Are amides acylated amines?

In amidesone of the three bonds is a carbonyl carbon. Thus amides may be viewed as "acylated amines" or asderivatives of carboxylic acids in which the -OH of the acid has been replaced by -NR2 where R=H, alkyl, aryl, etc.): .. .. R".. .. R N .. O C O N .. C

What is the difference between 1° and 2° amines?

Hydrogen bonding between 1° and 2° amines is not as strong as those found in alcohols or carboxylic acids. 1° and 2° amines have lower boiling points than alcohols of similar molecular weight. 3° amines, since they do not hydrogen bond to each other, have boiling points similar to hydrocarbons of the same molecular weight.

How to classify amino acids based on chemistry?

Table 2.2 – Amino acid categories (based on R-group properties) Amino acids can be classified based on the chemistry of their R-groups. It is useful to classify amino acids in this way because it is these side chains that give each amino acid its characteristic properties.
