J chain The J Chain's molecular weight is approximately 15 kDa. It exhibits a standard immunoglobulin folding structure of two β-pleated sheets of four ribbons folded against one another. It has 8 cystine residues. Two of these residues link the α chains of IgA or the μ chains of IgM via disulfide bridges, effectively serving as the glue between two Fc regions of the antibody.

- The overall shape and structure of fibrous proteins are determined principally by their secondary structure. α-keratin is an intracellular globular protein comprising two long subunits, the α-helical portions of which form a coiled-coil structure as already described (Table 3 (view document))..6 Fibrous proteins. Most of the proteins described so far have been globular proteins. There are, however, some distinctive features that characterise fibrous proteins and we present here a general overview of these.

Structural Biochemistry/Proteins/Amino Acids Amino acids are molecules which contain both a carboxylic acid and an amine group. In amino acid, the carboxyl group is more acidic than the carboxylic acid. 2-amino acids, also known as alpha-amino acids, are a specific type of amino acid that makes up proteins.he side-chains of the acidic amino acids Asp and Glu have pK values of 3.9 and 4.1, respectively, whereas those of the basic amino acids Arg and Lys, have pK values of 12.5 and 10.8, respectively. Only the side-chain of His,with a pK value of 6.0, is ionized within the physiological pH range (6-8).

Investigating the microstructure of keratin extracted from wool: Peptide sequence (MALDI-TOF/TOF) and protein conformation (FTIR) â Investigations of keratins extracted from wool by reduction hydrolysis and by alkaline hydrolysis showed that their chemical compositions and secondary structures were similar to original wool. The keratin isolates were similar in amino acid, Amides I and II, and secondary structure to each other and to original wool.

A Review of Amino Acids An alpha-amino acid consists of an amino group, a carboxyl group, a hydrogen atom, and a distinctive R group bonded to a carbon atom, which is called the alpha-carbon because it is adjacent to the carboxyl (acidic) group. An R group is referred to as a side chain .(Stryer,1988).

- When the concentration of a given protein is known, the concentration and molecular weight can be used to determine the molar extinction coefficient. The extinction coefficient is determined using the Beer-Lambert law: A = ε ∙ L ∙ c. A is the absorbance at 280 nm, L is the light path (cm), c is protein concentration (g/L) and ε is the extinction coefficient (L g-1 cm-1). When the light path L = 1cm, ε = A/c.
