Part Descriptions

LP15257-6   Calcium
Calcium is the most plentiful mineral in the human body. Ninety-nine percent is stored in the bones and teeth where it provides structure and functionality. The remaining 1% of the body's calcium is necessary for vascular contraction and vasodilation, muscle function, nerve transmission, intracellular signaling, and hormonal secretion. Serum calcium levels do not fluctuate in response to dietary intake. Bone tissue is the reservoir for calcium and helps to maintain concentrations in the blood, the muscle, and intercellular fluids. As humans age, the bone is constantly being laid down and reabsorbed. In growing children, bone formation exceeds that of bone resorption. In young and middle-aged adults, the bone formation and resorption is about equal. In older adults, especially in post-menopausal women, bone loss exceeds that of bone formation, which is why their risk for osteoporosis continues to increase as they age.[https://ods.od.nih.gov/factsheets/Calcium-HealthProfessional/] Source: Regenstrief LOINC

LP32142-9   Protein
Proteins are large organic compounds made of amino acids arranged in a linear chain and joined together between the carboxyl atom of one amino acid and the amine nitrogen of another. This bond is called a peptide bond. The sequence of amino acids in a protein is defined by a gene and encoded in the genetic code. Although this genetic code specifies 20 standard amino acids, the residues in a protein are often chemically altered in post-translational modification:either before the protein can function in the cell, or as part of control mechanisms. Proteins can also work together to achieve a particular function, and they often associate to form stable complexes. Like other biological macromolecules such as polysaccharides and nucleic acids, proteins are essential parts of all living organisms and participate in every process within cells. Many proteins are enzymes that catalyze biochemical reactions, and are vital to metabolism. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
