Peptide hormones have a structure based on proteins and peptide bonds, in contrast to steroid hormones where the structure is based on carbon-based rings. There are several different peptide hormones including:Human growth hormone (hGH) – controls cell growth. Normal levels change at different ages...
Polyhormones: The examples of PTH and PTH-related peptideMallette, L. E.EXCERPTA MEDICA INTERNATIONAL CONGRESS SERIES
The primary structure of a protein is the specific number and order of amino acids that make up the protein chain, called a polypeptide, a simple protein molecule. The individual amino acids are linked together with a peptide bond between the carboxyl group of one amino acid and the amine gr...
This information directs ribosomes to link small amino acids together forming a specific protein. Proteins are important components of many biological structures, such as tissues and organs. They form hormones and enzymes that carry signals between different cells as well as control chemical reactions...
peptide linkage hydrolysis, breaking carbon bonds,andthe conversion of substances to their optical isomers. In these reactions, enzymes may or may not function alone, enzymes may need the assistance of acofactor. Aholoenzymeor an active enzyme is a complex that consists of two parts: the protein...
Water is absorbed down the osmotic gradient by principal cells, through the apical aquaporin-2 (AQP-2) and basolateral aquaporin-3 and aquaporin-4 (Fig. 63-3).Renal tubular reabsorption of filtered Na+-Cl– is regulated by multiple circulating and paracrine hormones, in addition to the ...

Some of the functions of the glycoproteins include protecting the epithelial cells, release glycoprotein hormones from the anterior pituitary gland like follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, and human chorionic gonadotropin. They aid in cell adhesion, as cellular mar...
peptide structure and eventually a complex folded protein molecule. Proteins are used for a variety of functions, like, enzymes that catalyse various biochemical processes are protein molecules. Hormones required for the metabolic andgrowthprocesses are also proteinaceous molecules. Antibodies that protect ...
