Biochemistry

By looking at structures and formulas of amino acids one would have to say that carbon was the primary element making up amino acids.

Two water molecules can react to from hydrogen bonds. If one water molecule acts as an acid and donates a proton to another water molecule then hydronium ions an hydroxyl ions can be formed as well.

Calcium is not a vitamin, it's a mineral, but it is very important for healthy bones.

Vitamin D helps people absorb and use calcium.

Vitamin K seems to help prevent fractures in elderly people.

Glycosidic bonds are typically cleaved in hydrolysis reactions by enzymes called hydrolases.

Structural isomers also called constitutional isomers are different compounds that have same molecular formula but different molecular structure. Structural isomers have same number of each type of atoms but the atoms are connected in a different order in them.

Structural isomerism is seen in organic compounds. It can be due to different arrangement of carbon chain, due to different position of functional group on the carbon chain, due to different functional groups that give their family of compounds same molecular formula.

Difference in arrangement of atoms is visible if structural formulas are written for compounds having same molecular formula.

Like structural isomers, stereoisomers also have same molecular formula. Stereoisomers are not structural isomers. Stereoisomers have their atoms connected in same sequence( same constitution), but they differ in the arrangement of atoms in space.

Cis and trans isomers of alkenes are examples of stereoisomers. Carbon chain arrangement, position of functional groups, and everything that could be different in structural isomerism is same here.

Francis Crick coined the term "central dogma" in 1958. It refers to the flow of genetic information from DNA to RNA to protein in cells.

In the gaseous state, acetone is considered a gas. The term "vapor" is typically used to describe the gaseous state of substances that are normally in a solid or liquid state at room temperature, while "gas" refers to substances that are typically gaseous at room temperature.

Bananas grow on large herbaceous plants that are native to tropical regions. The plants require plenty of sunlight, warmth, and water to thrive. The fruit start as flowers and develop into clusters of bananas that grow downward from the plant. Once the bananas reach maturity, they are harvested for consumption.

1.) Increases in NADH, Succinyl CoA, ATP, Citrate inhibit citrate synthase.

2.) Increases in ATP will inhibitisocitrate dehydrogenase.

3.) Increases in succinyl CoA and NADH will inhibit succinate thiokinase.

Chitin is found in the kingdoms Animalia (animals) and Fungi.

In the animal kingdom, it is found in arthropods (crustaceans, insects, etc.), mollusks, and fish (scales of certain species of fish, such as carp). It is also found in the cell walls of fungi.

The classic D's of Vitamin D are deficiency, dietary sources, and daily requirements. Deficiency can lead to health issues like weak bones and compromised immune function, dietary sources include fatty fish and fortified foods, and daily requirements vary based on age and health status.

Ethylene gas is commonly used to ripen bananas. It is a natural plant hormone that triggers the ripening process by stimulating the production of enzymes responsible for fruit softening and color changes. Ethylene can be applied in controlled concentrations to accelerate the ripening of fruits like bananas.

Energy is always conserved in a chemical reaction. If heat of reaction is positive, the mixture gets heated and may require external cooling to continue the reaction in the forward direction. If the reaction is endothermic, i.e. heat of reaction is negative, the mixture gets cooled and may need external supply of heat to maintain the reaction in forward direction. When the reaction is at an equilibrium, the heat of reaction is either zero or the mixture has attained an equilibrium with some definite ratios of the reaction products. The total energy of the system is conserved.

No, chitin is not used for energy storage. It is a structural polysaccharide found in the exoskeletons of arthropods and the cell walls of fungi. It provides support and protection rather than serving as an energy storage molecule.

As you know that hydrogen bonding aids the formation of the secondary structures. Once these structures are formed (ie alpha helix, beta-sheet, beta-turn), the R groups now can interact with other R groups. In the tertiary structure, the weak interactions (ie hydrogen bonding, ionic bonding, van der waals interactions) aid in the 3D structure of the protein. Disulfide bonds form in the tertiary structure which add extra stability to the overall 3D shape of the protein.

good luck.

The endocrine system makes and releases hormones in the body. Hormones are chemical messengers that travel through the bloodstream to target cells to regulate various physiological processes such as metabolism, growth, and reproduction. The endocrine system includes glands such as the pituitary, thyroid, adrenal, and pancreas.

Water is one of them

You automatically assume 100 grams of this substance, just so that the percentages become weights in grams, then you divide by the molecular mass to get the number of moles of each element. Then you find the smallest value for moles of one of the elements and divide through, the numbers left over should be positive integers, but if they aren't then multiply all the numbers by an integer to get whole numbers for each element. That number is then used to give the empirical formula, which is the simplest formula. Assume 100g N H O

22.2g 1.59g 76.21g

While it is possible to predict likely secondary structures of a protein from its primary structure, only knowing the secondary structure, the general 3-D shape of local areas of the protein, cannot yield the primary structure.

Enzymes are needed because they act as biological catalysts, speeding up chemical reactions in the body. They are essential for various cellular functions such as digestion, metabolism, and energy production. Without enzymes, many biochemical reactions would occur too slowly to sustain life.

The Anthrone test is a chemical test used to detect the presence of carbohydrates, specifically monosaccharides and disaccharides, in a sample. It involves adding Anthrone reagent to a sample, which produces a blue color in the presence of carbohydrates. The intensity of the blue color can be used to estimate the concentration of carbohydrates in the sample.

The storage polysaccharide found in plants is starch. Starch is a complex carbohydrate made up of glucose units and serves as a primary energy storage molecule in plants. It is typically stored in plant cells in the form of amylose and amylopectin.

Different vitamins provide different things for the human body. Mainly, vitamins are used so that our body stays healthy. For example, Vitamin C stops scurvy and also fights against flus. Vitamin A helps assist helathy night vision and Vitamin D is absorbed in order to have better calcium absorption. i hope this answers your question.

Theophylline relaxes smooth muscles which has been beneficial to those with asthma and is the reason why after drinking caffeine the person often feels the need to use the bathroom as it is affecting the smooth muscle of the colon. -- http://www.energyfiend.com/2010/01/caffeine-metablolism

steroids...

The steroids are a group of lipids with no fatty acids. This group includes cholesterol, Bile Salts, and steroid hormones (which includes sex hormones).
