Energy in sugar molecules.

• Aldehyde - healthy,
•  - versus -
• Ketone - un-healthy

The reason behind the ketogenic diet.

Energy for life

• stored mostly in carbon, some nitrogen,
• released when reacted with oxygen
• burning fosil fuels forces oxygen to react with carbon
• for body temperature the oxygen must be composed with the carbon

<aldehyde>

• reactive oxygen on an end carbon atom, can react easily

<ketone> a chain of carbon with the reactive oxygen NOT at the end, cannot react eaisly

• reactive oxygen on a mid carbon, annot react easily

 The side product of releasing energy:

• carbon-dioxide - CO₂
• nitrogen-dioxide - NO₂
• same, body energy / fosil fuel energy
• breathed out when we loose weight

Yes, we cannot burn weight, we breath out pounds / kilos even as we sleep.

How do I loose weight?

• Breathing

How do I loose belly fat?

• Difficult

Aldehydes and ketones contain the carbonyl group.Double bonded oxygen to carbon.

Aldehydes are considered the most important functional group, gives life (oxygen) to carbon (oil).

They are often called the formyl or methanoyl group. Aldehydes derive their name from the dehydration of alcohols. Aldehydes contain the carbonyl group bonded to at least one hydrogen atom. Ketones contain the carbonyl group bonded to two carbon atoms.

Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O.

The carbon atom of this group has two remaining bonds that may be occupied by hydrogen, alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde. If neither is hydrogen, the compound is a ketone.

Naming Aldehydes

The IUPAC system of nomenclature assigns a characteristic suffix -al to aldehydes. For example, H₂C=O is methanal, more commonly called formaldehyde. Since an aldehyde carbonyl group must always lie at the end of a carbon chain, it is always is given the #1 location position in numbering and it is not necessary to include it in the name. There are several simple carbonyl containing compounds which have common names which are retained by IUPAC.

Also, there is a common method for naming aldehydes and ketones. For aldehydes common parent chain names, similar to those used for carboxylic acids, are used and the suffix –aldehyde is added to the end. In common names of aldehydes, carbon atoms near the carbonyl group are often designated by Greek letters. The atom adjacent to the carbonyl function is alpha, the next removed is beta and so on.
