PROTEINSBIOMOLECULESALZHEIMER'S diseaseThe salutary intersection of fundamental cell biology with the study of disease is well illustrated by the emerging elucidation of neurodegenerative disorders. Novel mechanisms in cell biology have been uncovered through disease-orientated research; for example, the ...
Discover globular protein, the globular protein definition, and learn if these proteins are soluble in water. See globular protein examples and...
Others, like titin (a protein found in muscle), are very large. Some proteins consist of a single amino acid sequence (polypeptide chain), while others are multimers of the same or different subunits. Organization of Protein Structure There are four levels of protein structure: primary, ...
Learn what is a protein molecule and what is involved at each level of protein molecular structure. Also see protein molecule examples and their...

The exoskeleton, secreted by the outer tissue layer, is composed of protein and a nitrogenous carbohydrate called chitin , which in crustaceans is fortified with calcium carbonate crystals. To grow, most arthropods either shed (molt) the exoskeleton periodically or grow as soft-bodied larvae before...
Protein synthesisis the synthesis ofproteins, including catalytic enzymes. This process is closely linked toamino acid synthesisas amino acids are the building blocks of proteins. Lipid synthesisis the synthesis oflipids, such asfatty acidsandphospholipids(for the synthesis of lipid membranes). ...
The catalytic activity of enzymes mostly depends on the presence of non-protein compounds called coenzymes. Cofactors are highly bound to apoenzymes; therefore, coenzymes cannot be isolated from apoenzymes without denaturation of the enzyme proteins. Biology definition: A coenzyme is a molecule ...
Examples of Protein Turnover Lesson Summary Frequently Asked Questions What causes protein turnover? Protein turnover can be triggered by various causes. For instance, the presence of excess proteins, damaged proteins, or incorrectly folded proteins leads to their degradation and thus allows new prot...
