Amino Structure

Amino acids play central roles both as building blocks of proteins and as intermediates in metabolism. The 20 amino acids that are found within proteins convey a vast array of chemical versatility. Tertiary Structure of a proteinThe precise amino acid content, and the sequence of those amino acids, of a specific protein, is determined by the sequence of the bases in the gene that encodes that protein.

Amino Acid Synthesis

Amino acids are the monomers which are polymerized to produce proteins. Amino acid synthesis is the set of biochemical processes (metabolic pathways) which build the amino acids from carbon sources like glucose. Not all amino acids may be synthesized by every organism, for example adult humans have to obtain 8 of the 20 amino acids from their diet.

Structure of Amino Acids

When you try to sort twenty of anything into categories there are bound to be some 'grey' cases where people disagree and the classifying of amino acids is no exception. Amino acids are generally divided into groups on the basis of their side chains (R groups). The most helpful start-point, in terms of the resulting properties, is to separate amino acids into those with polar side chains and those with nonpolar side chains and then to sub-divide the polar amino acids dependant upon any charge that the R group might carry.

Antibody Packages

Antibodies are produced by a kind of white blood cell called a B cell. There are several different types of antibody heavy chain, and several different kinds of antibodies, which are grouped into different isotypes based on which heavy chain they possess.
