the digestive system and degrades proteins‚ making it an enzyme known as protease. [1] It is one of the three principal digestive proteinases‚ the other two being pepsin and chymotrypsin. [9] Trypsin primarily hydrolyses peptides into smaller building-blocks‚ mainly amino acids (these peptides are the result of the enzyme pepsin ’s breaking down the proteins in the stomach). This enables the uptake of protein in the food because peptides (though smaller than proteins) are too big to be absorbed through

reactions construct complex substances from simpler ones. · Anabolic processes use energy. · Protein synthesis is an example of an anabolic process. Protein Synthesis · Proteins are long chains of amino acids. · There are 20 common amino acids. · Instruction for the assembly of proteins (the number and sequence of the amino acids) is carried by DNA in the cell nucleus. · Ribosomes are protein construction sites. · Most ribosomes line the endoplasmic

splicing is a process cells use to produce different types of messenger RNA. These types of mRNA produce different variations of a protein. Serine-arginine-rich and heterogeneous nuclear ribonucleoproteins are two types of proteins also known as SR and hnRNPs‚ respectively. Due to the binding of enhancer sequences‚ SR proteins promote splice selection whereas HnRNP proteins utilize suppressor sequences

intended to represent an entire species history. METHODS: Isolation of Fish Protein using Lamelli Buffer Before starting anything we labeled 1.5 ml flip-top microtubes and screw top microtubes 1 through 8 for each fish sample that is being prepared for electrophoresis. Lamelli sample buffer is added to each flip-top microtube in 250 µl increments; this buffer is used to denature the fish protein. Our fish protein will come from eight different fish muscle samples that are cut in a cube that
