Amino acidIn chemistry, an amino acid is a molecule containing both amine and carboxyl functional groups. These molecules are particularly important in biochemistry, where this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where R is an organic substituent. In the alpha ...
R 6 is H or COZ wherein Z is an amino acid, a peptide residue or a leaving group; and with the provisos that when n is 0 and R 3 is hydrogen, R 1 and R 2 are not hydrogen, halogen or nitro; that when n is 0 and R 3 is lower alkyl, R 1 and R 2 are not hydrogen;...
An amino acid is defined as an organic acid that contains at least one amino group. In the context of proteins, amino acids are the building blocks, with the amino group attached to the same carbon atom as the carboxyl group. AI generated definition based on:Cosmetic Science and Technology,...

Fig. 4.2.Two amino acids are linked by peptide bond. Peptide bond forms when amino group of one amino acid links with the carboxyl group of the other, with the loss of a molecule of water. Generally, there are two types of protein molecules:globular proteinsand fibrous proteins. Globular ...

Peptides When the amino group of one amino acid reacts with the carboxyl group of another amino acid, a peptide bond is formed and a molecule of water is released. This can bond joins amino acids together to form proteins The peptide bond is slightly shorter than otter single c-n bonds....
2.3.2 Amino acid composition The amino acid composition is the number of amino acids of each type normalized with the total number of residues. It is defined as (2.1)Comp(i)=∑ni*100/N, where i stands for the 20 amino acid residues; ni is the number of residues of each type, and ...
