which protein is insoluble in water,which is present in muscle ?
Myosin is an insoluble protein found in muscle tissues. It plays a crucial role in muscle contraction and is not soluble in water. The other options are either soluble in water or not predominantly found in muscles.
in a-helix shaped protein , polypeptide chain is coild in helix shape approximate amino acids are included per turn of helix
An alpha-helix is a common structural motif in proteins. In an alpha-helix, the polypeptide chain is coiled in a helix shape, and approximately 3.6 amino acids are included per turn of the helix. This precise arrangement allows for the formation of hydrogen bonds that stabilize the helical structure.
which isn’t true reason of denaturation of protein ?
Denaturation of proteins can occur due to various factors such as detergents, changes in pH, and increases in temperature. Therefore, all the listed options (detergent, change in pH, increase in temperature) are true reasons for denaturation, making option 'none' the correct answer as it indicates that none of the given options is an incorrect reason.
Which is the reason of denaturation of protein ?
Denaturation of proteins can be caused by various agents including organic solvents, detergents, and concentrated alkali. These agents disrupt the secondary, tertiary, and quaternary structures of proteins, leading to loss of function. Therefore, the correct answer is 'all'.
in certain clynical chemistry tests removal of all protein materials , which chemical is added to sample ?
Trichloroacetic acid is commonly used in clinical chemistry tests for the precipitation and removal of proteins from samples. It is a strong acid that can denature proteins, making them insoluble and easily separable from the sample.
which is called as coenzyme ?
A coenzyme is an organic component that serves as a cofactor to assist enzyme function. Unlike inorganic cofactors, which are often metal ions, coenzymes are organic molecules, typically derived from vitamins.
Which of the following ions may be co-factor ?
Many enzymes require a metal ion as a co-factor for their catalytic activity. Common examples of such metal ions include $Zn^{2+}$ and $Cu^{2+}$. These ions help in stabilizing the structure of the enzyme and/or participate in the enzyme's catalytic mechanism.
which of the following is true ?
An enzyme is composed of an apoenzyme (the protein part) and a coenzyme (the non-protein part). The apoenzyme by itself is inactive, and it requires the coenzyme to become active. Thus, the correct statement is: Coenzyme (Inactive) + Apoenzyme (Inactive) ---> Enzyme (Active).
sucrose is hydrolyzed by enzyme
Sucrose is hydrolyzed by the enzyme invertase. Invertase catalyzes the hydrolysis of sucrose into glucose and fructose, which are simpler sugars. This process is essential in various biological and industrial processes.
fat soluble vitamin is
Vitamin A is a fat-soluble vitamin. Fat-soluble vitamins include vitamins A, D, E, and K. These vitamins are stored in the body's fatty tissue and liver, and they are absorbed along with fats in the diet. Unlike water-soluble vitamins (like Vitamin C and the B vitamins), fat-soluble vitamins can be stored in the body for long periods.
