In triglycerides , the main group of bulk lipids, there is one molecule of glycerol and three fatty acids. Fatty acids are considered the monomer in that case, and may be saturated no double bonds in the carbon chain or unsaturated one or more double bonds in the carbon chain.
In general, the bulk of their structure is nonpolar or hydrophobic "water-fearing" , meaning that it does not interact well with polar solvents like water.
Another part of their structure is polar or hydrophilic "water-loving" and will tend to associate with polar solvents like water. This makes them amphiphilic molecules having both hydrophobic and hydrophilic portions. In the case of cholesterol , the polar group is a mere —OH hydroxyl or alcohol. In the case of phospholipids, the polar groups are considerably larger and more polar, as described below. Most oils and milk products that we use for cooking and eating like butter , cheese , ghee etc.
Vegetable oils are rich in various polyunsaturated fatty acids PUFA. Lipid-containing foods undergo digestion within the body and are broken into fatty acids and glycerol, which are the final degradation products of fats and lipids.
Lipids, especially phospholipids , are also used in various pharmaceutical products , either as co-solubilisers e. Proteins are very large molecules—macro-biopolymers—made from monomers called amino acids. The side chain "R" is different for each amino acid of which there are 20 standard ones. It is this "R" group that made each amino acid different, and the properties of the side-chains greatly influence the overall three-dimensional conformation of a protein.
Some amino acids have functions by themselves or in a modified form; for instance, glutamate functions as an important neurotransmitter. Amino acids can be joined via a peptide bond.
In this dehydration synthesis, a water molecule is removed and the peptide bond connects the nitrogen of one amino acid's amino group to the carbon of the other's carboxylic acid group.
The resulting molecule is called a dipeptide , and short stretches of amino acids usually, fewer than thirty are called peptides or polypeptides. Longer stretches merit the title proteins.
As an example, the important blood serum protein albumin contains amino acid residues. A schematic of hemoglobin. The red and blue ribbons represent the protein globin ; the green structures are the heme groups. For instance, movements of the proteins actin and myosin ultimately are responsible for the contraction of skeletal muscle. One property many proteins have is that they specifically bind to a certain molecule or class of molecules—they may be extremely selective in what they bind.
Antibodies are an example of proteins that attach to one specific type of molecule. Antibodies are composed of heavy and light chains. Two heavy chains would be linked to two light chains through disulfide linkages between their amino acids.
Antibodies are specific through variation based on differences in the N-terminal domain.
Probably the most important proteins, however, are the enzymes. Virtually every reaction in a living cell requires an enzyme to lower the activation energy of the reaction. These molecules recognize specific reactant molecules called substrates ; they then catalyze the reaction between them.
By lowering the activation energy , the enzyme speeds up that reaction by a rate of or more; a reaction that would normally take over 3, years to complete spontaneously might take less than a second with an enzyme.
The enzyme itself is not used up in the process, and is free to catalyze the same reaction with a new set of substrates.
Using various modifiers, the activity of the enzyme can be regulated, enabling control of the biochemistry of the cell as a whole. The primary structure of a protein consists of its linear sequence of amino acids; for instance, "alanine-glycine-tryptophan-serine-glutamate-asparagine-glycine-lysine-…".

Secondary structure is concerned with local morphology morphology being the study of structure. Tertiary structure is the entire three-dimensional shape of the protein.
This shape is determined by the sequence of amino acids. In fact, a single change can change the entire structure. The alpha chain of hemoglobin contains amino acid residues; substitution of the glutamate residue at position 6 with a valine residue changes the behavior of hemoglobin so much that it results in sickle-cell disease.
Finally, quaternary structure is concerned with the structure of a protein with multiple peptide subunits, like hemoglobin with its four subunits.
Not all proteins have more than one subunit.
They can then be joined to make new proteins. Intermediate products of glycolysis, the citric acid cycle, and the pentose phosphate pathway can be used to make all twenty amino acids, and most bacteria and plants possess all the necessary enzymes to synthesize them. Humans and other mammals, however, can synthesize only half of them. They cannot synthesize isoleucine , leucine , lysine , methionine , phenylalanine , threonine , tryptophan , and valine. These are the essential amino acids , since it is essential to ingest them.
The three-dimensional shape of a protein determines its function. The shape of proteins can change by small or large amounts; another term for shape is conformation.
Fluid bed granulation in the form of agglomeration and coating processes are important unit operations used for many purposes in the biochemical and pharmaceutical industries.
Membrane processes are key unit operations in almost all parts of the chemical, biochemical, and pharmaceutical downstream processing. This book starts off by discussing the basics of kinetics, using everyday examples.
Electrically driven membrane processes, and electrodialysis in particular, are important unit operations, especially within the field of desalination - making tab water from sea water. In many types of biochemical and pharmaceutical industries fluid bed granulation in the form of agglomeration and coating processes are essential unit operations in the production of solid products.
