Muscle Insertion. The insertion of the muscle is the end of the muscle attaching to the freely moving bone of its joint. To understand muscles and joint movements, there are four things to keep in mind: Movement happens at joints, with one bone of the joint moving freely while the other remains relatively stationary.
Aldehyde vs Ketone. Aldehydes and ketones are known as organic molecules with a carbonyl group. In a carbonyl group, carbon atom has a double bond to oxygen. The carbonyl carbon atom is sp2 hybridized. So, aldehydes and ketones have a trigonal planar arrangement around the carbonyl carbon atom. The carbonyl group is a polar group, thus, aldehydes and ketones have higher boiling points compared to the hydrocarbons having the same weight.
Aldehydes and ketones have higher melting and boiling points than hydrocarbons of equivalent molecular weight. This is due to the attraction between molecule due to the polarity of the carbonyl group.ldol Condensation. The aldol condensation is a reaction in which aldehydes and ketones react to form larger molecules. A new carbon-carbon bond is formed. In this generalized reaction the a-carbon of one aldehyde forms a bond with the carbonyl carbon of the other aldehyde.
