O) units as C units. The dehydration of carbohydrates leads to carbon. As an example the reaction of table sugar with concentrated sulphuric acid.

2016年2月7日 · The empirical formula is CH_2O, and the molecular formula is some multiple of this. In 100 g of the unknown, there are (40.0*g)/(12.011*g*mol^-1) C; (6.7*g)/(1.00794*g*mol^-1) H; and (53.5*g)/(16.00*g*mol^-1) O. We divide thru to get, C:H:O = 3.33:6.65:3.34. When we divide each elemental ratio by the LOWEST number, we get an empirical formula of CH_2O, i.e. near enough to WHOLE numbers. Now ...

2018年3月6日 · See Below There is generally 1 carbohydrate found in nucleic acids. That is the 5 carbon Aldose sugar called Ribose. RNA has a ribose sugar. If you remove the hydroxyl group on the second carbon of Ribose, you get something called 2`-dexoyribose. This is still Ribose, but is missing its OH group at carbon 2. This is the sugar used in DNA. RNA has a Ribose sugar, DNA has a 2`-deoxyribose sugar ...

2015年4月24日 · Differences between carbohydrates and Fats: Chemical composition and structure: Carbohydrates are polymers of monosaccharides, which are polyols (many OH groups) with an aldehyde or ketone functional group. Fats are esters of fatty acids and glycerol. Most carbohydrates are hydrophilic, smaller ones are soluble in water. Fats are hydrophobic. Carbohydrates are the first choice energy source in ...

2015年6月13日 · The structure of a small protein is Proteins have polar "C=O" and "N-H" groups, so they are able to form hydrogen bonds with other molecules and with each other. Carbohydrates Carbohydrates have many polar "OH" groups. A typical carbohydrate is starch, which is consists of many glucose units ("C"_6"H"_12"O"_6 ) joined together.

2017年6月7日 · Sometimes a chemical formula might even be written two different ways, and one way is clearer than another. Examples: #"CH"_3"COOH"#, or #"HC"_2"H"_3"O"_2#, are the same molecule, acetic acid: The first formula tells you the structure; it reads left to right correspondingly with the molecule.

2018年6月17日 · Easily by their structure of course... Carbohydrates and hydrocarbons are both organic groups of molecules, which both contain carbon and hydrogen in them. The main difference between these two classes of molecules is that hydrocarbons are only made of carbon and hydrogen, while carbohydrates contain carbon, hydrogen, and oxygen in them. As such, an example of a hydrocarbon would be propane (C ...
