What category of macromolecules are sugar?


Is sugar a carbohydrate lipid or protein?

Simple carbohydrates: Various forms of sugar, such as glucose and sucrose (table sugar), are simple carbohydrates. They are small molecules, so they can be broken down and absorbed by the body quickly and are the quickest source of energy.

Which biological molecules are nucleic acids?

The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals.

What’s an example of nucleic acids?

Two examples of nucleic acids include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA). These molecules are composed of long strands of nucleotides held together by covalent bonds. Nucleic acids can be found within the nucleus and cytoplasm of our cells.

Why do we need to eat nucleic acids?

While you need nucleic acids in your body, you don’t need them in your diet. Humans have a very limited ability to take up the building blocks of nucleic acids, called nucleotides, from the digestive tract. Instead, we tend to make our own nucleotides, using amino acids as precursors.

Where are nucleic acid found in the body?


Does RNA store genetic information?

Like DNA, RNA can store and replicate genetic information; like protein enzymes, RNA enzymes (ribozymes) can catalyze (start or accelerate) chemical reactions that are critical for life. Although RNA is fragile, some ancient RNAs may have evolved the ability to methylate other RNAs to protect them.

Why is RNA important and what is its function?

RNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA.

What’s the difference between RNA and DNA virus?

DNA viruses contain usually double‐stranded DNA (dsDNA) and rarely single‐stranded DNA (ssDNA). These viruses replicate using DNA‐dependent DNA polymerase. Compared to DNA virus genomes, which can encode up to hundreds of viral proteins, RNA viruses have smaller genomes that usually encode only a few proteins.

What is the main function of DNA and RNA?

Key Points DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions. The sequence of nitrogen bases (A, T, C, G) in DNA is what forms an organism’s traits.
