Physiological buffer is the system that controls output of acids , bases or CO2 ( carbon dioxide). true or false?

Explain the role of salts in the coagulation of eggs mixtures Explain the role of acids in the coagulation of eggs mixture

Write the formulas and provide the associated name for each formula for the four acids that contain oxyanions of bromine.

Discuss effects of structure and of the medium on the strengths of acids and bases. Use examples to illustrate your explanation.

a few words, your own, about proteins, nucleic acids, lipids and carbohydrates. (small paragraph).

What is the function of B-ketoacyl-ACP synthase (KS) in biosynthesis of fatty acids? What is the mechanism?

Instrumental Analysis:

Amber is an excellent source of preserved ancient organisms. Many bacteria remain dormant inside insects trapped in the amber and may be extracted, cloned and studied. Since the amber may be dated using geological methods, such investigations are a valuable source of ancient genetic information for biologists. Suggest a method that will permit the determination of metabolic products such as nucleic acids, short peptides and fatty acids obtained from cloned ancient bacteria. State any special instrument conditions or configuration.

2) Trans fat

Select one:

a. Contribute more to cardiovascular disease than cholesterol does

b. Lower the LDL in our bodies

c. Are a form of cholesterol

d. Dissolve in water

e. Are saturated fatty acids

1. Given the following fatty acids: Caproic Acid, Valeric Acid, Stearic Acid, Oleic Acid, Arachidonic Acid, Palmitic Acid, Cerebronic Acid, Timnodonic Acid and Cervonic Acid.

1a. Group them into saturated and unsaturated fatty acids. Identify the number of

carbons and number of double bonds, if present. Give their biochemical name.

1b. Arrange them based on their melting point, from lowest to highest.
