Amino acids are fundamental molecules of life. Amino acids contain an amine group, a carboxylic acid group, and a side chain (R) that varies between different amino acids. Amino acids contain the key elements of carbon, hydrogen, oxygen, and nitrogen. In an alpha amino acid, the amino ...
The amino acid lysine has the formula H2N(CH2)4CH(NH2)COOH. Which functional group is the cause of its basic properties? a) OH b) CO c) NH2 d) CH2 Which part of an amino acid's structure makes it unique from other amino acids?
Properties of Amino Acids (pKa, pKb, pKx, pl) The properties of α-amino acids are complex, yet simplistic in that every molecule of an amino acid involves two functional groups: carboxyl (-COOH) and amino (-NH2). Each molecule can contain a side chain or R group, e.g. Alanine is ...
The two functional groups that are bound to the central carbon atom of every free amino acid monomer are a carboxylic acid group and an amine group. ... Learn more about this topic: Amino Acids | Definition, Types & Structure from
Saturated fatty acids All single bonds along the tail (not including the end functional group) No C=C double bonds –long, straight chain –most animal fats –solid at room temp. contributes to cardiovascular disease = plaque deposits
11.3.2.1 Amino acids The organic compounds that contain a functional amino group (NH2) and a carboxyl group (COOH) along with a side chain (R) are known as amino acids. The essential elements of an amino acid are hydrogen, carbon, oxygen, and nitrogen. There are around 5000 synthetically...

The occurrence of extraterrestrial organic compounds is a key for understanding prebiotic organic synthesis in the universe. In particular, amino acids have been studied in carbonaceous meteorites for almost 50 years. Here we report ten new amino acids i
Amino Acids, Peptides and Proteins 5.20.7 Relevance of Amino Acids 5.20.7.1 What Is an Amino Acid? Amino acids are bifunctional compounds and the basic structural units/building blocks of proteins. In chemistry, an α-amino acid consists of an amino group, a carboxyl group, an R-group, an...
thermal enthalpy and free energy of all the amino-acids found be negative. Further, the free energy of arginine, cysteine,methionineandtryptophanfound to be most negative. Further,dipole momentwas calculated to study how the alkyl or the functional group influence the polarization. It is reported ...
