protein with 607 amino acids‚ and the average molecular weight of a single amino acid is 135 g/mole. Which of the following will be able to diffuse through the 200 MWCO membrane? Your answer : c. glucose only Stop & Think Questions: The reason sodium chloride didn ’t diffuse left to right is that You correctly answered: c. the membrane pore size was too small. Glucose is a six-carbon sugar. Albumin is a protein with 607 amino acids. The average molecular weight of a single amino acid is 135 g/mole

The basic structure of all the penicillins consists of a thiazolidine ring fused with a beta-lactam ring‚ creating a fundamental nucleus (also known as 6-amino penicillanic acid) crucial for their antibacterial activity. A wide variety of semisynthetic penicillins are produced by altering the composition of the side chains attached to this nucleus.The molecular formula of penicillin is C16H18N2O4S and weight of 334.39 g/mol‚ each base with a variable side chain‚ “R” that differentiates the penicillins

BIURET FOOD TEST FOR PROTEINS molecules consisting of one or more chains of amino acids.Proteins are complex molecules that react differently to many compounds but are also fragile and cannot withstand high temperatures or strong acids and bases without degrading. The Biuret Method‚ or biuret test‚ is used to detect the presence of peptide bonds. It has this name because it reacts positively to the biuret molecule’s peptide bonds. Correctly evaluating the number of peptide bonds is a step towards

Introduction What is Protein? There are more than 300 amino acids in the nature. However‚ only 20 amino acids are joined by each other with peptide bonds in different sequences and numbers. These sequences are formed by helping of genetic information which is encoded in genes. So‚ each protein molecule has its own amino acid sequence. Proteins are most abundant long chain macromolecules in all cells and they serve as structure and function matter in cells of all living organisms such as hormones

A. Proteins- A protein is a naturally produced macromolecules that are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and chains of amino acids. The amino acids are building blocks for all our cells. Proteins main function is to help in tissue repair and growth. There are three different types of proteins. Fibrous proteins help in forming muscle tissues‚ tendons‚ bones‚ and connective tissue and some examples of these are Actin‚ Coronin‚ Elastin‚ and Myosin. Globular proteins help in regulating

2014 I. Structure Myoglobin is almost similar in structures with hemoglobin except on the heme groups attached to it and to the presence of amino acids. Myoglobin only seems like a quarter of hemoglobin. Myoglobin has a molecular weight of 18‚ 000. It has a component of a single polypeptide chain folded into 8 α- helical structure‚ 153 amino acids and one heme group attached at the crevice of the molecule. It also contains iron protoporphyrin 9 as its prosthetic group. The single polypeptide
