  According to statistics from the World Health Organization (WHO), there are about 56 million deaths worldwide each year, of which more than 17 million people die from cardiovascular diseases, accounting for more than 31% of all death factors. In China, the prevalence of cardiovascular diseases is on the rise. It is estimated that there are 290 million people suffering from cardiovascular diseases, including 13 million strokes, 11 million coronary heart diseases, 5 million pulmonary heart diseases, 4.5 million heart failures, and rheumatism. There are 2.5 million congenital heart diseases, 2 million congenital heart diseases, and 270 million hypertension. Cardiovascular disease has a high mortality rate, a high disability rate, extremely high medical costs after illness, and severely impaired quality of life. Therefore, the treatment of cardiovascular disease focuses on early detection and early treatment. Troponin is a marker that reflects myocardial damage. It is a very specific...

  Citral  (CAS No. 5392-40-5) has a molecular formula of C10H16O and a molecular weight of 152.23. It is one of the most important representatives of open-chain monoterpenes. Exist in maple grass oil and Litsea cubeba oil. Natural citral is a mixture of two geometric isomers. The properties of citral Citral a (also known as geranial or trans-citral) is a colorless oily liquid with lemon aroma; the boiling point is 229°C, density is 0.8888 g/cm (20°C); it is easy to oxidize and turn yellow in the air. Citral is oxidized with ammoniacal silver oxide to obtain genomic acid. Citral b (also known as neral, cis-citral) is a colorless or light yellow liquid; it has a boiling point of 120°C and a density of 0.8869 g/cm (20°C). Both isomers are soluble in ethanol and ether. Under normal circumstances, citral is a mixture of the above two. It is a light yellow oily volatile liquid with a lemon scent. It is hardly soluble in water and soluble in organic solvents such as ethanol, ether, p...

  Food protein must be broken down into amino acids before it can be used by the body for tissue growth, maintenance, and repair.   Trypsin   is an enzyme found in pancreatic juice and is necessary for effective protein digestion. Impairment of trypsin production not only hinders the digestion process but also damages the pancreas. The production of trypsin outside of pancreatic tissue may be involved in the cancer process. Protein digestion Trypsin is a protein digestive enzyme found in pancreatic juice and is secreted into the small intestine during meals. Trypsin secreted by the pancreas is an inactive zymogen called trypsinogen. Once in the small intestine, an enzyme called intestinal peptidase is secreted from the intestinal cells, cutting off a small piece of trypsinogen to produce active trypsin. The activated trypsin in turn helps break down food proteins. It also activates other trypsinogen molecules, as well as other protein-digesting enzymes secreted together w...
