Detecting Protein-Protein Interactions. Interactions. June 18, 2015. Why PPI?. Protein-protein interactions determine outcome of most cellular processes. Proteins which are close homologues often interact in the same way. Protein-protein interactions place evolutionary constraints on protein sequence and structural divergence. 2. Proteins (. Polypeptides. ). Chains of Amino acids (. 20. different kinds). bonded together by . peptide bonds. . (. polypeptides. ). Made of . Nitrogen, Carbon, Oxygen, and Hydrogen. Functions:. (endoplasmic reticulum). Dr. Mamoun Ahram. Faculty of Medicine. Second year, Second semester, 2014-2014. Principles of Genetics and Molecular Biology. An overview. Endoplasmic reticulum (ER). It is a network of membrane-enclosed tubules and sacs (. Interactions. June 6, 2017. Why PPI?. Protein-protein interactions determine outcome of most cellular processes. Proteins which are close homologues often interact in the same way. Protein-protein interactions place evolutionary constraints on protein sequence and structural divergence. June 12, 2018. Why PPI?. Protein-protein interactions determine outcome of most cellular processes. Proteins which are close homologues often interact in the same way. Protein-protein interactions place evolutionary constraints on protein sequence and structural divergence. Protein Synthesis (Gene Expression) Notes. Proteins . (Review). Proteins make up all . living. materials. Proteins are composed of . amino acids. – there are . 20. . different amino acids. Different . Most abundant molecule in cells making up 50% or more of their dry weight. Every protein has a unique structure, or shape. Allows it to perform a specific function. Enzymes are proteins that function as catalysts for many reactions in foods. Proteins are polymers of amino acids produced by living cells in all forms of life.. A large number of proteins exist with diverse functions, sizes, shapes and structures but each is composed of essential and non-essential amino acids in varying numbers and sequences.. Objectives:. Know the basic terminology related to fats and proteins. . Know the classifications of fats and proteins.. Basic terminology related to fats and proteins. Fat. denotes an ester composed of glycerol (tri-hydric alcohol) and three fatty acids of (triacylglycerol or triglycerides).. Protein . is a very important nutrient. It makes up most of our body cells, tissues and fluids. .. Protein . Deficiency. -Leads to Kwashiorkor in children Happens mostly in impoverished countries where there is a lack of protein rich foods. .  . Amino . Acids are the building units of proteins. There are about 300 amino acids occur in nature. Only 20 of them enter in proteins synthesis..  . Structure of amino acids:. Four different . groups . Size. Colloidal solutions. Charge. UV absorption. Solubility. Physical properties. Molecular weight. :. Vary from. 6000 . to million Daltons (Da) . Protomeric. proteins. : 50. . 000 . to. 100. . This has proved to be a very challenging problem. It has aptly been described as the second half of the genetic code, and as the three-dimensional code, as opposed to the one-dimensional code involved in nucleotide/amino acid sequence. .
