The Most Abundant Protein

The Most Abundant Protein Have you ever wondered what the most abundant protein is? The answer depends on whether you want to know the most common protein in the world, in your body or in a cell. Protein Basics A protein is a polypeptide, a molecular chain of amino acids. Polypeptides are, indeed, the building blocks of your body. And, the most abundant protein in your body is collagen. However, the worlds most abundant protein is RuBisCO, an enzyme that catalyzes the first step in carbon fixation. Most Abundant on Earth RuBisCO, whose full scientific name is ribulose-1,5-bisphosphate carboxylase/oxygenase, according to Study.com, is found in plants, algae, cyanobacteria, and certain other bacteria. Carbon fixation is the main chemical reaction responsible for inorganic carbon entering the biosphere. In plants, this is part of photosynthesis, in which carbon dioxide is made into glucose, notes Study.com. Since every plant uses RuBisCO, it is the most plentiful protein on earth with nearly 90 million pounds produced every second, says Study.com, adding that it has four forms: Form I, the most common type is found in plants, algae, and some bacteria.Form II is found in different types of bacteria.Form III is found in some archaea.Form IV is found in some bacteria and archaea. Slow Acting Surprisingly, each individual RuBisCO is not all that efficient, notes PBD-101. The website, whose full name is Protein Data Bank, is coordinated by Rutgers University, the University of California, San Diego, and San Diego State University as a study guide for college students. As enzymes go, it is painfully slow, says PBD-101.  Typical enzymes can process a thousand molecules per second, but RuBisCO fixes only about three carbon dioxide molecules per second. Plant cells compensate for this slow rate by building lots of the enzyme. Chloroplasts are filled with RuBisCO, which comprises half of the protein. This makes RuBisCO the most plentiful single enzyme on the Earth. In the Human Body Around 25 percent to 35 percent of protein in your body is collagen. It is the most common protein in other mammals, too. Collagen forms connective tissue. It is found primarily in fibrous tissue, such as tendons, ligaments, and skin. Collagen is a component of muscle, cartilage, bone, blood vessels, the cornea of your eye, intervertebral discs, and your intestinal tract. Its a little harder to name a single protein as the most common in cells because the composition of cells depends on their function: Actin is a very common protein that is found in all eukaryotic cells.Tubulin is another important and abundant protein used in cellular division among other purposes.Histones, associated with DNA, are present in all cells.Ribosomal proteins are abundant since they are needed to produce other proteins.Red blood cells contain high concentrations of the protein hemoglobin, while muscle cells contain a high level of the protein myosin.

The Marriage (Same Sex Couples) Essay Example | Topics and Well Written Essays - 5000 words

The Marriage (Same Sex Couples) - Essay Example Same-sex marriage (also known as gay marriage) is marriage between two persons of the same sex sex/gender. Legal recognition of same-sex marriage or the likelihood to perform a same-sex marriage is some of the time alluded to as marriage equality or equivalent marriage, especially by supporters.

In May 2013, thirteen nations, and a few sub-national administrations, permit same-sex couples to wed. Uruguay and New Zealand have both sanctioned laws to legitimize same-sex marriage, which has come into energy in August 2013. Same-sex marriage laws have differed by jurisdiction, being differently treated through anauthoritative change to marriage laws, a court decision focused around protected certifications of fairness, or by immediate prominent vote. The acknowledgement of same-sex marriage is a political, cultural, rights issue, and even a religious issue in numerou s countries. Debates are continuously rising on the hot topic whether same-sex couples ought to be permitted for marriage, be obliged to hold an alternate status. Permitting that couples to wed lawfully is thought to be a standout among the most imperative of all human and civil rights.Gay marriage has been a discriminating point in numerous nations for ages. Around the year 2000, nations, e.g. America and the United Kingdom began affirming gay marriages, despite the fact that not everybody concurred with this choice.
