A connector acid with polyethylene glycol, which has the following structural formula: R-PEG-CO-X-amino acid or R-PEG-X-amino acid wherein the PEG is a polyethylene glycol chain, R is hydroxy or PEG hydrocarbon group, the hydrocarbon group may be selected from C1 ~ C12 alkoxy, cyclo...
Amino acid, any of a group of organic molecules that consist of a basic amino group, an acidic carboxyl group, and a unique organic side chain. The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Examples of amino acids include glyci

Aspartic acid, an amino acid obtainable as a product of the hydrolysis of proteins. First isolated in 1868 from legumin in plant seeds, aspartic acid is one of several so-called nonessential amino acids for mammals; i.e., they can synthesize it from oxal
155 Thus, the choice of an amino acid plays a very important role in biological and structural relevance. Alanine (abbreviated Ala or A) ((S)-2-aminopropanoic acid; α-aminopropionic acid) is a nonpolar, neutral, aliphatic amino acid with the formula HOOCCH(NH2)CH3. Ala plays a major ...
It is often used in mutational studies by replacing other amino acids with alanine to observe the structural and functional effects on the protein. Proline- a non-polar amino acid with the unique property of its carbon side chain linked to the amino group. As a result, an amino acid chain...
Each amino acid has a different isoelectric point, which is influenced by the number and type of charged groups present in the molecule. Amino acids with acidic side chains, such as aspartic acid and glutamic acid, have low isoelectric points, while those with basic side chains, such as argin...
Vertebrata lanosa; bromophenol; amino acid derivatives; dimethyl sulfonium; sulfate Graphical Abstract1. Introduction Vertebrata lanosa (L.) T.A. Christensen, formerly known as Polysiphonia lanosa (L.) Tandy, is a red alga belonging to the family of Rhodomelaceae. It is distributed commonly ...
2.3.3 Total and average amino acid property The total amino acid property for each residue type in a protein was computed using the following formula: (2.2)Ptotal(i)=P(i)*∑ni, where P(i) and ni are the property value and number of residues of ith-type residue. The summation is over...
