What group does nucleic acid belong to?
nucleic acid—–one phosphate group, one nitrogen containing base (pyrimidine or purine) and a sugar molecule, which in turn has alcohol and aldehyde/ketone group.
Do amino acids make up nucleic acids?
All nucleic acids are made up of the same building blocks (monomers). Just as there are twenty (20) amino acids needed by humans to survive, we also require five (5) nucleotides.
Are amino acids proteins or nucleic acids?
Types of biological macromolecules
| Biological macromolecule | Building blocks | Examples |
|---|---|---|
| Lipids | Fatty acids and glycerol | Fats, phospholipids, waxes, oils, grease, steroids |
| Proteins | Amino acids | Keratin (found in hair and nails), hormones, enzymes, antibodies |
| Nucleic acids | Nucleotides | DNA, RNA |
What is an amino acid structure?
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached.
Which element is found in nucleic acids but not in proteins?
Macromolecules
| A | B |
|---|---|
| element found in nucleic acids, but not proteins, carbs, or lipids | phosphorus |
| provides quick energy; also can be part of cell membrane, acting as an identification tag | carbohydrates |
| provides long-term energy; makes up the cell membrane; is a water barrier; acts as insulation | lipids |
Where are nucleic acids found in?
Although first discovered within the nucleus of eukaryotic cells, nucleic acids are now known to be found in all life forms including within bacteria, archaea, mitochondria, chloroplasts, and viruses (There is debate as to whether viruses are living or non-living).
What elements make up nucleic acids?
Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P). The body also needs trace amounts of other elements such as calcium, potassium, and sulfur for proper functioning of muscles, nerves, etc.
Where are amino acids in DNA?
Proteins are large, complex molecules made up of long chains of subunits called amino acids. Twenty different kinds of amino acids are usually found in proteins. Within the gene, each specific sequence of three DNA bases (codons) directs the cells protein-synthesizing machinery to add specific amino acids.
Is DNA made of amino acids?
DNA tells a cell how to make proteins through the genetic code. Both DNA and proteins are long molecules made from strings of shorter building blocks. While DNA is made of nucleotides, proteins are made of amino acids, a group of 20 different chemicals with names like alanine, arginine, and serine.
How do you categorize amino acids?
Amino acids can be classified based on the characteristics of their distinctive side chains as nonpolar, polar but uncharged, negatively charged, or positively charged. The amino acids found in proteins are L-amino acids.
What amino acids are Ionizable?
Functional groups of amino acids in enzymes present have the ability to readily ionize. other amino acids which have ionizable side chains. These include arginine, aspartic acid, cysteine, glutamic acid, histidine, lysine and tyrosine.
What elements are in nucleic acids but not amino acids?
Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).
What foods contain all 20 amino acids?
However, eating combinations of legumes, nuts and whole grains throughout the day provides you with all the amino acids you need. Soybeans are one of the few vegetarian foods that contain all the essential amino acids. Legumes, such as lentils, chickpeas, black beans and pinto beans, contain anywhere from 11 to 18 grams of protein per cup.
What are the four main amino acids?
Phenylalanine (PHE)
Are there 20 or 22 amino acids?
There are 22 Amino Acids. These above are the 20 more well-known amino acids; however, just how many amino acids exist actually are counted as being over 200 in numbers, but the 22 proteinogenic amino acids are the ones that are commonly known.
What are four examples of nucleic acids?
The many examples of nucleic acids including RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are composed of monomers called nucleotides. A nucleotide contains 3 components: a nitrogenous base, a phosphate group and a 5-carbon sugar. If the sugar is ribose, then its polymer is RNA.
