. whyOnly D sugars are biologically important?
Only D-sugars occur naturally in biological systems because of the specificity of enzymes and biochemical pathways that evolved to recognize and metabolize these forms. The D-configuration refers to the orientation of the hydroxyl group on the penultimate carbon in the sugar molecule, which aligns with the stereochemistry of most naturally occurring sugars. This selectivity ensures that D-sugars are effectively utilized in processes like glycolysis and other metabolic pathways, while L-sugars are generally not used or recognized by these biological systems.

The oxidation product of d-ribose is ribonate, which is a keto sugar formed by the oxidation of the aldehyde group in d-ribose. This process involves the conversion of the primary alcohol group in d-ribose to a carboxylic acid group. Ribonate is not commonly found in biological systems, as d-ribose is primarily used as an important component in nucleic acids.
L-sugars are not found in nature because most organisms synthesize D-sugars, which have a different configuration at the chiral carbon. This is due to the enzymatic processes that occur in living organisms which specifically produce D-sugars. Consequently, L-sugars are not common in nature and are not widely utilized by living organisms.
Sugar is a carbohydrate. Fat is a lipid. A lipid is a biological compound that is not soluble in water. Fat is in every fruit, and vegetable. Also in an apple. If you don't eat fat, that means you starve yourself. Fat contains Vitamin A, C, and E. Other vitamins fat contain are Iron, Calcium, Vitamin D, and more. You need sugar because sugar actually fuels your body. But watch out. Do not contain too much sugar and fat in a day. You only need 32 grams of sugar a day and 40 grams of fat per day to.
The building block of steroid hormones and vitamin D is cholesterol. Cholesterol serves as the precursor molecule for the synthesis of these important biological compounds in the body.
Yes, Sunlight is an important source of vitamin D. But it is not the only one.

i think they r glucose, fructose, and galactose
i would tell you, but Na :D
D-glucose is the most abundant D-aldohexose in the biological world. It is a primary source of energy for living organisms and plays a key role in cellular respiration and other metabolic processes.
