Although there is little information on what is the optimum calorie:proteinratio for pigs, it may be possible to extrapolate ratios fromstandard grain-soybean meal diets to those with high levels ofadded fat (> 5 percent).

Different proteins are made by using different sequences and varying numbers of amino acids.

are the most diverse biomolecules on Earth, performing many functions required for life. Protein are biological catalysts, maintaining life by regulating where and when cellular reactions occur. Structural proteins provide internal and external support to protect and maintain cell shape. For example, keratins are an important class of structural proteins found in the hair, skin, nails, and feathers of animals. Motility proteins provide the basis for cellular and whole organism movement, including muscle motor proteins that can move entire animals! Membrane proteins transmit signals during cell-to-cell communication, transport molecules into and out of cells, and protect living organisms by identifying and flagging invaders.

Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the . Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks.

• To ensure that the overall concentration of primers is sufficiently high, primers with 128-fold degeneracy or less are recommended by Springer protocols. The complete degeneracy of the primer is obtained by multiplying together the degeneracy of each amino acid in the designed sequence.

codifies one amino acid of a protein.

Another way of describinga limiting amino acid is thinking of protein as a rain barreland the amino acids as the individual staves making up the barrel.


Living organisms synthesize almost all proteins using only twenty different amino acids. Polypeptides form a unique three-dimensional structure based on the type and position (sequence) of these amino acids. Within the sequence, amino acid R-groups form chemical interactions that create a specific three-dimensional structure. These R-groups are commonly called “side chains” because they are not involved in the peptide bonds. The R-groups stick out on the side of a polypeptide, freeing them to chemically interact with one another. Side chain interactions form each protein’s specific structure, a structure uniquely capable of performing that protein’s cellular function.

However, it is important to rememberthat this is not always true when using synthetic amino acidsand alternative or by-product feed ingredients, and that the dietarylevels of amino acids should always be checked.

Amino acid synthesis - Wikipedia

Unlike polysaccharides, polypeptide chains are assembled with a wide variety of amino acids in each polymer. The set of twenty amino acids commonly found in biological proteins is directly responsible for the diversity of protein structures in living cells. Each protein differs in several aspects that determine structure and, therefore, function. A protein may be composed of one or more polypeptide strands. A cell’s genes determine the length of each polypeptide strand, as well as the type and position of each amino acid in the sequence. Together, these factors determine protein structure, which determines the function a protein can perform.

When formulating diets with commonly available grains and proteinsources, the level of crude protein typically used to describethe diet usually will contain adequate amounts of amino acidsto meet the pig's requirement.
